摘　　要：概述了国内外泥石流起动机理研究(实验研究及理论研究)的现状,在归纳总结前人研究成果的同时,分析其研究的不足,同时提出泥石流起动机理未来的研究方向。未来的研究应该以土力学及水力学、渗流力学等学科为基础,揭示泥石流土体的动态变化过程,从静态向动态、从单因素向多因素、从定性向定量方向转化,并结合土体的动态破坏过程及需水条件构建泥石流起动的模型。泥石流起动机理的研究不仅可以为泥石流的预测预报提供科学依据,同时又可以推动泥石流学科的发展。The current research situation of debris flow initiation mechanism（experimental study and theory research） is summarized.On the basis of induction and summarization on the previous achievements,shortcomings of the previous researches are analyzed and the future research directions of debris flow initiation mechanism are proposed.Founded on soil mechanics,hydraulics and porous flow mechanics,etc.,the study in the future should reveal the dynamic process of debris flow from static to dynamic,from single factor to multi-factor,from qualitative research to quantitative research,and finally combining with the damage process and water condition to establish the initiation model of debris flow.Research on debris flow initiation mechanism can provide scientific basis for debris flow prediction,and promote the development of debris flow discipline at the same time.
