Rapeseed is one of the most important oilseeds In the world and Iran. Considering the strategic importance of rapeseed, especially in Sistan and Baluchestan province, determining the appropriate areas according to the environmental needs, optimal production and reducing the negative effects of water resources management and conservation of natural resources is needed. Also, due to different fluctuations in production of canola in different years, identification of susceptible and non-susceptible areas based on the recognition of their environmental advantages and restrictions can greatly help the stability of the production in the province. In this research, using the GIS, the required information layers including optimal temperature, minimum temperature, maximum temperature, precipitation, slope, altitude, organic matter, soil salinity, soil texture, pH and nutrient content as nitrogen, phosphorus, potassium, calcium, iron, and zinc in an ArcMap environment were produced. After preparing these layers, the classifying and ranking each layer was carried out based on a simple constraint and the environmental requirements table of rapeseed in four reasonable (very prestigious) moderate, inappropriate (non-susceptible) categories. In this study, the aim of using the spatial analysis functions along with the hierarchical process (AHP) was to identify suitable areas for rapeseed cultivation in the north and center of the province. The results of this study showed that the suitable zone is located more in mountainous and Overlooking the plains of Nimroz and Zahedan.
