In order to comprehensively evaluation the susceptibility of geological hazards, Xuanhan County was selected as the research area, and seven factors closely related to geological hazards, such as slope, engineering geological petrofabric and slope structure, were selected to build an evaluation index system. Through the information model combined with analytic hierarchy process, using the spatial analysis and grid computing functions of ArcGIS, supplemented by a certain mathematical model, the geological hazard susceptibility of the study area is divided into three levels, such as high susceptibility zone, medium susceptibility zone and low susceptibility zone. Among them, the high susceptibility zones are relatively scattered, with an area of 372.98 km2, accounting for 8.71%,and the area and proportion of medium and low susceptibility zones are 2 278.18 km2, 1 629.48 km2, 53.22% and 8.71% respectively. Through the verification with the field survey, it is believed that the evaluation results of the geological hazards susceptibility are relatively reasonable, which can provide theoretical guidance and technical support for the prevention and control of geological hazards and land space planning in the study area.
