Abstract :
The emergence and establishment of cities is subjected to environmental and natural phenomena more than any other factor. The reason is that natural phenomena have certain effect on location finding, dispersion, penetration and prevalence area, physical development and urban morphology. Following economic and social evolution in the last decades, the trend of urbanization in Iran has led to ungovernable development of cities. This development, improper and incongruence with capacities and natural facilities, has created unsightly consequences in bio-skeletal space of cities. Considering the points mentioned, the purpose of this study is to examine geomorphological limitations for physical development of Kermanshah and its proper location in future development .To achieve this purpose of a topographic map, geology , landslide, land use, erosion, meteorological data, and field research using library resources is taken. Using DEM 1:25000 from Iran Mapping Organization, the information related to slope, the aspect and altitude height of the area have been obtained, then based on fuzzy GIS ARC, the earth has been zoned for physical development of Kermanshah based on two factors including natural factors (altitude height, slope, aspect, geology, fault, flood, landslide, land use, erosion and quadruplet protecting areas) and human factors (highway, power transmission lines, army areas) .The final result of fuzzy multiplying of final map has been obtained from the location tree. Improper area which is 51617 hectare, average area which is 1372 hectare and proper area which is 1126 hectare were recognized. The major proper area is located in areas higher than Ghareh So River which ends up to Kermanshah- Sanandaj road in western part and it continues linear to the eastern part. Another area has been located in south western in Javanrood- Kermanshah road and a polygon has been located in south part of Kermanshah near Islam Abad road. The major part of improper area has been found to be located in north, south and south eastern and in the central part, on Ghare So River due to flooding and fault.
