Landslide is one of the natural disasters which cause a lot of annual damage directly or indirectly in the world. Land use changes and high rainfall are leading causes of creation this phenomenon in Beheshtabad basin. Therefore the effective factors were analyzed in this process. The main aim of this study is comparison of two methods AHP and FAHP that are used in landslide hazard zonation by considering the effective qualities and quantities parameters in this phenomenon. First of all, hazard zonation map was prepared with AHP method using inconsistency rate 7%. Then, fuzzy membership function defined for each parameter, and hazard zonation map was prepared to the base of FAHP method. Finally, two maps were compared by Quality sum method and results show that FAHP method has higher accuracy than AHP but different is not significant. In addition, 57.7% of landslide have been located in moderate elevation with 680-760 mm rainfall in Beheshtabad watershed.
