Abstract Huining County is located in the central part of Gansu Province, and the geological disasters are extremely developed in this area. There are 16 collapses, 12 landslides and 7 mudslides, which have caused great economic loss. In order to divide and evaluate the susceptibility zoning of geological disasters in Huining County, the authors established the geological disaster database based on the regional geological disaster investigations. The evaluation model of geological disaster susceptibility analysis was established by the analytic hierarchy process and statistical method of GIS spatial analysis, and 14 basic indicator layers were selected. The evaluation units were overlaid, analyzed and verified, and the results show that the geological disaster susceptibility in Huining County can be divided into three zones of high easy-happening area, medium easy-happening area and low easy-happening area. It is considered that the evaluation results are in good agreement with the actual situation of geological disasters, with the expert evaluation method to examine the geological disaster susceptibility results. The evaluation results can provide some reference for the comprehensive prevention and treatment of geological disasters in Huining County.
