阐述了泥石流灾害风险的现状及内容，从区域和单点两个角度综述泥石流风险评估方法。研究现状表明：泥石流风险的计算公式得到广大学者的普遍认同，泥石流风险评估方法比较成熟；但在泥石流风险权重系数的确定、发生概率计算及易损性的研究尚需深入。因此，在今后的评估研究中，需要加强这些方面的研究探索，进一步提高泥石流风险评估结果的可信度及实用性。%This paper expounds the present’s research situation of debris flow risk assessment as well as the content of debris flow risk assessment,including regional and single debris flow risk assessment methods.It was shown that the calculation formula of debris flow risk had been popular and the methods of risk assessment had been established.However,some problems still exist,such as weight of debris flow,probability and vulnerability. Hence,it must be necessary to strengthen research in these aspects in the future,which might improve the reliabili-ty and practicality of debris flow risk assessment.
