Cangyuan County is located in the Yunnan Plateau. Due to the complex and changeable geological environment, frequent tectonic activities, and the influence of precipitation and other inducing factors, this area has become an area with frequent geological disasters, which seriously threatens the safety of human life and property. In order to comprehensively evaluate the risk degree of geological hazards in the study area, eight evaluation factors including elevation, slope, slope aspect, rainfall, fault distance, water system distance, road distance, and engineering rock formation were selected, and 192 geological disaster points in the study area were used as samples to construct a The super-efficiency DEA-information model is used to evaluate the risk of geological disasters in the study area. The evaluation results show that the high and extremely high risk zones of Cangyuan County account for 54.2% of the total area of the study area. There are 166 geological disaster points in the area, accounting for 86.5% of the total number of disaster points. The ratio of disaster point ratio to area ratio With the increase of risk, the AUC value calculated by ROC curve was 0.755. The above data show that the evaluation results of geological hazard risk based on the super-efficiency DEA-information model are more realistic and have high evaluation accuracy, which can meet the needs of geological hazard risk evaluation in the study area.
