Abstract: This paper reports landslide hazard and risk assessment of the Longxi river basin in Zhejiang Province based on GIS and AHP methods. Seven evaluation factors, including slope, aspect, lithology, structure, rainfall, human engineering activities and density of landslides, were extracted from the survey data to calculate landslide hazard assessment index of each evaluation unit. Landslide risk assessment of the Longxi river basin was undertaken using landslide hazard assessment results, population and property vulnerability. The results show that the high hazard zones of landslides are mainly located in Zhangkeng village and Wuyuan village of Daxue Town, and the densities of vulnerable population and property are related to local topography. In flat areas, where population and material wealth are relatively concentrated, occurrences of vulnerable population and property are also high. High risk zones and extremely high risk zones are mainly distributed in Shanmen village, Dianjikeng village, Baimentai village and Dongbei village. The assessment results of landslide risks vary greatly with the densities of vulnerable population and property but similar to zoning of landslide hazards, suggesting that landslide risk assessment is more suitable for the management needs of disaster prevention and mitigation through the combination of the characteristics of natural and human attributes. The field survey has proved that the assessment results of landslides risks accord basically with the actual situation of landslide disaster in the Longxi river basin, and can provide reference for construction and planning of the city and readjusting of population distribution in this area.
