Abstract: 

Zoning of landslide hazards is one of the ways used to determine critical areas. Landslide zoning maps can also be utilized in environmental planning to reduce damage. In the present article, the AHP has been applied to the Gollojeh basin located in Zanjan province. The most important factors in landslide occurrence in this study basin were identified as: Geology formation, slope, land use, height and distance from river, slope aspect, rainfall and faults. After layering and assigning them weights the final map was produced in Arc/GIS. The final results from this study show that the weight of nine criteria are respectively: 0.4092, 0.2485, 0.1439, 0.0786, 0.0479, 0.0309, 0.023, 0.0181 with geology and faults having the greatest and weights to be the least. Finally the landslide map denoting in four domains at very high risk, high risk, medium risk and low risk was prepaerd.
