利用卫星测高资料监测长江中下游湖泊水位变化

Monitoring Level Fluctuation of Lakes in Yangtze River Basin by Altimetry

利用Envisat 1卫星的GDRs数据,根据适当的数据编辑准则,进行了必要的地球物理改正之后,研究分析了长江中下游鄱阳湖、洞庭湖、太湖、巢湖的水位变化及其与气候环境的关系,为长江流域水位变化与气候变化的长期性研究提供了一种有效的手段和方法。

The flood and disaster usually happen in Yangtze River, especially in the middle and lower reaches, for the special geographic position and climatic environment. The Poyang Lake, Dongting Lake, Taihu Lake and Chaohu Lake have the capability to regulate and control the flood in Yangtze River. The level variations of these four lakes and its relation with climate are studied using Envisatl GDRs data based on date editing rule and some geophysical corrections. Altimetry is a valid methods to investigate the long time level variation of Yangtze River.
