Potential physiographic zoning of wheat using weighted linear combination (WLC) in Golestan province
Abstract:   (3913 Views)

To evaluate the agricultural lands in Golestan province for wheat production, geographic information system (GIS) and weighted linear method (WLC) were used. For this purpose, the requirements of the crop and environmental variables were determined and according to current elements output maps were prepared. Environment variables were included slope, aspect, elevation and the soil texture. Data were standardized by fuzzy method, and analytic hierarchy process (AHP) was used for weighting the criteria. Finally, wheat cultivation potential map was prepared by using weighted linear combination (WLC) in the software IDRISI. The results showed that the weighted criteria of AHP, the amount of slope with 0.3572 had the highest coefficient in the ranking, but the elevation 0.1112 had the lowest coefficient based on the output map which obtained from weighted linear combination, the located lands in East, Southeastern and South had the lowest potential production for wheat. These areas were consisted of steep slopes, highest elevation and less favorable area in terms of areas which had unfavorable topography areas and other areas that located in the West, North West and center of the province had the best potential for wheat production due to favorable soil, low slope and elevation.

Keywords: Elevation, Soil texture, Geographic information system, AHP
