Abstract :

The reciprocal effect of sustainable and unsustainable ecological resources is considered in the course of assessment of ecological capacity. These resources have reciprocal effects to each other and environment as specifications of each micro ecosystem. So, it is obligatory to utilize nature as it less harms environment and at the same time it benefits human more. Therefore, the main objective of this research, to assess the ecological capacity for surface expansion of town based on principles of reclamation of land, Baharestan new town in Esfahan Province was studied through geographical information system (GIS). At first, the basic studies were done and the theme maps of the area were prepared and then numerated. Digital Elevation Model (DEM) was produced in Arc gis 10.2 using topographic map. Then, the ecological resources Urban development map were produced by overlying the maps of elevation, slope, aspect, soil types, soil texture, soil depth, vegetation cover, geology, landuse, climate and distance to fault with ANP and Fuzzy logic methods in Arcgis 10.2. According to the obtained results, the total development zone with an area of 3264/068 hectares located in the south-east and north baharstan which make these areas and the lack of consideration in connection with the provision of suitable land areas that do not improve performance, 2800/717 hectare area around the planned future development of the city is considered
