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.

Key words： engineering geology glacier debris flow starting mechanism Nyingchi area
