Abstract: Spatial and temporal data of the major lake surface aera change in the mid-lower reaches of the Yangtze River were obtained and analyzed on the platform of geographical information system (GIS) by using digital topography maps and satellite remote sensing images(Landsat TM/ETM) in different periods of time. The results showed that： the total lake surface area in the mid-lower reaches of the Yangtze River reduced about2 544.51km2 from 1971 to 1988 ,and 1 151.97km2 from 1988 to 2000. This should due to both nature factors and human activity ,but the major factor was lake reclamation.

Key words: lake surface area, MNDWI, the mid-lower reaches of the Yangtze River, lake surface area, MNDWI
