波密地区冰湖溃决灾害调查及分布现状研究

Research on the Investigation and Current Status Distribution of Glacial Lake Outburst Disaster in Bomi Region

西藏自治区有记录以来,发生安全事故的冰湖溃决事件共计27起,其中藏东南地区占比3/4以上。波密地区地处藏南谷地与藏东横断山脉的高山峡谷区的过渡段,属深切割高山河谷地貌,属典型藏东南地貌。论文通过对波密县1∶5万地质遥感图的解译,并结合波密地区区域遥感数据及气象数据,研究波密地区冰湖区域性现状及典型冰湖溃决的成因机理,从而为该区域冰湖相关问题提出预防治理的对策方法,从而促进波密地区经济快速、稳定地发展。

Since records began in Tibet autonomous region,a total of 27 glacial lake outburst incidents have occurred,of which more than three-quarters have occurred in southeast Tibet.Bomi area is located in the transition section of the mountain valley between the south Tibet valley and the hengduan mountains in east Tibet.It belongs to the deep-cut mountain valley landform,belongs to the typical Tibetan southeast landform.Based on the interpretation of 1∶50000 geological remote sensing map in Bomi County,this paper combines the regional remote sensing data and meteorological data in Bomi County,and studies the regional status of glacial lakes in Bomi County and the cause of formation of typical glacial lake outburst,and then proposes the countermeasures for the prevention and treatment of the problems related to the glacial lakes in this region,so as to promote the rapid and stable economic development of Bomi region.
