Implementation of Agricultural Ecological Capability Model Using Integrated Approach of PROMETHEE II and Fuzzy-AHP in GIS Environment (Case Study: Marvdasht county)

Authors

Abstract

Necessity of consideration future and delineating the characteristics of future development, leads trends to the fields of planning, rational utilization of resources and potential of areas. Assessment of ecological capability, as the core of environmental studies at the prevention of possible crisis, provides an appropriate context for environmental planning. The ability of GIS in managing and delivering new outputs as an efficient instrument in environmental planning is discussed. Therefore, in this study, regarding to some factors such as vegetation type, elevation, slope, texture of soil, climate, vegetation density, Soil drainage, and erosion, we have tried to determine the agricultural ecological capability of Marvdasht County using Fuzzy-AHP and PROMETHEE II, in an integrated–innovative approach, with GIS. PROMETHEE II was used to determine the complete ranking of the alternatives, while Fuzzy-AHP was employed to weighting of criteria. The results showed that the study area contains seven classes of Iran's agricultural and rangeland model. Also the results of sensitivity analysis indicated acceptable effectiveness of the proposed method in ecological capability assessment. The proposed technique can be as a main step in using PROMETHEE II in other raster-based site selection projects in the GIS environment.
