熵值-可拓理论在泥石流危险度评价中的应用

摘要

运用熵值法对泥石流危险度评价因子进行了客观性赋权，避免了主观赋权法在权重值评判过程中，人为因素对评判结果影响较大的不利之处，并通过建立基于可拓学理论的泥石流危险度评价模型，对可拓学模型的评价结果进行了验证，结果表明该方法与实际情况吻合程度较高。%By using the entropy of weights on the objectivity of the debris flow hazard assessment factor,avoid the subjective weighting method in the evaluation process,the disadvantage influence of human factors on the evaluation results. Establish extension of debris flow risk degree assess-ment model and verify the evaluation results. The results show that the method has high degree of agreement with the actual situation.
