Abstract The Three Gorges Reservoir Area is subject to frequent human activities that are adversely affecting the
fragile balance of ecosystem dynamics. The potential effects of Three Gorges project on ecological environment have
always aroused much attention. With the aid of RS, GIS, GPS and network technique, the authors applied DEM,
adjustment of orthographic reflection for images, interfusion of multi-source image data and multi-layer information
extraction to performing comprehensive monitoring of the ecological environment of the whole reservoir area from
middle 1980’s to late 1990’s. On such a basis, the project “The GIS System for Remote Sensing Ecological
Environment Dynamic Monitoring of Three Gorges Reservoir Area” has been developed and completed with the aid of
ArcGIS software platform.
