| 摘 要： | 通过对湖泊补给水量的分析,博斯腾湖2002年前后水位由高向低的转折变化是由开都河径流变化造成的.对2002年前后天山南北其它主要湖泊的水位和河流径流变化作了比较分析结论.由于山区河源径流补给组成不同,表现出在同一中亚气候背景下,即2002年前后该地区气温降低而降水东西各有差异,使得天山西段受降水补给为主的河流,2002年后径流仍有增加,具体反映在伊塞克湖、巴尔喀什湖等水位持续上升和托什干河等径流的偏丰;而天山东部的开都河,受降水减少和气温降低对冰川变化的双重影响,2003年以来径流明显减少,导致博斯腾湖的水位持续下降.

| Abstract: | Considering the lake water level change,in this paper water balance in the Bosten Lake is analyzed,and found that the runoff change in the Kaidu River played an important role in this process.In view of the impact of climatic change on hydrology,a comparing analysis of lake water level and relevant runoff change was made around the Tianshan Mountains since 2002,and revealed that different hydrological change in different catchments can be attributed mainly to the difference in the meltwater proportion at the upper reaches under climate change background.The runoff has decreased in the rivers with more meltwater supply due to low temperature since 2003.At last a brief discussion is made on the hydrological development trend in the lake. |
