Abstract: Activities of investigation and management of geological hazards in Three Gorges reservoir area involves a great amount of engineering projects, which produce huge data and documents in short time periods. An information system is in need, with which not only the demand from the basic working units is satisfied and the requirement raised for data management and analysis postprojects must be met as well. A pointsource information system, GeoHazard, is developed to fulfill the tasks described above. The system has a thematic database of pointsources as its core. Solutions for data acquisition based on a geographic base map, GISbased map production, visualized query upon maps and webbased remote data gathering are provided. A number of functions is implemented, which includes data input, graph and map produce, data storage and management, computeraided output. The system supports geohazard investigation activity as a whole. It features with the standardization of terminology, code and metadata, integrated management of all types of data and documents, and visualized data analysis, query and presentation.

Key words: geological hazards, geotechnical investigation, Three Gorges reservoir area, point source, information system
