摘要：

湖泊水位的变化对区域气候变化响应敏感,可客观反映该地区水资源的时空变化,青藏高原的大部分湖泊缺乏实测水位资料,测高卫星的广泛应用为无资料区水位变化监测提供了一种新的有效技术手段。论文以扎日南木错为研究对象,利用多源卫星测高数据,获取该湖泊1992—2012 年的水位序列,分析其20 a 来水位的动态变化特征,并与其他数据源获取的水位序列对比。研究表明,1992—2012年,扎日南木错水位上涨了0.786 m,1999年前,水位以0.132 m/a速度下降,1999—2012 年水位以0.144 m/a 速度上升,总体呈现先下降后上升的趋势,与其他数据源获取的水位序列呈现的变化规律一致,且尤其是2000 年后,扎日南木错春冬水位比夏秋水位变化幅度更剧烈。

Abstract:

Lake Level variation is an important indicator of regional and global climate and environment. It can reflect the water mass balance of a basin. There is lack of continuous observations of lake level for most lakes in Tibetan Plateau. However, the satellite radars provide a new and effective method for lake level detection. In this study, lake level changes between 1992 and 2012 of Zhari Namco were monitored using multi-altimetric data, and the obtained time series of water levels are compared with those from other resources. The results show that the lake level of Zhari Namco rose by 0.786 m in total in the period of 1992-2012, but it shows the tendency of descending before 1999 by the rate of 0.132 m/a and then rose after 1999 by the rate of 0.144 m/a. The results are in agreement with time series of water level for other resources. Moreover, the amplitude of lake level variation is more intensive in spring and winner than in summer and autumn, especially after 2000.

Key words: inland lake, Zhari Namco, lake level variation, satellite altimetry
