Analysis of Urban Space Sustainability Indicators in Tehran Metropolitan Area with Spatial Justice Approach

The disruption of the distribution system of facilities and services in urban spaces has created the social inequality of citizens in accessing these services. Analyzing inequalities at the level of urban areas is a good starting point for understanding the unbalanced status of cities. The purpose of this study was to analyze and measure the spatial stability of environmental quality in 22 metropolitan areas of Tehran. The purpose of this study is applied and in terms of descriptive-analytical method and method of data collection is documentary. Quantitative models and VIKOR decision making, correlation coefficient, Shannon entropy and Arc Gis geographic information system were also used. The findings show that spatial sustainability indices of environmental quality are not evenly distributed and there is a significant difference between Tehran metropolitan areas in terms of sustainability indices. The results of the model show that the 21st and 18th districts of Tehran metropolitan area with environmental sustainability coefficient (0.188) and (0.177) were ranked first and second respectively. Tehran metropolitan area 10 with coefficient (0.627) ranks 20, Tehran metropolitan area 8 with coefficient (0.650) is ranked 21st and finally Tehran 13th district with environmental sustainability coefficient (0.664) is ranked 22nd. has taken. According to the results of this study, managers and planners of Tehran metropolis can reduce spatial inequalities and environmental instability by changing spatial budgeting policy and reforming and thus make the urban environment more sustainable for different citizens.
