中文摘要:

青藏高原的内陆湖泊水位和冰川变化和其流域内冰川质量亏损对湖泊水位波动的影响及其贡献对水量平衡研究具有重要意义。以哈拉湖流域冰川为例，基于2000-2015年星载雷达测高资料和Landsat卫星多光谱遥感资料分别提取湖泊水位和面积变化；结合附近的托勒台站气象观测资料，进一步分析其水位波动变化原因和冰川亏损对湖泊水量贡献。结果表明：受年降水量和夏季降水量增加影响，哈拉湖水位呈增加趋势，但哈拉湖流域冰川亏损加速趋势不明显；与2000年相比，湖泊面积增加了（21.4±4.8）km²，湖泊水位增加了（1.68±0.26）m，相应的湖泊水容量增加了（16.1±0.3）×10⁸ m³水当量。流域冰川亏损量达对哈拉湖水量的贡献率为39.65%，降水量增加对湖泊水量贡献了22.82%。

英文摘要:

In order to calculate the glacier meltwater contribution to the inland lake water storage fluctuations in the Tibet Plateau, the water level and area is of great significance for the lake water balance in the basin. Taking Hala Lake valley glaciers for example,based on 2000-2015 satellite radar altimeter data and Landsat multi spectral remote sensing data,the paper respectively extracted the changes of lake level and area. Combined with the nearby Toler meteorological observation data, it further analyzed the fluctuation of water level change and glacier loss on lake water.The results show that impacted by the increase of annual and summer precipitation in Hala Lake basin, the water level of Hala Lake basin appears the increasing trend,but the glacier loss acceleration trend is not obvious.Compared with 2000, the lake area of Hala Lake has increased by (21.4±4.8) km² and the corresponding lake water level increased by (1.68±0.26) m which the lake water storage increased by (1.61+0.03) billion cubic meters. The contribution rate of glacier mass loss to lake water volume in the basin is 39.65%.The increase of precipitation contributes 22.82% to lake water volume.
