Application of Multi-Objective Fuzzy Pattern Recognition in Danger Evaluation of Debris Flow in Beijing Mountains


Danger evaluation of debris flow is the foundational work in debris flow forecast. Based on the surveying data and analysis of the developing characteristic, formation conditions and influent factors of the debris flow in Beijing Mountains, this paper establishes the evaluation indexes and the classification standards of the danger evaluation. With the multi-objective fuzzy pattern recognition method, the evaluation model is also established. With this model, the 15 debris flow valleys in Huairou County are evaluated. The result is consistent with the field surveying result, which proves that the model represented by this paper is feasible and effective, and the results can reflect the actual situation. Thus, the multi-objective fuzzy pattern recognition method can be one of the methods to evaluate the danger grade of the debris flow.
