Abstract: Based on the technology requirements of geological survey of geological hazard control engineering for the third period of Three Gorges reservoir area, this paper designs landslide stability system of Three Gorges reservoir area with the technology of GIS, to support quantitative evaluation of stability for alarm conducting system. It elaborates the construction target and details of the landslide stability evaluation system of Three Gorges reservoir area based on GIS, places great emphasis on analyzing the global design, logical structure and functional module design of the system, and shows the implementing interface of the system.

Key words: GIS technology, landslide, stability evaluation
