GIS - based regional geological disaster information management system in the China Geological Environmental Monitoring Institute , Shandong Province, Laizhou City Geological Hazard Division and project funding on the basis of existing research , analysis and field verification results , the use of GIS techniques to spatial data as the main material , \The system for regional disaster prediction , forecasting and control not only of theoretical significance , but also has important practical significance . The thesis focuses on the specific requirements and objectives of the regional geological information management system requirements, describes the method for establishing regional geological disaster information management system based on COM technology , the choice of Access established external property database , and the Visual Basic environment using MapObjects control the development of the system user interface , and the overall design of the system is the database of the system , structure and main function modules . The study focuses on the collapse , landslides, mudslides , ground subsidence , five ground fissure disaster occurred in the region based on the law , the development of the regional geological disaster information management system to generate geological disaster point distribution layer , administrative divisions , transportation , water system , geological boundaries of graphics files. External properties database of debris flow and the space of five hazard database , according to the distribution characteristics of geological disasters in the space , to provide a comprehensive analysis and processing functions of the human-computer interaction , regional geological disaster information management , prevention and early warning .
