In recent decades, cities have grown organically and urban areas in a short time have been several times its original size and city development has been the forms of the individual components, without planning, uncoordinated that urban sprawl pattern is the main feature. Urban Smart Growth cities were developed for deal with problems of sprawl. The case study is Maragheh city. The research method is descriptive and analytical. In this paper, the capacity of Maragheh, using the development from within the main principles of smart growth is about the sprawl, is marked. Indexes such as population density, rate of open space, building quality, access and permeability, compressibility, etc. are used. Neighborhoods with using Analytical Hierarchy presses (AHP) to prioritize and ultimately the level was estimated for each of them. Results show that in 1392 the gross population density of 59.3 persons per hectare is which is considered very low density and On the other hand there is a lot of undeveloped land, 333 hectares, Uses of unconventional urban, and the average per capita level of infrastructure per person is 162.3 square meters. With this description, using the principles of smart growth and in particular, the principle of development from within and Suitable density, Building on wasteland and etc., sprawl can be prevented the sprawl.

Settlements physical and functional affecting from the natural environment is obvious and undeniable. In this regard numerous factors play a role and by that location, building, physical development, population absorption and … in human settlements formed differently. This study aimed to analyze the spatial pattern of settlement in Gilan Province, has been formed under the influence of natural factors. In this way the main questions facing the study, is the effect of natural factors on the spatial pattern of settlement in the province. Gilan settlement system based on the last census has 2990 points, that all of them were considered in this research. The research method is descriptive- analytic and in it the documentary and spatial statistical analysis in geographic information system with the spatial autocorrelation analysis based on Moran's I index were used. The results indicate that although the settlements of Gilan province in terms of population is not concentrated but from all variables point of view (height, slope, slope aspect, precipitation, temperature, evapotranspiration, distance from surface water and natural vegetation) high clustering were observed in the distribution of the settlements in the province and spatial correlation of all the variables with the spatial distribution pattern were statistically significant

One of the main strategies to achieve the forestry objective and to minimize the environmental crisises, planning use of the forest by taking a natural ability is for users desired. In this research, using the Analytic Network Process (ANP), the criteria of ecological, economic and social, in the BOCR structure frame work in forest habitat of Jouzk-darekhsh (Northern Khorasan) were evaluated and prioritized. The results showed that the sub network of profits with a total weight of 0.55 is located in first priority and sub network of risks with total weight 0.07 in the last priority. In sub network of earnings, revenue increase was in the first priority and the first priorities of the risks sub network also was allocated public acceptance. Among the strategic criteria also social criteria were to assign high weight (0.49) and then economic criteria weighing 0.31 and ecological with weighting 0.19. Finally the results showed that ecotourism options with a total weight of o.62, protection with a total weight 0.19 and option exploitation of ancillary products with a total weight 0.18 respectively in the priority first, second and third. According to the results, the forest can be pushed to the client-side tourist undoubtedly made an impact in preventing the destruction of all the fields, employment and public participation, public participation and respect for the policies followed by the increase in the residents of the area, helping to prevent migration to urban areas and overall development of villages surrounding the forest area will be followed.

Density with increased population and disregarding social, economic, spatial-physical and environmental effects caused some problems that attracted the attention of urban planners and managements in metropolises such as Tehran. This problem is attention by urban planner and urban management. The proper framework of density (population density, high density, and land use density) at nine areas of 4 district of Tehran municipality seeks in this paper. And effect of density on earthquake vulnerability is study. This is an applied research; and research scrutiny methods are correlation, multivariate regression and fuzzy models. Data collected by documentary and survey methods. Research objectives include identifying density status (population, high, and land use) and discovering the relation between density level (population, high, and land use) and earthquake vulnerability and finally analyzing the effects of increased density (population, high, and land use) on earthquake vulnerability at municipality of Tehran (4 District). Research results show that it is necessary to consider three types of population, land use, and high densities in studying urban density. Moreover, fuzzy approach in urban density data normalization is one of the best approaches in urban vulnarability. In this regard, using fuzzy simple additive weighted method (FSAW) revealed that 7zone (density rank: 6.43), 8zone (density rank: 7.46), and 9zone (density rank: 8) at 4 district of Tehran obtained the lowest density rank; whereas, the highest mean density rank attributed to 6zone (density rank: 1.46) and 5zone (density rank: 2.48), respectively.

Uneven and unequal distribution of public land has been one of the consequences of libertine urban growth in the recent decades that has led to an unbalance in the distribution of urban public lands. This has had enormous implications, one of them being the lack of equal access to municipal services for citizens. Due to political and political developments in Ardabil during the recent decades this city achieved a massive physical growth so that this libertine physical growth has led to an unbalanced distribution of public land and caused forming a bipolar wealthy and deprived city. Accordingly this study aims at investigating and analyzing the public land distribution manner to evaluate the distribution of public utility and to grade and determine wealthy and deprived urban regions. This study employs descriptive-analytical method and essentially could have applied nature. To collect data the library method was used. To achieve study objectives two hypotheses were designed, in order to test the first one spatial autocorrelation analysis tools and the nearest neighbor index and to test the second one Kernel density function were used.

The growing urban population and the absolute rise in the rate of car ownership have caused a number of problems in the smooth flow of traffic in the cities. Better public transport system, especially the subway system, which is opened and expanded in some Iranian cities would help ease traffic congestion. While introducing Tabriz subway system, this article evaluates the conditions of subway stations according to twenty four indexes which are provided by hieratical analytic model. The article shows that 29 Bahaman and Shahriyar stations mark the highest point in furniture quality variable while Khayyam station comes last. Station four has the most immediate access to emergency aid while station 6 has the least. Land uses around stations 2 and 7 are more relevant to the function of the stations. In terms of esthetic principals, Shahriyar station scores the highest among the stations in the first phase of the first line. Because of its proximity of Elgholi depot, station 1 has easier and greater access to infrastructure facilities while station 5 has the least among the seven stations. Station 3 is in close proximity to commuter taxis and also in good order among other stations. The findings of the article have implications for giving priorities to organizing the subway system in Tabriz.

In recent years, there has been extensive literature on spatial structure of metropolitan areas and its economic consequences, with emphasis on concepts of poly-centricity and agglomeration economies. Defenders of polycentric regions claim that these areas can make a balance between advantages and disadvantages of agglomeration to create competitive advantages comparing with mono-centric regions, while avoiding excessive concentration and congestion of competitor region. However, there are few studies that have examined these approaches adaptively. Hence, this paper aims to make a comparative study of two metropolitan areas of Shiraz and central Mazandaran to investigate some of the claims about links between spatial structure optimization and advantages of accumulation. The Methodology of the research is based on descriptive and statistical analysis such as Ciccone-Hall and Herfindahl index. The results showed that the spatial structure of the region with emphasis on the concept of polycentric and distribution is scattered and polycentric pattern of central region of Mazandaran against centralized and mono-centric Shiraz metropolitan area. In this context, from the perspective of the consumer, the lack of a dominant urban culture and urban environment should be considered as an important factor in the failure to achieve urbanization advantages. This is an obstacle to achieving higher performance services and facilities, especially lowering private sector investment. However, the findings from the analysis defend relatively equal diversification of production in region of Central Mazandaran against Shiraz metropolitan area, and consider it as a big factor to create complementary links between urban centers in the region. Also, it seems a polycentric pattern without sharing their resources in order to provide more facilities and Infrastructures in regional level cannot be defined in achieving localization advantages as a close rival to mono-centric metropolitan area.

To study the synoptic - thermodynamic characteristics of the cloud mechanism in Azerbaijan in 2009-2000 period using the average rainfall of 15 mm and inclusive precipitation, 13 days was chosen indicators. To evaluate the development of the synoptic systems, sea level pressure and high levels of 850 and 500 HP respectively. 850 and 700 hPa specific humidity of the review process of cloud formation and water vapor transmission to the regional case study was used. To review upward movement that causes the formation of convective clouds to grow vertically or thickness, the vertical component of wind velocity in the coordinate system pressure at the level of 500 HP, were used. The stable and unstable atmospheric conditions were analyzed based on the graph skeu-t Tabriz. Synoptic results showed that the samples case study, the formation mechanism of the regional systems that have passed careful, depend on many factors. As a result of the deepening trough in the middle level of the high latitudes near the poles towards the south of the Mediterranean, the Red Sea along the meridian pressure inverted trough extends towards the south of the Mediterranean Sea. The northern part of the trough to trough height of the middle level, a Low pressure systems form when cold air and moisture from the middle latitudes of the Southern latitudes. Warm weather and cold fronts associated with this system is that, by moving his hand from the East Azerbaijan passes are causing precipitation in the region. Thermodynamic results showed that the thickness of the cloud and precipitation intensity and positive relationship is nonlinear. That the amount and intensity of precipitation than the thickness of the cloud, other factors are involved. The results of thermodynamic parameters showed that the convective rise in spring and autumn with warm and cold fronts are causing heavy rainfall in the region.

Electronics City will be affected on various land use via electronic shopping, electronic services, electronic communications, e-learning, e-banking, teleporting and electronic entertainment. Tabriz has not been exempting from this category. In this research, by using descriptive - analytic method and AHP model, first the effect of electronics city on each of urban land uses in the areas of Tabriz has evaluated and the significance of each factor is determined. Then, according to this matter that Electronics City in all land uses led to reduce area and only need to increase the space in residential users, the process of research has follow din two scenarios. In the first scenario, it has assumed that all require to land use in the area; it must be protected in their regions area and in the second scenario, providing additional needs to residential users that arising from electronic city has considered outside the city limits. Finally, in each of the regions, priority allocation of conservation areas to different land use has analyzed. The results indicate that the main priorities of allocating space in ten regions of Tabriz, is related to land sports, culture and green space. According to land use development, there is no ability to provide the demands of citizens based on real spaces and need to use of electronic city services and virtual supply is necessary.

Considering high construction and population density, unstable structures, narrow streets, and high rate of inclusion in cities, it is necessary to plan and carry out researches to minimize vulnerabilities caused by natural events. To accomplish this, one of the important efforts can be identifying effective factors in reducing vulnerabilities of cities against earthquake. Recognizing and investigating the vulnerability of urban areas, particularly within the context of the old fabrics and informal settlements, is of great importance. By specifying vulnerable areas against earthquakes, with an awareness of the damage they may suffer, cities can be planned and designed in a way that the least damage during an earthquake is received. In this paper, by picking several indicators such as land use, street width, number of floors, rate of inclusion, population density, fabric segmentation, occupied space, floor-area ratio of buildings, built quality, structure type, building age, access to open spaces and distance to the main seismic belt and by employing the MIHWP model along with the capabilities of the Arc GIS software and by multiplying and overlaying the data layers of indexed indicators, the seismic vulnerability of the region 10 of Tabriz has been represented. The results conclude that the buildings with low width streets, high number of floors and high value of enclosure, less lot areas, high occupied space and building and population density, low built quality, unstable structures, old buildings, more distance to open space and proximity to major seismic belts, have been rated as high vulnerable areas. Within the region, moving from the North West to the center and North East, vulnerability considerably increases

The rapid urban growth of recent decades in Iran has resulted in extensive changes in urban fringe land-use patterns.It has also had considerable environmental and socio-economic impacts on these areas.Assessing changes of the past land-use patterns and simulation of their future changes are of vital importance inpolicy making and planning processes. Combination of geographic information system (GIS) and remote sensing (RS) may producea suitable tool for gathering and analyzingdata regarding land use changes. This articleuses the CA-Markov model to assess and simulate changes in land use patterns in Miandoab city.In the first stage, by using the multi-temporal satellite imagery for the years 1984, 1997 and 2010, the urban and urban fringe cover/land-use maps was created and changes was evaluated. Results indicate thatin the period of 27 years, urban and urban fringe land area increased to 1013 hectares and farm land-use area decreased to 1114 hectares. Then, by using Markov model, matrix of transition area of land-uses for the period of 1984-2010was calculated. In the next stage, the suitability maps of land-uses by using of mulicriteria evaluation methods were created. Finally, for forecasting the future changes of land-uses until the 2025 year, we used the CA-Markov model. Simulation results, indicatethat thedecline trend in farm lands and the trend increase in urban lands will continue. Therefore, if the current trend of changes continues without a sustainable development policy, it will have to a serious downfall in environmental and socio– economic conditions.

Rapid, irregular and unbalanced growth of the world population during past years, particularly in developing countries, have been caused many problems in the areas of environmental, economic, social and cultural for urban planners. These situations request new methods and tools to model and predict urban future changes. Due to simple and dynamic structure and utilizing spatial characteristics, Cellular Automation (CA) model widely uses in spatial-temporal modeling problems such as urban extension. This paper develops a Fuzzy-CA method to model urban extension. In conventional CA method, state and position of pixels and transition rules are defined certainly. The definitive expression of components of the complex processes needs a large amount of data. However in most cases accurate data are not available. As a result, integration of CA method and fuzzy theory would be useful to model urban extension. In this paper a Fuzzy-CA method is developed and tested in Shiraz city between the years 2004 to 2009. The results of the proposed method show 80% accuracy in comparison to real data have been captured from satellite images. However, an accuracy of 75% has been reported for this case study with utilizing conventional cellular automation.

City councils always played a major role in improve the quality of citizen life. This study which evaluated the performance of Sardasht city Council has been done with descriptive-analytical and according to survey and library data. Proven method assumptions in this study citing on data from the questionnaires have been analyzed. Statistical population includes two groups. First was in urban experts and second was the citizen of the Sardasht city. For determining the sample size for the group of residents Cochran's formula was used. Which sample size was 384 that was completed by random and stratified distributed. But for sample of experts we used snowball method which the number of experts samples in this study reached 15 cases. KS test was used in analyzing the data in order to determine the normal distribution of scores and use one-sample T-test and Binominal test to evaluate the performance of the city Council Sardasht and Also Mann–Whitney U test and independent T to compare the views of citizens group and experts group. The results of this study indicated that economic performance of the city council of Sardasht was not good. Of course the social function was better than economic performance and is investigated beyond acceptable medium. However, the best performing of city council of Sardasht is cultural performance that this value is 3/89.

It merely is an effort to achieve quality standards in the urban board. Meanwhile the issue of quality in special residential areas such as deteriorated textures, due to the their large population and building density and their lack of organic relation with urban structure, has more importance and complicacy in comparison with other residential areas. Accordingly, trying to understand the concept of the quality of environment, indicators and affecting criteria on the amount of quality of these textures are identified. Indicators used in this research by looking at the subjective quality of the urban environment are the product of individual perception and satisfaction of citizens from their environment life. The study area is located in Abkouh in the Mashhad Metropolis region 1 Having the fact, this research is practical and its methodology is based on descriptive and analytical research method. For the measurement of the amount of environmental quality indicators of satisfaction, T test, to determine the significant relationship between individual variables and environmental quality indicators-Chi-square test and to determine the intensity and direction of the correlation between them Kendall Tau and Kramer test were used in the SPSS software. The results of research show that the rate of satisfaction of environmental quality indicators in the study area is on the lower level.

Housing as a heterogeneous product, lasting, immovable and assigning is the main part of family budget. In other words, the housing as one of the main goods not only contains use value in its nature but also is considered as an investment in which selection of the price has main role. Therefore this article attempts to explore the affecting variables on housing prices in the Sahand new town. The research method is correlation test and the use of hedonic function. The results showed that the factors like lot size and building area, number of floors and the number of apartment in per floor among the physical and spatial factors’ distance to nearby park and green space, distance to nearby shopping center have the highest effect on housing price. The correlation analyses used were Spearman and Kendal methods. These analyses only used for spatial factors. Results showed that there was straight correlation between the price and nearby mosques, which means the price arises when it is far away from the mosque.
