Ecological capability assessment is part of the land preparation process by which the capacity of each area is assessed for specific uses and the area's capacity is determined and graded on the basis of scientific components. In this ecological approach, human activities in the territorial area pave the way for each region's capability and potential to achieve sustainable development. The purpose of this study is to evaluate the ecological potential of agricultural land use in West Azarbaijan province. This study is of applied purpose and of descriptive-analytical methodology. To do this research, using effective information layers and GIS software, effective factors in assessing ecological ability were determined, weighted, evaluated and their layers were drawn and finally an ecological power map was prepared. It was mentioned. The results of the analysis indicate the differences in the ecological potential of the provinces. In the field of agricultural ecological potential, the cities of Urmia, Khoy, Naghadeh, Miandoab have the highest potential due to slope, high soil quality, good temperature and rainfall and low soil erodibility. Be it. In contrast, Sardasht and Chaldaran cities have the least potential. Because of Sardasht city due to high slope and mountainous terrain, impassable highlands and valley and non-flat lands, forest vegetation, low air temperature and high number of frost days and Chaldaran city due to high erosion and abundant rangelands, lands Mountainous and lower rainfall have lower agricultural capacity than other cities in the province.impassable highlands and valley and non-flat lands, forest vegetation, low air temperature and high number of frost days and Chaldaran city due to high erosion and abundant rangelands, lands Mountainous and lower rainfall have lower agricultural capacity than other cities in the province.

Viability refers to an urban system in which the social, physical, and mental health and quality of life of all its inhabitants are taken into consideration. On the other hand، the issue of citizen participation in the economic and social development of cities, has been considered in urban development studies and planning since several decades. Therefore, it will be a livable society that cares about the needs of the people of that society, respects their demands, and does not neglect the participation of citizens in the affairs of the city. The purpose of this article is to identify the relationship between social participation as one of the components of social capital and urban livability. To achieve this goal, a descriptive-analytical survey method has been used and to collect information, a researcher-made questionnaire has been applied. To analyze the research data, SPSS، GIS، super decision software has been used. The statistical population includes citizens of the five regions of Zahedan that 383 residents have been selected and studied by cluster sampling with systematic random sampling. The results of ranking the regions in livability indicators show that region 1 as a new region with a proportional distribution of land use and urban services، adequate access to educational and health services، security and urban environment is a relatively desirable region in Zahedan and region 3 with informal and turbulent housing texture is the most undesirable region in terms of social livability. The results of Pearson correlation coefficient test show high correlation between the components of social participation and the dimensions of social viability in the areas of Zahedan; this indicates that the more social participation among the citizens of Zahedan, the better the city is in terms of social viability.

Environmental sustainability assessment represents a set of measures that provide useful information about the effects of the environment on humans and vice versa. Assessing the environmental sustainability of cities is necessary to achieve appropriate urban planning in line with the variables of the natural environment. Considering the role and importance of the environment in the lives of citizens and the existence of environmental problems in Zahedan, the present study aimed to investigate the environmental sustainability of Zahedan city in comparison with its rival cities in the province. The present study was applied and descriptive-analytical in terms of purpose and method. The statistical population of the study was officials, professionals, and related experts in the selected cities of the province. For this purpose, cities with more than 50,000 people (Zabul, Saravan, Iranshahr, Chabahar, and Zahedan) were selected. The Meta-SWOT model was used for data analysis. For many years, the use of the SWOT model has shown that this model, in addition to being based on mental inspirations, lacks predictive power due to avoiding quantification. So, in this study, the Meta-SWOT model was used to eliminate the disadvantages of the SWOT model. The results obtained from environmental sustainability showed that the city of Zahedan had the first rank in the production of waste materials. Also, in terms of macro-environmental factors that need special attention, the development of the use of renewable energy resources and reducing and minimizing the consumption of fossil fuels were the priorities. Factors that rank next included establishing laws for environmental sustainability, increasing funding for environmental clean-up, and optimizing waste management and waste recycling.

IntroductionIt may be asserted that housing problem is globally widespread. However, in developing countries, this problem has become critical because of population and urbanization's rapid growth, internal immigrations, lack of sufficient financial resources, problems regarding land supply, construction materials supply and lack of specialized human forces and, most importantly, lack of proper policy and planning concerning land and housing. As one of the developing countries, Iran is not an exception in this regard.
The analysis of qualitative and quantitative problems of housing is done through items which are seen as variables named "housing indicators" which indicate the different economic, social, cultural, and physical dimensions of the housing as well as the key tool for portraying the perspective of the housing and its planning. The study of physical indicators and form of the housing has special importance. This research tried to study and evaluate the physical indicators of the housing in Piranshahr and analyze the features, characteristics, and generally, the physical condition of the city (based on 15 districts) from different aspects to the extent that the information can be extracted. Generally, the most important goals of this research can be summarized as follows:Correct and sufficient identification of the status quo of Piranshahr in order to achieve a proper and efficient planning for the physical condition of the housing;
Identifying and understanding the physical condition of the neighborhoods in the city by emphasis on its effect on the spatial justice.
Theoretical FrameworkHousing as one of the most important basic necessities of mankind is known to tremendously affect human health and well-being. It is widely acknowledged that adequate housing is essential for good life. Housing is a very complicated and widespread issue with different spatial, architectural, physical, economic, social, financial, psychological, and medical aspects. For this purpose, various definitions have been presented for it such that the housing is considered as a physical place and shelter as well as one of the basic and essential needs of family. The study of the housing indicators is one of the known tools and methods for understanding the nature of governing features on the housing which by its help, we can identify effective procedures in the housing. Based on this, housing indicators are the most important key tools in the housing planning which can be used to identify the effective parameters for housing and facilitate decision-making in the process of the housing planning. Housing indicators are divided into four major groups: 1-social, 2-economic, 3-physical, and 4-demographic.
MethodologyThis research is of applied-developmental type which used the descriptive-analytical method. The statistical population of the neighborhoods was all the statistical and extracted data related to Piranshahr city in 2012. The studied indicators included 5 major categories: the age of buildings (in three levels of less than 10 years, 10 to 30 years, and more than 30 years); the quality of buildings (in four levels of repaired, ruined, renewed, and maintainable); the granularity of the residential units (in 7 levels); the number of the floors (1,2,3 and more than 4 floors); and aggregates (in 5 levels including clay, metal frame, wood-block, brick-block, and iron-brick). For this purpose, in order to weight the indicators, network analysis model was used, and in order to rank the urban neighborhoods and evaluate their condition, fuzzy TOPSIS model was used.
Results & DiscussionThe study of the current condition in Piranshahr city shows that the condition of housing is not equal in different neighborhoods of the city and they have significant differences compared to each other. However, by a look to the condition of housing indicators in different neighborhoods, it becomes clear that a significant percentage of the houses has not been developed in accordance with the available standards. Also, the final indicator of the physical quality of housing in Piranshahr shows that 26.7% of the neighborhoods in the city have desired quality, 40% have moderate quality, and 33.3% have undesired quality indicating the relative difference of the neighborhoods in the city.
Conclusions & SuggestionsRegarding the obtained results, we can claim that most of the neighborhoods are not in suitable conditions in terms of the number of floors indicating the spatial difference in the residence pattern of the urban neighborhoods. Furthermore, the findings showed that most urban neighborhoods are in an instable condition. Finally, it is hoped that the suitable condition is achieved in the urban development plans as soon as possible by the cooperation of authorities and people in the proper implementation of the urban development plan, land preparation, and renovation of the old texture.

Green spaces and parks are one of recreational services and in particular as one of the important uses that deal with large urban populations which include significant levels of city area are facing problems such as shortage, Inappropriate distribution of the population needs and so on. Now the purpose of this study is to analyze the distribution of green spaces and parks in the city of Piranshahr and how to organize appropriately. The research method is Cross-sectional. To analyze and classify information ANP, AHP models and network analysis model is used and to perform this operation ARC/GIS, Super Decisions software are used. The result of the analysis indicates that green space in the city of Piranshahr in terms of compatibility with other users and also in terms of access, is inappropriate. Then with combination of different effective layers, the final map of the optimal areas for construction of urban parks were developed and recommended.

The topic of land and how to use it have always been the main topic of the urban planning and the space-place assessment and organizing of the efficient and urban performances is one of the most important and most effective axis urban Sustainable Development. The aim of the performance of this reseach is the quality and quantity assessment of the urban land use with constant Sustainable Development in Piranshahr. The manner of this research is analytic descriptive. To this purpose، there indicators of capacity compatibility and social justice have been used to achieve the sustainable development. In the first stage، it is paid to the quantitative assessment of existing uses and capacity index analysis، in the second stage it is paid to the qualitative assessment of use in view point of compatibility by using compatibility matrix and analysis of social justice index with the model of the nearest neighbor and swot model. The results of the quality and quantity analysis show that often efficient face with lack. This lack equals with 175. 5 hectar. Also the most extent of Inconsistency is in the Usage Industry، Administrative، Residential and educational. This situation is expressive of the lack of the balance and disharmonious between the efficient that was caused by the urban planners lack enough attention. So it is essential to fit the environmental balance and economic and cultural of the urban Sustainable Development in the planning process.
