Earthquake is a serious threat for society development and its vulnerability is influenced by environmental variables. The damages of earthquakes are reduced by recognizing these variables and area zoning. The aim of this paper is the zoning of earthquake vulnerability of Sanadaj city based on effective variables. For this purpose, the final map of region’s natural vulnerability zoning and skeletal indices and other effective social indices have been used. The variables were changed to layers of GIS and then, overlapping were performed using AHP and TOPSIS models. Finally, the vulnerability was classified in five groups from very low to very high. By comparing the results of these two models, it was revealed that these models had a similar vulnerability but they had a difference in which based on AHP model, the regions with very high vulnerability have little fragmentation in contrast with TOPSIS model. Therefore, according to AHP the most fragmentation was occurred in regions with low vulnerability. While, based on TOPSIS, the regions with average vulnerability have the most extension. According to Both models the most vulnerable areas were in the north of Sanandaj city.

rid and semi-arid regions of the world is mainly characterized by lack or little amount of precipitation as well as irregular tempo-spatial distribution of annual rainfall and highly evapotranspiration. On the other hand, recent permanent drought in East Azerbaijan province has led to a reduction in available water resources, a sharp drop in the groundwater levels, Urmia Lake receding and drying and increasing saline lands surrounding the Urmia Lake. Also the orchards and farm lands that seriously depend on groundwater level have been indiscriminately and disproportionately developed related to the climate condition. Therefore, modification of agricultural patterns is the best way to efficient water use in agriculture and is considered as the only practical solution in relation to the sustainable development of agriculture. This study was conducted in order to determine the appropriate area for growing pistachio orchards and replacing it with second and third order of gardens.

IntroductionIn the present research, the traditional water system and the way of obtaining and exploiting water resources in the past have been studied. To verify the existence of this traditional system in this city, archival documents, which had a significant impact on our understanding of urban development and the water supply network, were referred to. It is the commencement of our understanding of how to use traditional canals and waterways, the signs of which can be recognized in the ancient context. Consequently, the key question was raised as follows: what effects did the water supply network and the traditional water system have on the formation of the spatial organization? In response to this question, this hypothesis was shaped that it seems that the water supply and water distribution network in the city of Sonqor affected the formation and cohesion of neighborhoods from the middle Islamic period onwards. Data and methodThe current research is applied research regarding the purpose of the research method, the data collection method is a case study, and the non-contact method of electromagnetism method has been subjected to a field survey. This method was used to determine the movement of water underground and to locate and prove the existence of springs and alluviums. The determined points of springs and canals as the studied community have been evaluated in a descriptive and non-experimental format. Collecting information from library and field methods and in a non-experimental descriptive format based on documents and ancient evidence, springs, aqueducts and reservoirs were located and identified on the maps using the analytical-descriptive method.Discussion and conclusionAccording to soundings done on the identification points of the springs outside the city, which were checked within a radius of 2 km from the city, the slope of the water flow of the springs and canals along the canal, waterways and streams based on the roughness and height position in the depth of the ground or the ground surface was calculated and measured based on the height of a place above the sea level. The result was that on the eastern side of Danesh Sara and Shah Murad Kariz; on the north side of the Chaman Pashm kariz; and on the western side with Malik kariz and Dara Maleh valleys, the depth of the water flow in the ground is between 3 and 7 meters. Underground water flows from the north of the city to the south of the city, with the slope of the land between 1.5% and 2% of natural alluvium and the water of springs and canals to the lower parts of the city. On the east side of the city, water flows downstream from the Daneshsara aqueduct with a slope of 2%, in the center of the city with a slope of 1.68%, and on the west side of the city with a slope of 1.5%. This procedure can be proven in the vicinity of the northern aqueducts compared to the southern aqueducts and in comparison to the height above sea level. Out of the total number of springs and aqueducts in Sonqor city, 17 points were identified and investigated, out of which 6 points had ancient remnants, and the rest of the studied community were located in the urban context.ResultsFrom the geology and natural geography point of view and according to the field and non-contact EM investigations, the collected information designates that the city of Sonqor was built on alluvial layers. These alluvial layers have changed the earth's surface water path over millions of years. This change has caused the alluviums in the northeast to be higher than the alluviums downstream in the south and southwest. Water appears at fewer than 5 meters on the alluvial layers and is easily accessible to the early inhabitants. Man can build his residence near natural springs by relying on communication and interaction with nature.Consequently, in response to the research question, it can be said that when the city of Sonqor was formed, the most important component that was taken into account was the natural springs that appeared on the alluvial layers in the city of Sonqor. Water harvesting from this spring was done easily. The spatial organization and architecture of Sonqor city are also formed according to the concentration and locational focus of the springs.

To identify and detect the frequency variation trend of Iran’s pervasive and semi-pervasive frost days in the current research, minimal daily temperature data of 663 Iranian climatology and synoptic stations were acquired from Iran Meteorology Organization during the time interval between 1962 and 2004 for October to April months. Following data acquisition, Iran’s isothermal maps for each day starting from 1.1.1962 until 31.12.2004 (9116 days) were prepared using Kirging interpolation technique in order to construct the database of the county’s minimal temperature. In the next step, frosts were classified in three types based on a spatial principle: pervasive frosts (simultaneous occurrence in more than 65% of Iran’s surface area), semi-pervasive frosts (simultaneous occurrence in 25% - 65% of Iran’s surface area), and local frosts (simultaneous occurrence in less than 25% of Iran’s surface area). Then, frequency of pervasive and semi-pervasive frost days were analyzed in three scales including monthly, seasonal, and yearly using two estimation techniques of slope SENSE and linear regression.
Results indicated that frequency of pervasive frosts in Iran held a statistically significant decreasing trend in December and January months, during winter, and also, in annual basis. But, for semi-pervasive frost days, it was observed that variation was significant only in January having a positive trend. It signifies that number of days with semi-pervasive frost increased during the 43 years under study. Therefore, number of semi-pervasive frost occurrences increased while number of pervasive frost occurrences decreased in January. The same rule holds for other scales i.e. monthly, seasonal, and yearly basis.

The aim of the current study is, which uses a descriptive-analytical tool, is to investigate the factors hindering the usage of sprinkler Irrigation systems among farmers in Ravansar and propose practical ways to reinforce these systems. The sample included those farmers who used sprinkler Irrigation in Ravansar (N = 190). Factor analysis was performed for analyzing the collected data. The results indicated that use of these systems among farmers in Ravansar is more due to the physical issues rather those theoretical issues. Physical variables of performance system issues (26/612), the agricultural characteristics (22/868), behavioral issues (19/997), and environmental factors (16/492) were found to account for the 82/969 percent of the variance. Additionally, theoretician factors of performance system issues (31/874), personal (19/980), technical (15/236), and technical incongruence (7/921) accounted for 72/711 percent of the shared variance. The findings also indicated that providing financial (bank) facilities in form of loans was the best way to implement these sprinklers Irrigation systems. Most of the participants (77/9 %) found the practical solutions proposed by this study to be satisfactory.

Iran is located on the world’s Sun Belt; therefore the required energy of many parts of the country can be generated through photovoltaic systems. One of the most salient characteristic of renewable energy with regard to its conversion and usage is its dependency on geographical location as well as numerous contradicting factors. A suitable site for solar farm must fulfill a series of economic, conservational, climatic, geographic and demographic considerations simultaneously. This research uses multi-criteria decision making (MCDM), fuzzy principles and GIS tools to evaluate the optimized place of photovoltaic solar power plants in Iran. To achieve this objective, three approaches are considered, namely: TOPSIS (Technique for Order Preference by Similarity to Ideal Solution), Sugeno-type Fuzzy inference system and fuzzy TOPSIS. After obtaining experts’ opinions, site selection steps have been taken in two main steps: first, the deduction of impossible points (constrained); second, the calculation of location’s potential using raster analysis. The comparison of the above methods showed that Fuzzy TOPSIS؛ from the perspective of continuity and involving elements؛ had better performance. TOPSIS Method 14.71% and fuzzy TOPSIS 18.33% and Sugeno 20.52% of the total area are considered as suitable area for the construction of solar power plants. All three methods had similar results. The priority of country’s sections for locating solar farm locations are estimated as, Narimanshir, Nobandegan, Farajhiand, Bahmanpour, Shibkoh and Gavbandi through all methods with subtle variations.

The first prerequisite for the success of the rural researches is correct understanding and suitable perception of the needs of local communities. The part of the country's rural researches includes thesis and dissertation of students in geography and rural planning. In this article, we examine the relationship between the thesis and dissertation with the needs of rural communities and try to provide a model for rural researches in Iran. The methodology is descriptive-analytical which was conducted to combine two documentary and survey methods. The statistical population includes student population (N=161) and faculty stafs (N=20) in the field of rural geography and planning at three universities (University of Tehran, Shahid Beheshti University and Tarbiat Modarres University). Research results show that the majority of academic advisors in theses/dissertations believed that there was a relationship between the subjects selected for the research and the needs of rural communities but the results of the most important factor in selecting theses/dissertations’s subject showed that students have less attention to the needs of rural communities. Financial constraints (financial problems of students), weighing 0.249 was the most important limitation of the students to choose issues on rural communities’ needs. Accordingly, the proposed model for carrying out rural research in Iran was presented.

Introduction With the increasing development of human societies, urban societies have also undergone many changes and complexities. This transformation and complexity encompasses all aspects of human life in cities. One of the most important categories in urban development is having a dynamic economy. Parsabad city is one of the a few new cities in Iran that has been created under the influence of this theory and the category of comparative advantage of regions in the second quarter of the present century. The city was established in line with the development plan of the Moghan Plain Civil Enterprise in 1953 and in order to exploit the fertile lands of the plain as a new and fledgling city. Because this development was done rapidly in fertile lands .It is considered the best agricultural lands in the Moghan plain, and with the expansion of the city, the agricultural lands around the city were being reconstruct day by day, causing changes in the landuses The study of physical, economic, social and biological conditions indicates the development of the city and changes in its land use. Since the use of traditional methods to determine urban development and land use changes is very time consuming and costly, so using multi-time satellite images and digital maps and a variety of models can model urban development landuse changes and simulated and examined the relevant implications. The purpose of this research is: Assess using quantity models in Predicting urban development trends and land use changes. Assess the future pattern of urban development and land use in Parsabad city. Methodology This research with respect to type of purpose and nature were classified applied and descriptive-analytical research. The instruments used in this research are Landsat satellite images of TM, ETM +, OLI sensors included in 1989, 2002, June 2015 period. For analysis of images , ENVI 5, IDRISI SELVA, ARC GIS software were used . All classification options in ENVI 5 software are situated in the Classification menu. The unsupervised and supervised classification methods were placed in unsupervised and supervised option. In this study, we used the supervised classification method for classification. Results and discussion In general, the process of simulating urban development and land use changes are categorized in three general stages: Create a transition matrix using Markov chain analysis • Create competency maps for each land use class using Multi-Criteria evaluations (MCE) Weighted Linear Combination (WLC) • Accomplishing the transition matrix from Markov chain analysis and spatial fit maps of land use classes and land use / land cover map for simulation automated cells-based. To obtain the transition probability matrix, we use the user map which obtained from satellite images from 2002 to 2015. The weighted linear composition and multi-criteria evaluation method were used to create spatial fit maps for each land use. These criteria was considered in the form of factors and constraints. Factors: distance from water levels, distance from city center, distance from road, distance from constructed lands, landuses, slope to percentage. Limitations of these criteria were e constructed lands, water levels and its 50-meter area. For simulating the land use map of 2028, the land use map of 2015 has been used. All the simulation steps have been done in IDRISI SELVA software environment using markov-ca model. In 2028, the amount of constructed lands increased by 400 hectares, instead, the use of farm lands decreased by 410 hectares. As presented in figures the greatest decrease and change of landuse in this period related to farm lands, and the barren lands decreased approximately 20 hectares by Maid, Exploiting from forest and water land use show a relative increase. By comparing the map of 2015 and the simulated map for 2028, it can be concluded that the development of constructed lands have been unsuitable to barren and farm land use., Also with the development of constructed lands, the use of farm and barren lands area, especially farms, has been reduced. Conclusion With respect to urban development and land use changes in Parsabad city, it can be concluded that: In response to the first question, the study of land use maps of previous periods showed that during the last 26 years, the area of barren lands and surrounding farms of city has been reduced. This amount of reduction has been more to the benefit of urban land use so that the land use area of urban land has increased to278,567 and 820 hectares in 1989 , 2002 and 2015 periods, respectively. In response to the second question of the research, the main level of land use change in the coming years will take place on the outskirts of the southwestern part of the city, including the residential towns of Fajr, Farhangian; And the future development model of Parsabad city is somewhat out of the scattered state and will be done more on the surrounding agricultural and barren lands and without use inside the city, especially in the southwestern part of the city. It was clear that during the last 26 years, the most changes and urban development has taken place in this part of the city. Agricultural lands in this part of the city gradually become to barren land use and eventually changed to urban landuse; the fact that from 1989 to 2015, the area of the city has been increased by 70 hectares only in this part of the city.

Introduction In rural areas, tourism as one of the most popular forms of tourism can, lead to economic growth and the diversification of rural activities, on the other hand, by attracting human resource surpluses, to create employment and generate income for villagers, thus giving them an opportunity to develop All-round. In recent years and in line with tourism development in rural districts, study of the effect and action of rural tourism has been a productive domain for interdisciplinary research. One of the subjects is investigating the tourism effects on empowerment of rural societies. Accordingly, aim of the study is to investigate the role and the effect of rural tourism on empowering of local society in social, cultural and economic aspects in villages of central district of Natanz. Methodology The study is an applied research and from the point of view of the method and nature, it is a descriptive-analytic one. The method of collecting the data was a combination of library and field methods. Data collecting tool is a researcher made questionnaire including 85 general and special questions. Validity of the tool is face validity and was confirmed by experts and also was structural by means of factor analysis and its reliability was set by Cronbach’s Alpha about 0.854. Statistical population of the study were the rural inhabitants of central district of Natanz (N=4046). The sample size was 354 people according to Morgan table. Statistical analyses were conducted by SPSS software, Binominal tests, chi-square, Mann-Whitney, Wilcoxon, T student, Fisher, Manova, Anova, factor analysis and cluster analysis. The Maps was made by ArcGIS software. Results and discussion The results show that the average of general empowerment in tourism villages with amount of 3.34 is in a higher place than non-tourism villages with general empowerment average of 3.15. The results of T-test, according to the average amounts of the sample 3.48 and 3.34 for cultural empowerment and social empowerment respectively and high amounts of T student 11.574 and 8.280 which were the result in zero for the assumed significant level of zero, confirm the effect of tourism on cultural and social empowerment in level of 0.05. Level of significant of 0.155 for tourism effect on economic empowerment aspect, has denied the effect of tourism on this aspect. Also, the statistical amount of empowerment comparison in Fisher test is 5.967 with freedom degrees of 1 and 298 in form of triple aspects among tourism and non-tourism villages. Hence, the difference between general empowerment among tourism and non-tourism villages is significant. Zero amounts of significant level for Wilcoxon tests among empowerment aspects show that these aspects have significant differences two by two. Consequently, cultural empowerment with average of 3.484 is in the highest level and economic empowerment with average of 2.98 is in the lowest level. The results of clustering the variables demonstrate that cultural and social aspects are closer to each other based on conceptual theme. Conclusion According to the findings, empowerment status is better in tourist villages. In general, cultural empowerment is most and economic empowerment is the least. It seems that the situation with regard to economic empowerment seems not to be favorable; especially the investment empowerment has a bad situation. In fact, the presence of the tourist, although beneficial in terms of employment and income, was not as effective in the field of investment (as a more radical variable).The lack of meaningful economic effects of tourism on the part of the local community is due to the fact that the villagers expected to receive direct and tangible income from tourism and less attention to its multiplier effects. In any case, social and cultural empowerment in both types of villages is at a higher level than economic empowerment.According to the results of the research, setting up and providing legal support for private sector investment in tourism development in the studied villages, Development of basic skills for employment in the tourism sector in cooperation with the technical and vocational organization with the aim of creating job opportunities and income generation, Training on entrepreneurial skills with a native-oriented approach, Teaching social and communication skills to communicate with tourists and influential institutions in tourism, Recognizing and introducing the attractions of rural tourism using mass media, social networks, Cyberspace and interaction with tourism agencies, supporting cultural and local patterns and values as the main capital for tourism development, Increasing the knowledge and knowledge about tourism and holding local and regional ceremonies and celebrations with a tourist attraction approach can deepen the tourism impacts of the study in the study area and lead to rural development.

Introduction Recently, issues raised by changes in precipitation, especially problems brought about by floods and droughts, along with the environmental effects of diminished rainfall, have underscored the importance of precipitation studies at different temporal and spatial scales. Due to the pervasive impact of precipitation parameter in various urban, industrial and agricultural fields with respect to water supply, the identification of fluctuations, changes and precipitation structure is of particular importance, especially in arid and semi-arid regions. The similarity feature in climatic variables allows the use of fractal geometry and analysis of temporal and spatial changes. Accordingly, the use of fractal geometry in predicting the behavior of many natural processes, including precipitation in different regions, has a special place. The goal of this study is to investigate the structure of different time periods of precipitation in Shiraz synoptic stations to explore changes and determine the spatial position of precipitation in the stability and instability period. Methodology In this study, daily precipitation data was received over a period of 58 years (1956-2013) from the Meteorological Organization of Fars Province to investigate the structure governing precipitation parameter. Then, statistical deficiencies were corrected by restructuring using difference ratio and linear regression. The methodology and algebraic logic of calculations in this study are such that in the first step, research parameters are arranged from minimum to maximum in an ascending order. Then, based on the triangular threshold coordinates(2Π), the minimum and maximum were extracted based on linear structures of the desired criteria and algebraic mathematical reference was conducted using Relation (1). Relation (1) F (x) = Then, in order to apply the fractal structure by applying the criterion for mathematical reference using Relation (2), the real structure of the desired meteorological parameters was obtained. Relation (2) Y = m2 × sin (1/m) Finally, by overlapping the output charts of the actual structures and the classical structure of the fractal (Figure 2) in the algebraic ranges of -0.4 to +0.4, the algebraic process of each climatic parameter was evaluated separately. Results and discussion In this study, based on the results, in addition to the daily analysis of the governing structure of precipitation over a 58-year period (1956-2012), which covered 21185 days, the governing structure along with the analysis of equilibrium dynamics of structures and its functions in three time periods (three 20-year periods) of different daily precipitation were also examined separately. The first period began in January 1, 1956 and lasted for 7065 days. The relevant calculations were performed on the data derived from the first period, which based on the findings of this study, precipitation in Shiraz''s synoptic stations do not follow the fractal logic in the first period by applying fractal algebraic structures, Also, in the second period, similar to the first one, the precipitation structure does not comply with a particular fractal logic. In other words, the logic governing precipitation parameter during the first and second periods changes from equilibrium to non-equilibrium. However, unlike the previous two periods, the fractal logic is followed in the third period. Conclusion The self-similarity feature in climatic variables allows the use of fractal dimension and analysis of temporal and spatial changes. Accordingly, the use of fractal geometry in predicting the behavior of many natural processes, including precipitation in different regions, has a special place. The goal of this study was to investigate the structure of different periods of precipitation in Shiraz synoptic station to identify changes and determine the spatial position of precipitation structure in the period of stability and instability. The behavior of meteorological parameters in various parts of the world is a function that never follows uniform algebraic structure. Therefore, the analysis of complex systems and changes in nonlinear climate parameters using chaotic, fractal and fuzzy concepts offers a suitable way to understand the equilibrium state and dynamic analyses of climate fractal changes. The results indicate the dynamic transition of this time period from non-equilibrium to equilibrium. Therefore, according to the three time periods, the equilibrium dynamics of the daily precipitation structure approaches fractal structure.

Introduction Along with geotourism,the scientific community is still in search of answers suitable for the purpose, why travel to the geotouristic areas, interests and motivations, needs and desires and demographic characteristics of geotourists. On the other hand, there are different interpretations and the plurality of opinions in this regard, some confusion in the literature is provided. Materials and Methods This article attempts to analyze and the expression of a range of dimensions and characteristics of a geotourist and collecting and providing comments and suggestions in the literature, Certain information from geotourists for researchers and practitioners in the field provided. The research method is descriptive content analysis. During this study, the position and status of theoretical foundations of geotourists have been described in terms of the nature and scope of geotourism. Discussion and Results Everyone, as the executive or audience of geotourism, is obligated to observe all its principles and dimensions. Minimizing the consequences, negating environmental and cultural awareness, creating positive experiences for visitors and hosts, attracting direct financial support for safeguards measures, creating financial rewards and empowering local peoples, enhancing the political, environmental, and social environment of host societies, supporting Citizenship rights are the most important of these principles. On the other hand, one of the goals of geotourism is to teach geosciences. Given the challenge, designing tools and providing solutions that can combine these two, namely, leisure and training, is necessary. Attention to the typology of geotourists leads to a better understanding of the dimensions of geotourism and contributes to the development and marketing of geotourism. It also provides some insight into the choice of tourism destination and the creation of a competitive atmosphere for these purposes. The experience of successful geotourism depends on the needs of the tourist and, in this case, it is more probable to re-visit geosite. Having a set of phenomena and tourist attractions with geological, geomorphologic, biological, heritage and cultural features is one of the most important features of each geotourist site. Therefore, offering a diverse set of attractions that is known in the literature of geotourism as "ABC[1]", and covers non-polluting phenomena (geological and geomorphological), living (animals and plants), and cultural (artificial attraction), from geotours side is necessary for geotourists. The development of geotourism should not affect the conservation of geotourist sites. Therefore, developers and land managers must, in any way, establish a balance between the conservation and development of geotourism. In the meantime, creation of geotourist training ground is one of the important tasks of geoscientists working in the field of geotourism. Undoubtedly, it is necessary to use simple and adaptive instruments for the geotourists to explain and teach geology and geomorphology for geotourists. This paper attempts to present an image of geotourists and their characteristics by reviewing resources and collecting globally written documents. The increasing trend of interest in visiting geotourist sites, increasing geological and geomorphologic information, visiting diverse cultures, enjoying outdoor activities, and settling in simple residences, in spite of the persuasion of tourists to geotourism, led the geotourists to take individual trips to instead of participating in the tour group. Perhaps because of this, the lack of such tours in Iran and even the world, or if they exist, will not meet the needs and aspirations of geotourists. Conclusions The results showed that the real geotourist is one who in order to geotourism purposes and proportionate to the nature and scope of it, protect and support the five key aspects of the geographical features of the area, the environment, culture, aesthetics, science and education and well-being of local people. This paper tries to provide researchers and practitioners with a geotourism perspective with comprehensive analysis of the dimensions and characteristics of a geotourist and the collection and presentation of ideas and suggestions in the subject literature. [1]-‘ABC’ attractions including Abiotic (non-living features such as geological attractions), biotic features (including fauna and flora) and Cultural (including built attractions).

Introduction
In today’s world, the growing trend of urban population and urbanization process on the one hand, and the need to maintain land located in the suburbs and valuable natural area and the need to save the land on the other hand, has put high-rise construction and dense urban development on the agenda of the urban management. The provision of housing and the issue of population housing have always been the most significant factor in the nature and objective of such planning, and may have marginalized considerations and observance of various physical, social, cultural and environmental criteria. Because of factors such as the reconstruction of the ruins of the eight-year war, the process of migration from rural areas and other cities of West Azerbaijan province to this city, at a time, the city of Urmia first began to develop horizontally through numerous changes in urban uses, after that time, due to huge costs, the existence of natural barriers from a geographical point of view, the inability of the local executive body in providing infrastructure networks, the tendency to develop high-rise buildings within the urban management setting and consequently among the private sector becamemore powerful. The process of dense construction of Urmia began more or less in the late 1990s, and since then, the city of Urmia has been the bedrock for the construction of high-rise residential buildings in high and relatively high areas; and during this period, natural resources and barren lands underwent land use changes and dense development; consequently, the development of high buildings, apart from social and cultural inadequacies, has imposed congestion and traffic problems in the alleys, as well as the inconsistency, heterogeneity and ugliness on the city.
Data and methods
This research is of cognitive type in terms of purpose, and is of evaluation type in terms of method; it is of cross-sectional in terms of time; and, is quantitative in terms of data type. Primary data were analyzed in SPSS software, specifically through using one-sample t-test and Friedman test. The statistical population of the study includes citizens living in district 1 of Urmia Municipality, and based on Cochran's formula, the sample size has been calculated and determined to be 384 people. In order to collect data, a questionnaire was prepared based on simple random sampling method in the number of the sample size, and it was distributed in the study area. And its face and content validity has been estimated based on the purpose of the research through consulting with professors and experts, and its reliability was estimated by Cronbach's alpha test to measure the internal consistency of items, and was found to be 0.81.
Results and Discussion
Nowadays, the need for a high-rise construction strategy is more apparent due to the increasing population growth and land constraints. High-rise buildings, as the result of technological advancement, can increase pollution due to the negative environmental consequences associated with high population and building densities, if not properly controlled and supervised. In this study, according to one -sample t-test, all four dimensions include a moderate to high status (social: 30.4; economic: 28.7; environmental: 26.8; and physical: 45.6). According to Friedman test, the reason for the moderate to high social status is the proportionality of the security situation and the low rate of conflict, but the sense of belonging and life suitability in the units is not very satisfactory. The above-average economic status is due to the profitability in construction and the existence of seasonal jobs, which is associated with a service-oriented economy in strict 1 of the city of Urmia. Regarding the environmental dimension, the relatively good health status has taken an average to high score, and at the same time the quality of waste collection in strict 1 of Urmia is appropriate. But noise pollution is on the rise in the strict. In terms of the physical dimension, the proper quality of the water, gas and telephone network has given it a moderate to high status. But the physical dimension of district 1 has been problematic for high-rise buildings in cases such as neighborhood , emergency stairs, building strength, impact on street congestion due to shortage of parking areas.
Conclusion
According to the criteria studied and what is highlighted in the principles of high-rise construction, more density of the city leads to the lower transportation, while the case study in this research is one of the busiest parts of the city in terms of traffic, daily and night movement of personal vehicles. Despite the possibility of better and more use of urban lands, district 1, which has a higher slope and is at higher altitude comparing to the other areas of the city, does not have much power and possibility to get natural light, and has increased shading. It has inevitably failed to achieve urban sustainability. It can be acknowledged that despite the expansion of high-rise buildings and the vertical growth and density of the city, the location allocation of these units has not been done properly; and in the field of construction, the obvious principles such as height proportion, facade proportion, neighborhood, distribution of facilities and services, etc. have not been observed, and this issue has distorted the urban landscape. In addition, the lack of infrastructure such as multi-storey parking areas and the lack of parking in the buildings have contributed to the congestion of the streets. And all of theses issues are due to not following a distinct and standard pattern, and the process of transformation of the district has been mostly subjective in terms of high-rise construction.

For tourism development, existing of tourist attractions is not enough, but developing of suitable tourist facilities is neccessory. So, according to the importance of tourist facilities in attracting tourists, especially to suburban places, the present study investigate the status of the tourist satisfaction of tourist facilities in Chak-Chak in Ardakan county. So, 106 number of tourists were selected in Norooz 2013 by Convenience sampling method. To gather data, library method, field method as well as tourist questionnaires were applied. Gathered data analyzed with descriptive (number, frequency, percentage, mean) and quantitative (T-Test, One-Way Anova, Pearson correlation) method. Regarding the first hypotheses, the findings indicated that tourists believe that the status of tourist facilities is very inappropriate in Chak-Chak and tourist satisfaction in all these three dimensions is low and very low; as a result, the first hypothesis was confirmed. The results indicated that the second hypothesis reject relatively, so that the total findings indicated that Chak-Chak tourists’ satisfaction is only significantly different in about religion variable. The results suggested that tourists’ satisfaction is not significantly different in all variables, except job position. To test the third hypothesis, the results of relationship analysis of tourists’ satisfaction and social-economic variables revealed that Chak-Chak tourists’ satisfaction has a significant relationship with all variables (gender, religion and job position) except age. So in general, the third hypothesis was relatively confirmed. In all, low level of tourist satisfaction indicate that the planning system ignored these places, whereas need more attention

IntroductionPublic art has followed a new trend in urban spaces in recent years, so that cities invest highly in the design and implementing of public works of art and improving the visual quality of urban spaces, since it is effective in creating good urban spaces and making the city attractive and memorable. It also encourages people to communicate with works of art and each other. Although public art as an art integrated with the public space of cities is not a new concept, many changes have been created in public art and it caused the creation of various types of public art in most cases from a purely static art to a dynamic and interactive art. This article aims to investigate the effect of public art in urban spaces on promoting the perceived vitality of young people. Despite the importance and role of public art in the quality of urban public spaces, studies conducted in the area of public art have not paid much attention to the effect of different types of public arts in public spaces on vitality of people, especially young people. Thus, this study was conducted with the aim of answering the question of “which type of public art has a greater impact on promoting the perceived vitality of young people in urban spaces?”Data and MethodsThe present study is a qualitative-quantitative (mixed) study conducted as a survey. In the present study, visual approach and image reading were used to collect information. Visual research is a term that includes methods based on data collection and analysis of them through designing, painting, photography, film, or video images. In this article, public arts and interactive arts were divided into different types based on theoretical foundations and research literature and an image was selected from each type of art and through an online questionnaire was submitted to the participants and they were asked to express their level of vitality from watching that work of art in urban spaces on a 5-point Likert scales. This questionnaire was designed and sent to the target population through cyberspace applications. Since the target population of the present article was young people, the sample was selected among the students of Tabriz University and the students of Nabi Akram Institute of Higher Education in Tabriz in the second semester of 2020-2021. To determine the sample size, Cochran's formula with an error level of 5% was used. According to the number of students in these two universities (27000 people), the sample size of 379 was selected. After sending the questionnaire to nearly 380 people, 144 people completed the questionnaire. In this research, both art and architecture students and non-art and architecture students in both bachelor and master levels were surveyed.Discussion and ConclusionThe research results revealed that among different types of public arts in urban spaces, sound and digital arts such as musical fountain, and the integrated art embedded in the elements available in space such as wall relief in the body of the building and the art appropriate to the site, such as plants formed in parks, regardless of the three criteria of gender, age, education and field of study, are accepted by all young people and increase vitality, but abstract static art is less welcomed by young people. Among the interactive arts, dynamic-passive interactive art and static interactive art obtained the highest score in terms of creating a sense of vitality among young people, and in contrast, dynamic-dynamic interactive art obtained the lowest score. Art related to public and local culture caused the highest vitality among male young people and young non-art and architecture master students, and digital art caused the highest vitality among females and bachelor art and architecture students. In addition, among non-art and architecture bachelor students, two-dimensional applied art obtained a relatively high score.Results The results show that creating static works of art is not effective in designing cities and using public art to create a sense of vitality in urban space and young people show higher tendency to dynamic work of arts. Also, interactive works of art are more acceptable than non-interactive types, and urban planners should pay attention to this issue in embedding works of art in urban spaces and take right decisions and actions to increase presence, interaction, and vitality among young people in urban spaces. Also, the use of modern technologies and creativity in the artistic design of cities is one of the requirements for adapting the urban space to spirits of young people.

Scientific capacity is one of the key factors contributing to sustainable development in a country. The development of scientific capacity requires improvement in scientific publication and productions. This study aimed to investigate the publishing condition of the articles in the Journal of Geography and Planning during 2010-2014. The study adopted a descriptive method and survey design. The results showed that the Journal has published a number of 201 articles over the studied period. Of the published articles, 87% were co-authored by multiple writers. The co-authorship was mostly in the form of intra-institutional contribution. The mean score of collaboration degree was 0.87 while the mean score of collaboration index was shown to be 2.53, which indicates strong co-authorship relations among the Journal contributors. The highest collaboration percentage was observed between two and three authors. With 97 articles, the authors affiliated with TabrizUniversity published about 50% of articles in the Journal. Thus, TabrizUniversity was the most prolific institution.

Iran is located on the world’s Sun Belt; therefore the required energy of many parts of the country can be generated through photovoltaic systems. Nowadays, with the increasing growth of energy consumption, the tendency to use renewable energy and specifically solar powers is rising. Within 2000 to 2007, world energy production increased 10.3 percent per capita (Department of Energy, Iran).This consumption increase in 2030 reaches over 48% and even 60% in 2000. However, disadvantages of fossil energy led international community to use new types of renewable energy. Among the renewable energy forms, solar energy tends to be the cleanest energy and considering potentials of the selected sites, is can be deemed economical, as well.

Introduction Erosion involves the retreat or advancement of the coastline, is the one of the recent problems of communities along the coast and the existing infrastructure located near the estuary system. Environmentally, coastal areas are of great importance and value due to their sensitive and productive ecosystems. Short-term or long-term coastline changes are important in the situation and geometry of coastlines and coastal management. Awareness of coastline behavior helps to manage beaches when designing and constructing coastal facilities and determining the safe margin of the coast. This article tries to modeling the changes in the coastline of East and West Bandar jask(southern Iran) in a timespan, a step towards coastal management for the planning and operation of facilities of Jask Port, which can be follow the future development of the area. Methodology The study area is part of the coast of Jask city located in Jask county in southern Iran. For this purpose, the extent of coastline changes to determine the boundary line between land and water was examined. To be more precise, spectral operators were used in the Arc map environment and Landsat satellite imagery; the next step was to polygonize the shoreline according to the fixed landline on land. In addition, Google Earth satellite imagery was used to examine and mark some case-by-case changes, such as cape changes in the western part of the port of Jask and so on. Results and Discussion The dynamics of coastlines and their variability (affected by lithology and wave activity), the shape of coastlines and their effect on erosion and location of coastal sediments, resources and location of sediment accumulation and hydrodynamics of areas close to coastlines, the intensity of seasonal winds and its role in transmission Sediment transfer and erosion mechanisms, and ultimately, human activities, are among the factors influencing coastline changes. The shape of the shores was examined using the Hausdorff-Pesikovtch method. Accordingly, the rate of change in the area of polygons on the east coast (progress) is higher than on the west coast (retrograde). The reason for the progress on the East Coast could be the construction of new piers, tidal performance, the shape of the beach and how it is positioned against the waves. Overall, Oman's beaches are uplifted, which could be the reason for the retrograde; however, the drying up of the coast in order to build piers and breakwaters has led to the advance of the coast. conclusion Prove the existence of progress on the east coast due to the construction of three new piers (after 2006) and the presence of retrograde on the west coast due to the existing natural mechanisms of the region such as the uplift of Oman coast, is the most important finding of this study. The shape of the beach and the way it escapes from the waves due to the prevailing wind direction (from the southeast) on the east coast has intensified the effect of the human factor.
