Abstract：Regional geological surveys are a basic work for disaster prevention and mitigation management. Based on the actual field survey and the geological hazard analysis, the GIS technique, the database technique and the multi-sources data technique are applied to acquire and analyze the geological hazard information, as a bottleneck in the regional geological hazard investigation. According to the geological industry standard, the characteristics of geological hazards are analyzed, and the heterogeneous data sources including the basic geographic data, the hazard feature data and the correlative multimedia data are normalized. Moreover, the connections are marked for special data and hazard characteristic data. Consequently, a special topic database is built for geological hazards by the ArcSDE and SQL Server management platform. And then, with ArcGIS's open development environment, the data acquisition and analysis system for the county regional geological hazards is successfully constructed by the Visual Studio.Net(C#) and ArcEngine technology. The software system, consisting of function modules of the map operation, the information importing and editing, the inquiry statistics, the hazard analysis and evaluation, the mapping output, can meet the demands of the geological hazard data acquisition and analysis. Furthermore, the above work not only provides a computer platform for rapidly acquiring and scientifically managing the geological hazard information, but also offers a technical support for the regional hazard analysis.
