On the basis of comprehensively analyzing the impact factors of landslides in Zhongxian，seven factors are selected as evaluation indices including surface slope, surface elevation, terrain undulation, the distance to roads, the distance to rivers, flow cumulant of rivers and annual average rainfall.Every indicator is given a value by using the method of expert system; weight of the seven indices are determined by Analytic Hierarchy Process(AHP); a thematic map for every evaluation index is built by GIS.Based on comprehensive index analysis, the index model of the landslide hazard evaluation of Zhongxian is established.Landslide hazards are divided into 4 rating area, ie.micro hazard, low hazard, medium hazard and high hazard according to the zoning evaluation by comprehensive index.The results show that the 4 rating area respectively cover 689.18 km2、643.91 km2、366.13 km2、334.54 km2 respectivel，and each account for 34.39%、32.14%、17.02%、16.45% of the total area.The results also corresponds with the actual situation of landslides in Zhongxian, which can be used to guide the work of landslide prevention and reduction in Zhongxian.
