Taking the Beijing-Tianjin-Hebei region as an example, this article puts forward a method of geological hazard risk assessment. By calculating the level of threat of geological hazards and vulnerability of hazard-affected bodies first, we evaluated the geological hazard risk of counties and districts by qualitative comprehensive assessment. Vulnerability of hazard-affected bodies is composed of population vulnerability and property vulnerability, which are represented by the rate of deaths and rate of direct economic loss caused by geological hazards. Combing with the data of geological disaster situation during 2001-2015 from the Ministry of Land and Resources and taking into account the 1950-2000 disaster data, we proposed the classification standards of population vulnerability and property vulnerability. These standards and calculation were applied in the Beijing-Tianjin-Hebei region. The result shows that the overall geological hazard risk is low. Only six areas—Laiyuan, Laishui, Wuan, Qinglong Manchu Autonomous County, Shijingshan, and Yanqing—show medium risk among the total of 204 assessed county and district units. The rest of the counties and districts are in the low risk area, which is in agreement with the reality. The method proposed here is simple and easy to use, and data can be acquired continuously. The spatial difference assessment result can be used to support the disaster prevention and risk reduction efforts and spatial planning and management.
