The three Gorges Reservoir is the largestwater conservancy and control projectin China. After the three Gorges Projectis completed,a 30 m high water-level-fluctuating zone (WLFZ) will appear along the two banks and the area of the WLFZ reaches about300 km². By using GIS and RS techniques,land resources in the WLFZ are analyzed and classified in view of climate conditions,water depth in the WLFZ,slope,and soil textures of the land. The WLFZ is classified into six land models: rock exposed regions model,softrock exposed regions model,moderate and gentle model,reservoir backwater area model,unique landscapes model,and island model. The classification of the WLFZ of the three Gorges Reservoir provides a theoretic basis and scientific methods of rational development.
