Abstract :
Natural hazards such as Landslide is as the nature disasters that have many financial and human losses every year. Today advances in science and technology, provided appropriate fields for the study and reduce these natural hazards. In this respect, the geographic information along with decision support tool used to assess the risk of landslides. The aim of this study was to investigate the effects of different factors in the creation and landslide hazard zonation of landslides in Central part of the Semirom city. For this purpose affecting factors were binary compared using analytical method by indicating the weight of each factor as indicator for their effects in occurrence of landslide. Accordingly, the landslide regionalization hazard map was prepared to the use of weighed information layer and weighted coefficient of each factor. Results of this study show that the analytical hierarchy method is precise method for evaluation of landslide potential due to the use of binary comparison affecting factors and considering numerous factors for landslide evaluation at the same time in comparison to the other prevalent method. The results indicates that the percentage of high and very high hazard class is 40.98 percent in AHP method. As well as material and slope were identified as the most important factors in landslide occurrence in the region.
