One of the major issues of population in the world is generally the problem of the aging population and the consequences of it. Therefore, the aim of this study is to evaluate the city of Tabriz based on favorable city indicators of the elderly (such as housing, social participation, respect and social support and health services). The methodology of this research is descriptive-analytical of the applied type and the method of collecting data and documentary and survey data. A questionnaire was used to collect data. The statistical population includes all 60 years old and older elderly people based on the general population census and housing in 1390 in the regions 1 and 10 of Tabriz Municipality. Using the Cochran formula, the sample size for area 1, 138 and for area 10, 138 it is achieved. Then, using the available sampling method, distributed among the regions 1 and 10 of Tabriz Municipality. Statistical analysis and structural equation modeling (SEM) have been used in data analysis. The results of the study indicate that the average housing situation, the rate of social participation, social support and health services among the elderly were moderate to low And the average respect index among the elderly is moderate and the level of each of the desirable city indicators of the elderly, except for the housing index, does not differ significantly in terms of housing type and residence area of respondents. Also, the effect of social support and health services on respect is equal to (0.44), the effectiveness of civic participation on respect is equal to (0.23) and the effectiveness of social participation on respect is equal to (0.17). Regarding the coefficient of explanation, we conclude that three variables (housing, social support and health services and social participation) explain a total of 0.82 of the variance of the variable of respect, and another 18.1% is related to factors other than existing variables.

Metropolises are as population and traffic density centers and their consequences are more than other population centers. Various metropolises present different solutions based on their circumstances and characteristics of transportation. The major issue about transportation in metropolises is weakness of strategic plans in order to apply the plans for intelligent transportation system that impresses urban transportation. Management organization of transportation in metropolis of Tabriz presents some solutions sporadically that are not enough to solve traffic problems. The purpose of this study is to present a model to prioritize development strategies for intelligent transportation system in order to cover strategic plan for transportation management. In other words, this paper is concentrated on combination model of prioritize strategies. The procedure of this research is that after literature review, development strategies of intelligent transportation system which is as a result of logic and scientific management model (ANP،QSPM), is prioritized by using strategic approach. For achieving this goal, combination procedure is done and the relationship of different variables to present the real priority of strategies is considered. Finally, findings of this combination procedure are compared by using Spearman rank order correlation. The result of combination procedure and comparing it with Spearman rank order correlation illustrate that strategy entitled “coordination of all organizations to enhance public infrastructure in order to develop intelligent transportation system” in both analysis (QSPM and ANP) is prioritized as a major strategy and other strategies have different priorities.

Studying the future and planning for its, is an inseparable part of the process of planning. In most cases, studying future, with emphasis on predicting and analyzing methods, has made innumerable problems in conducting different programs. These problems often arise from inattention to political, social, economic, and cultural effects and also an indifference to the novel or developing technologies in human’s life, or they could be because of neglecting the leading forces and key factors affecting the facilitation of the resolution of future problems. The goal of this study is to identify the key factors effective on the House price of Tabriz metropolis. In order to do this, Delphi technique was used for identifying the effective factors on the House price the result of which showed 40 initial effective factors on the House price were identified. In the next step, for extracting the key factors effective on the House price, Cross Impact Analysis method was used by software and the result was to identify 12 key factors effective on the House price Tabriz metropolis from the 40 initial effective factors. The results of the study show that 12 key factors are the main and effective actors in determining the house price of Tabriz metropolis.

Cities as a living environment play a significant role in creating satisfaction, they indeed shape human's lifestyle and determine their life quality. Regarding the quality of man-made environments not only encourages them to cooperate, but also induces a sense of satisfaction among individuals. Urban growth and rapid urban expansion have caused various crises in terms of urban life including environmental challenges and declining the quality of urban environs. Following increased urbanization in our country and rapid changing space for several reasons in terms of urban texture, the quality of urban environs has seriously declined. When it comes to environmental quality, the emphasis is still over construction and physical shape. The paper tends to measure and zone the physical environment quality of the middle texture of Tabriz city based on recent statistics and data. The research method is based on the objectives applying descriptive- analytical in terms of its methodology. During first steps of sample collection, we initially measure the quality of urban environment through field studies preparing and filling out some questionnaires. And in the second step, we apply softwares including: EXCEL, CHOICE, EXPERT to measure the data and finally apply ARC GIS to display the research findings. However the yields of central tissue zoning of Tabriz reflect that 5.77% of regional area is in an unfavorable condition, 19.38% favorable condition and 74.83% is in moderate utility status.

Tourism today is one of the most important and effective economic issues and of the important factors of Outstanding communication, social and cultural in the worldwide is considered. In fact, the expansion of the economic, health, security and communication infrastructure in the twenty-first century has made tourism an inevitable reality in human life (Saghaei and Alizadeh, 2013: 2). Hence, tourism is one of the key industries in any society that can attract planners attention, Because it affects many sectors of society, including the economic, cultural and environmental sectors. On the other, The large volume of travel in recent years has made tourism one of the largest industries in the world (Kazemi et al, 2012: 48), So that the income of tourism and tourist With transportation of passengers in about 17 percent of total world exports make up. Given the growing importance of tourism in today's world and the competitiveness of the tourism market around the world, Tourist destinations are increasingly competing with each other to attract tourists. The expansion of the tourism industry in every part of the world requires special conditions and conditions such as climate, ancient artifacts, natural attractions, traditions, infrastructure, facilities and equipment (Pourahmad et al, 2013: 2). So each of the tourist destinations should try to increase their share of the industry and its revenues. On the other hand, On the other hand, Should be noted in today's competitive world, The first trip to a tourist destination It does not mean the success of tourism destination, It is also a repetition of the trip to the tourist destinations and the introduction and promotion of it for potential tourists, which can serve the purpose of tourism in the long run. Hence, loyalty to the destination of tourism and its influential factors play a significant role in their long-term success. Therefore, efforts should be Loyalty to the destination of tourism and the factors that create this loyalty are identified and strengthened. Given the importance of brand loyalty to tourism destinations, The present study aims to investigate the factors affecting the loyalty of tourists to the tourism destination of Tabriz. Emission reduction of carbon dioxide and its impact on global warming process is one of the most important results in the use of renewable energy sources. In urban areas, solar systems stationed on building roofs are the most appropriate utilization method of stable source of solar energy. Urban compactness is a major urban form parameter that affects the accessibility of solar renewable energy in the built environment, so it is essential that the effects of urban compactness on buildings utilization of solar energy, be surveyed. The aim of this study is the evaluation of solar energy potential in urban areas and determination of the relation between urban compactness indicators and solar energy potential in the local scale. In this study, the annual solar radiation modeling for each of the building surfaces of the study area, over one year period, was performed using the Solar Analyst model. On the other hand, the relation between various compactness indicators including site coverage, plot ratio, volume-area ratio, Entropy, population density and building density with Annual solar radiation received by the study area was explored and using least squares regression model, the relationship between the solar radiation and urban compactness indicators was determined. Also potential of using two types of active solar systems including Building Integrated Photovoltaic Systems (PV) and Solar Thermal Collectors (STC) was evaluated. According to the results, the annual solar irradiation increase from 507 (in compression areas) to 741 (in scattered areas) Kilowatt hours per square meter. Volume-area ratio shows the highest determination coefficient, R2 equal to 0/805 with annual solar radiation. Also in the study area, the building roofs potential for the development of PV systems much more than STC systems, influenced by the degree of urban compactness.

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

Abstract In this research, by using 10 natural criteria and AHP model, Tabriz district was studied from natural environment perspective to identify the optimal location for construction of Maskan- Mehr and compare the current Mehr housing location. The method of this study is descriptive-analytical and the data were collected by documentary and field study methods. According to the proper zones identified for localization of Mehr housing in Tabriz district and since all zones were not optimal and lacked capability of planning, so by using TOPSIS, SAW and MORIS, the optimal zones were prioritized from implementation perspective. Also, the analysis of sensitivity of the identified zones was investigated based on 10 localization criteria. The results show that there are seven proper zones 10 km of Tabriz that have the best conditions for localization of the Mehr housing according to studied criteria. Also, ranking models show that the first zone is near to Tabriz- Maragheh road. The results show that Mehr housing in Tabriz that selected based on the economic conditions and land ownership issue could be localized in a proper environmental conditions near to Tabriz to consider environmental and natural disasters in addition to economic support of the owners of these dwellings.

Increment of soil carbon is an appropriate method for reducing atmosphere dioxide carbon density resulted from foresting in the unutilized and destroyed lands and its optimal management due to increase of concern about universal heating and changing of climate. According to universal heating and expansion of urban industries issue in the air pollution; capacity of Tabriz Province lands in establishing of parks has been investigated by employing AHP. The data were collected by available basic maps and spot 2005 satellite images and also field studies. The zone digits of maps were converted to criterion maps (slope, direction, height, land usage, geology, soil, city, communication network, village and rivers) by using spatial information techniques and they were valuated for paired comparison. The value of each scale was considered according to capacity of each unit. The paired comparison of the spatial information techniques criteriawas conducted by using Marionian attached program in GIS and the studied criterion weight were calculated. Then the final map in raster format was extracted by using each weight and was categorized in five classes range from very weak to very good and the best location was extracted with an area about four percent of the whole Province

The aim of this study is trend analysis of meteorological parameter including mean wind speed, min, max and mean air temperature, difference between the min and max temperature, pan evaporation, average relative humidity, sunshine hours, total precipitation, the number of days with precipitation more than 1, 5 and 10 mm, the number of days with dust, number of the days with snow and the number of days with visibility less than 2Km, degree days based on 18 and 21 oC at Tabriz station during 1970-2005 in three time scales, monthly, seasonal and annually using the non-parametric Mann-Kendall (MK) method. Trend analysis was conducted using two methods, which are conventional MK (for series having insignificant autocorrelation coefficients) and modified MK (for other series) in three significant levels, 1%, 5% and 10%. Trend slopes were calculated using Sen’s estimator. Results showed that in annual time scale, pan evaporation, min, max and mean temperature and degree days based on 18 and 210C have significant increasing trends at 5% level but precipitation, number of the days with precipitation more than 1 and 5 mm and degree days based on 180C have decreasing trend (at 5% level). Other parameters did not show significant trend in annual time scale. Trend slope of annual precipitation was -2.28 mm/year and trend slopes of all three elements, average, max and min temperature were 0.06 0C/year. Observed trends in studying parameters indicate climate change in Tabriz.

Trend analysis of 27 indices related with extreme temperature and precipitation during 1961-2011 were conducted in Tabriz using the non-parametric Mann-Kendall test and Sen’s Estimator Slope methods. Furthermore Generalized Extreme Value distribution fitted to observational extreme events. Values of quantiles of the variables were estimated for different return periods. Results indicated that during the past half century, trends of indices for summer days, tropical nights and warm nights were upward and statistically significant. Trends of indices related to ice days and cool days were downward and significant. Minimum values of daily minimum and maximum temperature in year indicate significant increasing trends. Indices of number of days with precipitation greater or equal to 10 and 15 mm, consecutive wet days, total precipitation in wet days and total precipitation when rainfall is greater than 95 and 99 percentiles have experienced significant decreasing trends. After fitting GEV distribution to annual values of daily minimum and maximum temperature as well as daily maximum precipitation in Tabriz Growth curves and Q-Q plats were illustrated. Investigation of plots indicated that this distribution function has more capability in fitting of time series of extreme value even in tails of the distribution.

In this research we have studied Tabriz temperature inversion using radio-sound information, Skew-t maps and synoptic maps during the 2004-2008 period in daily and monthly scales. After reviewing the information and data at first days with weak, medium, and intense and very intense temperature inversion conditions were specified. Thereafter, the synoptic pattern of very intense and weak samples relating to three earlier days and two days after the peak of temperature inversion were analyzed using ground surface synoptic maps of 850 and 700 hp. The results indicate that there is a strong correlation between the occurrence of high pressure systems and the intense and very intense temperature inversion. In such a way that the intensity of temperature inversion has a straight relationship with synoptic pattern conditions especially the entrance of high pressure systems in the area. When the high pressure system in a stable condition is coming to the area in few-days scale, the intensity of temperature inversion is maximized. After the entrance of the low pressure cells, the temperature inversion is eliminated. Findings of this research have shown that with analyzing the synoptic systems that lead to the occurrence of temperature inversion and through the recognition of the patterns dominating over it, one can predict extreme temperature inversion. In addition, we can distinguish the patterns leading to the air pollution

In historical-cultural tourism discussions, vicinity applications of historical places are important in terms of the interaction of tourist with the place. In most cases the surrounding applications of historical places have less compatibility with historical spaces and result in conversion of the valuable historical places to the separated places and free from the spaces connected to them especially in terms of spatial function. This paper is based on evaluating the compatibility rate of the surrounding applications of historical works in cultural-historical area of Tabriz with the aim of attracting tourists. In order to do this the needed data have been collected from tourists by using questionnaire, and the statistical calculations are made to find the relationships between the variable using SPSS software and chi-square tests. The results show that changing the application patterns of surrounding spaces of historical works would increase the residence period of tourists and visitors of historical places.
Therefore there should be an effective planning to provide supportive and service spaces surrounding the historical places. On the other hand considering the tourism paths and designing the connecting rings in the distance between historical spaces, along with special facilities, can create a strong incitement for generating new spaces in historical textures and make them desirable and lively places.

Ever growth of population and following of that, increasing of landfills have caused that environmental experts pay attention to it. Understanding of environmental processes require the knowing of ecological relations between life and non-life creatures and nutrient cycle and important cycles such as water cycle and nitrogen cycle. Latexes in produced landfills sometimes persist with heavy metals in many years. Usually heavy metals containing with organic compounds in molecular structure show no severance. Landfill excretion management in suburban areas of large cities such as Tabriz is inevitable. To observe multiplicity layers in landfill excretion we used geographic information system for site selection. Results showed that landfill excretion in Tabriz is none desirable due to the status of groundwater and geological formations and the sense that compost industry to be established in this city.

The thunderstorms are climate destroyer phenomena every year entering irreversible losses on the establishments, farms, houses and so on such as the hail, the flooding rains and the thunder strike. The recognition of the role of these storms is very important that can decrease the possible losses. In the present research after the analyzing the thermodynamic and synoptic characteristics about the Tabriz thunderstorms in a statistical ten-year period (1996-2005) and ensuring the results of the instability indicators, the researches show strong anticyclone dominance on Russia which extends to the westernorth of Iran and causes increasing thermal gradiant at this area. Also in the higher levels, the presence of strong cyclones on the eastern south of the black sea due to the constant raining of the northern latitudes on this area has caused high depth of the entering path of the black sea on the north western of Iran. With the insertion of two low pressure cells of Sudan and Mediterranean on Kuwait and south of Iraq and with the extention of it's dominance toward the western north of Iran and also the presence of a low pressure cell on Hormoz strait and north of Arabia and finally the transfering of heat and the moisture of Oman sea and the Persian Gulf on the areas have provided the necessary conditions for the higher instability and the thunderstrikes.

The meteorological data indicate that secondary climatic features like hails, heavy showers, floods, and lightening are dominant climatic features in Tabriz during the thunderstorm occurrence. The above-mentioned climatic hazards are part of Tabriz climate characteristics and North West region. These hazards bring about a great deal of economic, social, and environmental damages, particularly for formers and animals farms.
The upper level atmospheric data available in the NationalCenter for Environmental Prediction (NCEP) have been used in this article for synoptic study of thunder rainstorm days of 24 and 25 April 2010 in Tabriz. The atmospheric conditions have been analyzed by calculations and the application of drawing methods for the thunder rainstorm occurrence period.
The results of the synoptic analysis showed that eddy and blocking have occurred at 500, 600 and 700 HP levels, along with severe convective instability at all levels of 1000 to 500 HP. Whereas positive and cyclonic vorticity in the atmospheric levels of 500, 600, 700 and 850 HP were affective factors in occurrence of thunder rainstorms during the days of 24 and 25 April 2010. Moisture advection maps showed that the moisture supply source of thunder rainstorms are on 1000 HP levels, while 925 and 850 HP levels of the Caspian Sea and on 700, 600 and 500 HP levels of the Mediterranean and Black seas have occurred during the days 24 and 25 April 2010 in Tabriz and North West of Iran.

During the few recent decades one of important subjects that connected studies of tourism and has been in the center of researcher’s attention, and an image of tourist from a tourism destination. Most results of these researches indicated that mental image of tourists from a destination influences decision making to travel, their behavior during trip and intended renewed trips to that destination. Despite importance of this concept in development of tourism industry, with the exception of a few cases (e.g, in the case of foreign tourists), destination image subject has not been explored in Iran. The main purpose of this research is the examination and analysis of image of interior tourists before and after travel to Tabriz. Methodology of this research is surveying. Required information was gathered using questionnaires and then analyzed with statistical methods by SPSS software. The findings of this study show that travel to Tabriz city has had positive effect on tourist’s image from this city. There has been also positive correlation between tourists image after travel to Tabriz and their tendency to renewed travel to this city. The important point relative to sources is that tourists obtain information of travel by traditional methods (through friends and family members) before traveling to this city.

Since the process of increasing urbanization and its effects, has been made more important the necessity of planned about urban development. Some of the problems about this that we face are: metropolises issues, decreasing the quality of life due to more density of population and activities, new towns strategy buildings - especially in the middle of latest centaury - Thus, this model has been used in many countries (in past decades) and also it has been started since 1357 with the aim of housing for industry workers, and after the Islamic Revolution, mainly to absorb the metropolis crowd overflow.
Now, after more than one-fourth century and beginning of attracting population process for some of new towns, the main purpose of the article is the answer to this question, that "how much this policy was successful?". And we compare the performance of Sahand new town about the absorption of Tabriz metropolis crowd overflow with prior goals that are based on documental and survey methods on sample include 350 household, production and servicing units.
Findings show that, Sahand new town was clearly retarded of contingency planning about buildings, especially population absorption and employment. But the predicted performances to attract the overflow crowd of Tabriz and provide house, some deal orientation resolved to realize the goals.
