  • It has been nearly 40 years since the surveying, monitoring, studying and controlling on geo hazards had been started in the Three Gorges area on Changjiang River, and it contributed more to the construction of the Three Gorge projects and the protection in ecological geo environment this region. However, it has been found that there were some shortages in previous works in such as less guidance to directly developing the socil economy and to constructing the immigration project, less consideration of ecological environment,and backward techniques. In this paper, the authors suggest a new thought of surveying and studying the geo hazards in the Three Gorges region (include 19 counties and cities),i.e.. The work must be centered at the conservation environment for human existence and settlement of residents migrated from the project area; the modern monitoring techniques and analysis methods must be applied. Basing on the comprehensive survey, we can develop a geo hazards geologic information system (GGIS), which contains digital spatial database and multiplicity of map sets. Some quantitative indexes such as development degree, risk degree and damage degree are used as a base for comprehensive assessment, classifying, monitoring and forecasting geo hazards. Then a monitoring and forecasting net work system consisting of RS, GPS, GGIS and public prevention system . Our top target is to realize the development protection of geo environment and the qsprediction and reduction of geologic hazards.
