A Fuzzy Appraisal of the Risk Degree of Debris Flows

WANG Xin (Dept.of Geography,Chongqing Normal University , Chongqing 400047,China)  
Based on the existing achievements of the studies of debris flows,their features of activities and their victims,the paper puts forward six appraising norms.Taking into account the advantages of fuzzy mathematics in the practical application and using a gradation analysis to determine the appraising norms of risk degrees,it sets up a model of fuzzy appraisal of debris flows and finally examines it with a successful example of its application.The result shows that this kind of appraisal is feasible and significant for the understanding of the features of debris flows and their prevention.
