Spatial Modeling of Optimal Cropping Pattern by using Analytic Hierarchy Process (AHP) and Geographical Information System (GIS) (Case Study: Plain of Asadabad - Hamadan)

Agriculture as a supplier of food needs of the country is one of the most important economic sectors. The development of the agricultural sector is one of the most important ways of economic development. To achieve this objective, scientific planning is essential for optimum use of available resources and potentials. The purpose of this research is to achieve optimal crop pattern in the plain of Asadabad in Hamadan With effective criteria analysis in the areas of soil and climate. For this purpose, preliminary data were taken from the Ministry of Agriculture, Ministry of Energy and Meteorological Agency. Therefore criteria such as PH, EC, depth and… of soil area and the average temperature of crop growth period of climate area was considered. Then these data layers were created in GIS software. For modeling, to each of the layers using the AHP model, was assigned an appropriate weight. Finally, using the results from a combination of layers optimal areas for crops was introduced And the regions Were classified into four groups: non-susceptible to susceptible.
