The implementation of agriculture ecological model using AHP and FAHP models in the GIS environment (Case study: Khaeiz region of Behbahan)

The world today is facing with the crisis of resource destruction. The Optimal utilization of natural resources and regulation of land use based on their ecological potential has important role in environmental management and prevent their destruction in order to sustainable development. Assessment of ecological potential as the core of environmental studies provides a good platform for environmental planning. In this field، geographic information system with high capacity in the management of new outcomes is proposed as an effective tool in environmental planning. In this research، using the criteria of soil، climate، percent slope، type of vegetation cover and water source، agricultural ecological potential of khaeiz region was assessed by using multi criteria decision methods in GIS environment. For this purpose، methods of AHP، FUZZY AHP_Buckley and Fuzzy membership functions were used for standardization and determination the weights of criteria. The results showed that in AHP method، only 3% of the area of a region is suitable for agricultural use which is more consistent with the reality while in method of AHP، 10% of the area of a region has been favorable. Therefore، can conclude that FUZZY AHP method has higher capacity in determining of suitable areas for agricultural use.
