Geomorphological zoning city land suitability KhomeynUsing fuzzy logicmodeland GIS

Today, many cities of our country, given the unlimited expansion without a program, thus encroaching upon the natural environment and destroy them. Khomeini also the city is no exception. This city, the southernmost city in the Central Province and covers an area of 2267 square kilometers. Doubling of Khomeini city in a period of 15 (1390-1375) annually required detailed planning for the future physical development of the city in the city, are required. The main objective of the present study, the proportion of the city zoning Khomeini geomorphological parameters using fuzzy logic model was And To achieve this goal, effective 10 index vector and raster maps were prepared And for each raster layers, based on field studies and expert opinion, a defined function, but vector layers by being in a range of 0 and 1 other did not need to define the function. After applying function, multiplication, addition and different amounts of gamma phase were also run on the layers. For this purpose, ARC GIS 9.3 and ERDAS 9.1 software was used. Finally, it became clear gamma phase 0/4 city status quo is the best match to suitable land for future development of Khomeini city and a core city in East seems appropriate. Finally, the final maps were classified into 5 classes. As regions respectively; Appropriateness very low 1717.3, low fit with 167.48, with 108.54 average appropriateness, suitability and proportionality too high 76 with 85.12 square kilometers, were identified.
