典型冰湖溃决泥石流成因分析及危险性评价体系探讨

Discussion on causes analysis and risk assessment system the typical glacial lake outburst debris flow

以高分辨率遥感技术为主要手段,结合地面调查,开展典型冰湖溃决泥石流灾害调查。文章通过对日喀则地区20个冰湖的调查资料,分析其成因机理,建立冰湖溃决泥石流危险性评价模型进行评价,评价结果与实地调查基本一致。

With high resolution remote sensing technology as the main method, combining with the ground survey, we carried out investigation in the typical glacial lake outburst debris flow disaster. In this paper, through the investigation of 20 ice lakes in Shi- gatse area, we analyzed the formation mechanisms and established the risk evaluation model on glacial lake outburst debris flow and found out that the evaluation results were basically consistent with the field survey.
