Jianghan Plain where Jianghan lake group locates in is an important production base of commodity, grain, cotton and oil, and is a typical ecological vulnerable area, with situation of severe flood and water logging. Jianghan lake group plays an important role in regulating and storing the flood for Jianghan Plain as well as Yangtze River. It is significant to analyze the evolution of lakes combined with the historical data. This paper does comparative analysis based on the previous studies on the lakes in this region and the remote sensing image data during 1995-2010. The results show that the...
