Abstract:
In the article, Taohu and Gehu Lake of Taihu drainage area were taken as examp les where land-use type changed enormously. The article used the statistic data of polderization in the Taihu drainage area which were acquired from the 1954～1981 aero data and the 3 timesLandsat data of 1979, 1991and, 2001 to extract dynamic land use information around the Taohu and Gehu Lake in 1954～1981, 1981～ 1991and 1991～2001, DEM was used to calculate the index of flow accumulation and the Landsat data were used to acquire the index of vegetable grow suitability and the index of building quantity. With the help of the three indexes and the APH method, the author can evaluate the suitability of restoring the lake from the land. At last the result of the studywas compared with the land use type in 1991～2001, and the app rop riate p lotwas chosen to restore into lake. The result of the estimate can p rovide the scientific basis for using the water and land resource around the lake in this area.
