Abstract: The assessment of geological hazard risk at county unit is an important part of the monitoring and early warningof the carrying capacity of resources and environment at the macro scale. Such assessment could be as the basis for ecological civilization construction of administrative, and also benefit for the compilation of territorial space planning. In order to overcome the difficulty in quantitative evaluation of vulnerability of the hazard-bearing body, this paper attempts to improve the evaluation method in the author's previous paper. The population and GDP assets in the geological disaster prone area are taken as the statistics of the disaster bearing body of the threatened object, and the correction is made according to the geological disaster survey data of provincial units. Taking the ratio of the authoritative disaster data of the former Ministry of Land and Resources and the disaster bearing body of the threatened object as vulnerability, the vulnerability classification standard of the disaster bearing body of the threatened object was delimited according to the national sample value, and the geological disaster risk assessment was completed for 2869 county units in China combined with the geological disaster risk zoning. The results showed that there were 162 geological hazard high-risk units, 701 medium-risk units and 2006 low-risk units in China. The high risk areas of geological disasters are concentrated in Hengduan Mountain area, Wumeng Mountain area, Qinling-Daba Mountain area and Changbai Mountain area.
