In this paper, a map zonation of landslide hazard and mass movements risks at the Goloord area (north of Iran), using Analysis Hierarchical Process (AHP) was performed based on the parameters of slope, slope direction, elevation, rivers, precipitation, faults, roads, geological unit and land usages. For optimization of the various parameters? effect that would lead to landslide occurrence, the effect dimensions of each of these layers were applied and the zonation of landslide risk in the region was mapped. The AHP operations were attributed with effect numbers between 1 and 9 in accordance with their weight. Then by pairwise comparison of the parameters, the slope of effect of these functions was determined. According to the fault and lithology parameters the most effective layer and human functions including road and land usage are of second priority, topography functions including slope direction, and height are of third level of significance whilst the hydrology function is ranked fourth and thus being in consistency with the land reality. The results illustrated that the Analysis Hierarchical Process (AHP) was appropriate for landslide zonation in this dense vegetation and with the natural geography of the area is consistent.
