| 摘 要： | 卫星测高为内陆水域水位变化的实时和连续监测提供了一种高效的技术工具．但是这种应用受到数据点覆盖稀疏的限制。利用Jason-13年（2002-2004）GDRs测高数据作简单的数据编辑，并进行必要的地球物理改正．最后得到内蒙古地区呼伦湖水位变化的时间序列。呼伦湖地区由于近年来持续干旱，水位呈现明显的下降趋势．年平均下降约0．3～0．5m。在一般的内陆水域．水位变化主要取决于降雨量和蒸发量，所以，根据卫星测高所得的水位变化信息．可以为区域气候变化的研究提供一种全新的技术与方法。 |

| Abstract: | The satellite radar altimetry,a new method and technology, provides an efficient technical tool for real time and continual monitoring of the water level of inland lake. However, such application is limited due to the sparse data coverage on inland lakes.We investigate the water level variation of Hulun lake by use of Jason-1 data through some data editing rules and several geographical corrections. The lake located in Inner Mongolia region is the fifth largest one in China. The numerical results show that the water level of Hulun Lake has a continual drop about 0.3-0.5 m/a because of the drought climate in recent years. We can investigate the regional climate change with the water level information resulted from altimetry.As the water level variation of inland lake depends on precipitation and evaporation. |
