摘要随着全球性的温度升高，藏东南地区温度也逐年升高，导致近期内西藏林芝地区内发生了多次灾难性冰川泥石流灾害。为此，选取林芝地区的波密县至易贡段冰川泥石流为研究对象，分析得到研究区冰川覆盖面积年平均缩减率为2.93%，且由统计分析发现冰川覆盖面积的变化特征与泥石流的流域特征相关。由克拉伯龙–克劳修斯方程与热化学方程分析得到冰川、积雪的融水强度等。通过流体力学与静力学分析冰碛物有效粒径d10的起动和其局部剪切破坏与冰川、积雪融水强度和降雨强度的关系，为冰川泥石流的预防等提供一定的参考。

Abstract：Along with the increased temperature of global，the temperature of South-East Tibetan has rose year by year which led to many disastrous events as glacier debris flows in the history of Nyingchi area. Therefore，the glacier debris flows located in Bome to Yigong in Ningchi as the research object was investigated and analyzed，and discovered the reducing-rate of the glacier area in studied area was about 2.93%，and the variation characteristics of glacier area related to the drainage basin of debris flow by the statistic-analysis. For this purpose，the intensity of meltwater was got by the Clapeyron-Clausius equation and thermochemical equation，and the starting characteristics of the effective diameter d10 and local shear failure of the glacial tills was studied，the relation between temperature and raining conditions was established when the debris flow out-broken，according to statistics and theoretical analysis of hydromechanics and statics，to provide certain reference for the prevention of glacier debris flow.
