摘要:
在气候变化的影响下,喀喇昆仑山叶尔羌河冰川突发洪水近几年频繁发生。2009-05—09,利用中国环境减灾卫星(HJ-1A/1B)影像,对叶尔羌河上游冰川突发洪水的源头进行了动态监测。在克亚吉尔冰川末端发现了冰川阻塞湖,并监测到其不断扩大。2009-08初该处冰川湖突然消失,同期影像显示其消失后,河谷中残留大量冰体,与往年情况差异巨大。结合相关水文记录及历史资料分析认为,极有可能是冰川末端突然前进(跃动)使冰川坝遭到破坏,导致冰川阻塞湖泄水。由此推测克亚吉尔冰川发生了罕见跃动现象,但需要进一步研究验证。
Abstract:
Under the influence of climate and glacier changes, Glacier Lake Outburst Floods (GLOFs) occurred frequently in Yarkant River, Karakorum,China, in recent years. Using China Environment and Natural Disaster Monitoring Satellite images (HJ-1A/1B), source of floods in upstream Yarkant River was under dynamic monitoring from May to September in 2009. During this period, an expanding icedammed lake was found in the glacier terminus of Kyagar. However, in early August the icedammed lake suddenly disappeared, leaving a large number of ices in the river valley. This phenomenon is significant different from previous years. Related hydrological records and analysis of historical data show a sudden advancing of glacier terminus damaged the ice dam, leading to the leak out of icedammed lake. The results suggested that infrequent glacier surging occurred in Kyagar glacier, and further monitoring will be conducted near future.
