Abstract
The correct and optimal use of land requires a detailed evaluation of agricultural ecological resources. Evaluating the potential of land for growing different crops is the first strategic priority to increase production and optimize resource consumption. The purpose of this research is to identify the climatic factors and elements, soil and topography affecting the cultivation of rainfed wheat in a part of the rainfed fields of Hashtroud city in East Azarbaijan province and to delineate the areas prone to the cultivation of this crop using Geographical Information System (GIS) and Analysis Hierarchy Process (AHP) was done. First, the ecological needs of dry wheat were determined and graded using available scientific resources. Then the required thematic maps were prepared and classified. Hierarchical analysis process was used to determine the weight of the criteria. Finally, by combining and overlapping these maps in the GIS environment, the dry wheat zonation map was extracted. The results of zoning showed that wheat is placed in 4 zones (very suitable, relatively suitable, weak and unsuitable) in terms of land suitability. About 28,700 hectares (22%) of the land area of the study area are very suitable, about 33,373 hectares (26%) of the land area of the study area are relatively suitable, about 35,447 hectares (27%) of the land area of the study area Poor study and about 33,299 hectares (25%) of the studied land area were found to be unsuitable for growing dryland wheat crops.
