[Abstract]:The geological hazards include collapse, landslide, debris flow and ground collapse. The risk assessment of geological hazards in county units in China is realized by using the method of qualitative and comprehensive assessment by using the sub-measures of geological hazard risk and vulnerability of disaster bearing bodies. The vulnerability of disaster bearing bodies is divided into population safety vulnerability and asset vulnerability, which is characterized by the ratio of population to death due to disaster and direct economic loss due to disaster. Based on the idea of using historical data analysis to guide future prediction and taking the data of geological disasters from 2001 to 2015 as samples, the classification criteria of population safety vulnerability and asset vulnerability are put forward. Geological hazard risk assessment was carried out on 2869 county units in China. The results show that there are 216 geological hazard high risk units (643) and 2010 low risk units (LRUs). The high risk areas of geological hazards are mainly distributed in the Wumengshan area, the mountainous area around Sichuan Basin, and the western Yunnan and southeast Tibet.
