中文摘要：

本文以呼伦湖为例，利用TOPEX／Poseidon测高卫星（1993～2002年）的GDR和WDR数据以及Jason-1（2002～2005年）的GDR数据对湖泊水位变化进行研究，得到湖泊水位异常的变化趋势。通过利用小波分析的方法对卫星测高获得的湖水位异常时间序列分析，得出了呼伦湖的水位年际变化周期，证明了利用卫星测高进行卫星测高监测湖泊水位变化的可行性。

英文摘要：

The altimeter data of TOPEX/Poseidon and Jason-1 over Hulun Lake are analyzed. The variety trend of lake level variations can be obtained. Time series of lake level anomaly from TOPEX/Poseidon and Jason-1 are studied using the wavelet analysis. By analyzing the wavelet coefficient diagram, the annual lake level variation of Hulun Lake is shown, which proves the ability for satellite altimetry to monitor the lake level variations.
