Abstract
The research situation on risk assessment of debris flow was reviewed in this paper. At first, the distribution of debris flow in China was studied. And then the evaluation methods were introduced, including the Gray Forecast Evaluation Method the Artificial Neural Network Evaluation Method, the Information Entropy Theory Evaluation Method, Fuzzy Comprehensive Evaluation Method, the RS and GIS Evaluation Method and the application of Analytic Hierarchy Process in risk assessment of debris flow. Finally, the difficulties in risk assessment of debris flow has been discussed. From the study of this paper, there is a more comprehensive understanding on the risk assessment method of debris flow, which will be used as a reference in the study of the risk assessment method of debris flow in the future.
