摘要：Zhijin county is one of the areas with fragile geological environment and frequent natural disasters in China. In recent years, with the intensification of human activities, the geological environment has been continuously damaged, causing geological disasters of different scales and serious life threats and property losses to people. Therefore, the purpose of introducing this mathematical model is to make the data more intelligent and professional by combining the data of geological disasters in mathematics. Based on the geological disaster monitoring, warning and decision support system of Guizhou province, this paper takes Zhijin county as the research object and uses Oracle database to manage the data by building and designing data structure and data model. The results show that geological hazard assessment can not only provide reliable data for analysis and research, but also provide reference value for similar database construction: (1) to construct spatial data model to realize effective correlation between spatial data and business data. (2) spatial entity objects have the characteristics of multi-dimension and polysemy, and “relational-object” mathematical modelling is adopted.
