摘  要：
应用1964—2014年的12期多源遥感数据,对天山西部的别珍套山冰湖进行面积变化制图,从数量和面积分析了冰湖的时间变化过程,从规模、海拔、坡向、类型等方面分析了冰湖变化的空间特征,并结合气象资料与冰川动态探讨湖泊变化的驱动因素。结果表明:多时期的遥感数据能更好地描述冰湖由数量减少、面积萎缩到数量增加、面积扩展的趋势,其时间段分别为1965—1978年和1978—2014年。冰湖在规模上普遍偏小;在海拔上,3 300~3 500 m处冰湖分布最多,也是冰湖变化最为显著的区段;在坡向上,冰湖数量及面积变化显著的区域为北坡,这与冰川的分布一致;在类型上主要以冰碛湖为主。冰湖的时间变化过程很好地响应了区域降水和气温的变化,而冰湖在空间上的变化差异与冰川直接相关。

摘  要：
Glacial lakes are important and the sensitive indicators of climate change. Mapping of these lakes and their spatiotemporal change is of a great importance to understand the alpine climate change and the change of glacial lakes related to hazards. In this paper,12 time series of multi-source remote sensing images were used to map the change of glacial lakes in the Biezhentao Mountain and the west Tianshan Mountains,and the spatiotemporal change of the glacial lakes was analyzed from the sizes,elevations,slope aspects and lake types. Meteorological and glacier data were also used to discuss the driving forces of lake change. The results showed that the multi-temporal remote sensing data performed well in describing the temporal processes of lake change. Change of the glacial lakes in the Biezhentao Mountain could be divided into two different stages: the lakes shrank during the period of 1965-1978,but they expanded during the period of 1978- 2014. Compared with other glacial lakes in the Himalayas,these glacial lakes are much smaller,and most of them are located in an elevation range of 3 300 ~ 3 500 m. Glacial lakes in this elevation range change fast,especially on the northern slope,which is consistent with the distribution of glaciers. There are 4 types of glacial lakes in the study area,and moraine lakes are the main type. Glacial lakes with glacier melting water supply,such as moraine lakes and cirque lakes,change more significantly than those including the erosion lakes and valley lakes without glacier melting. There was a good correlation between the meteorological data and the change of glacial lakes in the last 50 years,and the expansion or shrinkage of the glacial lakes responses to climate change from the dry-cold trend to the wet-warm one.
