摘要湖泊作为干旱和半干旱地区最主要的水资源，不仅是该地区气候变化的指示器，同时还是揭示气候 变化与区域响应的重要信息载体。湖泊水位的变化不仅明显、易观测，且能够清晰地记录湖泊波动，为 研究湖泊区域气候变化以及预报湖泊灾害气象提供科学依据。本文以中亚为研究区域，巴尔喀什湖和伊 塞克湖为研究对象，利用 Topex/Poseidon、Jason-1/2 卫星测高数据分别对两个湖泊近 20 年的水位进行 动态监测,发现两个湖泊的水位均呈上升趋势。通过分析两个湖异常年水位和月水位的时间序列，得到 两个湖泊湖面高度年际变化、季节性变化及其变化周期。并分析引起这些变化的驱动因素，其中巴尔喀 什湖的水位主要是受气候变化和人类活动的双重影响，而伊塞克湖水位则受降水量和入湖径流量的影 响。89052

ABSTRACT Lakes are the most important water resources in arid and semi-arid areas and are also indicators of climate change in the region。 They are important information carriers for revealing climate change and regional response。 The change of lake water level is not only obvious, easy to observe, but also can clearly record the lake fluctuation, in order to study the lake area climate change and forecast the lake disaster weather to provide scientific basis。 In this paper, the water level of two lakes in the past 20 years is dynamically monitored by using Topex / Poseidon and Jason-1/2 satellite altimetry data in Central Asia, Balkhash Lake and Issyk-Kul Lake as the research object。 By analyzing the time series of the annual water level and monthly water level of the two lakes, the interannual and seasonal changes of the two lakes and seasons are obtained。 And analyzes the leading factors that cause these changes, in which the water level of the Balkhash Lake is mainly affected by climate change and human activities, while the water level of    Issyk-Kul Lake is mainly affected by precipitation and lake runoff。
