Zoning and Measuring Sustainability of Urban Environment Emphasizing Sustainable Development in Yazd Province

Checking development status and constraints of geographic environment is one of the most important issues in two districts of city and sustainable development due to stability and sustaiable development in cities. Indexes of sustainable development in dimensions of environmental geography can be used as suitable criteria to determine the place of cities and solve their problems and shortcomings in order to achieve economic welfare and resident's social-cultural health to obtain urban sustainable development. In this regard having developmental-applied nature and descriptive-analytic method, recognizing and assessing environmental sustainability purpose, that is prioritizing sustainable development in Yazd province and using Entropy-TOPSIS model and GIS, Visio, Grafer, SPSS and Excel software and 50 indicators (hygienic, environmental, cultural, economic and social) the current research aims to analyze the studied subject in the province. The results showed that in matrix model the grouping class difference of province's cities was not regular in terms of population and there was not urban place in intervals between the first floor and top floor of the matrix. So 44.22% of the citie's population distributed on the first floor and the entropy coefficient confirmed it. Its coefficient was (-0.37) in 2006 and (-0.23) in 2011 which indicated the relative movement of the urban hierarchy towards instability and more concentration. Finally development prioritization obtained using TOPSIS indicated that Yazd and Abarkuh were the most developed regions having levels 0.973 and 0.610.
