| 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 larg... |
