Investigation of Landslide Ranger Zoning using Analytical Hierarchy Process in GIS Environment (Case Study: Azadshahr Kohmian Forestry Design)

Landslide is one of the destructive phenomena of natural resources and threatens the sustainability of forest roads. The purpose of this study is to determine the zoning of land risk for the stability of forest roads using the process of analyzing the hierarchy in the GIS. The final zoning map of landslide hazard based on the combination of different maps and main criteria of topography, vegetation, geology, soil, waterways and roads, in 5 classes of landslide danger (40.19%), high risk (30.99%), medium risk (22.5%), low risk (6.29%) and very low risk (0.03%). According to the results, the maximum area of ​​landslide in terms of slope (15-30%), in terms of direction (north direction), in terms of soil depth (100-110 cm depth), soil permeability (with good permeability), in terms of The geology (jmz and ql formations), in terms of distance from the fault (0-200 m), is recorded in terms of distance from the road (0-100 m) in terms of distance from the road (0-100 m). Which is based on the AHP process of accuracy.
