Abstract

Due to the Severe Decrease in resources and land degradation and Increasing population growth, need to Exact planning is the use of resources and land. Modeling the ecological potential of land uses for proportionate utilization of resources provides proper conditions to preserve these resources for future generations. This study illustrates the application of the FUZZY AHP method and fuzzy membership functions in agricultural land evaluation. Based on Iranian literal Ecological Model, soil characteristic data, soil shape and biohydroclimatology were selected as the main criteria. Then, in the form of a model, MCDM and FUZZY AHP Chang method was applied to the substrate weighting process. Then, simple weighting method (SAW) was used to integrate the layers in ArcGIS environment and evaluation was performed. The results showed that there are six classes of agricultural land in the study area and the northern part of the city has high power. Finally, the final map indicated that the total area of the polygons of areas with high to medium agricultural potential is 347 square kilometers. So the FUZZY AHP method, by combining different approaches, can greatly assist evaluators in group decision making.
