基于流域系统地貌超熵的泥石流危险性定量评价

摘要

该文探讨了流域地貌系统的超熵理论对于泥石流演化阶段划分的影响，并应用于泥石流危险性的定量评价。通过四川省川西高速公路沿线10条泥石流沟进行实例分析，评价结果表明，流域地貌系统超熵理论能较好地应用于泥石流危险性评价中，具有一定的客观性与可操作性。%Effect of superentropy theory in basin morphologic system on the division of debris flow evalution phases is dicussied , and applied to the risk assessment of debris flow.Through the analysis of the ten debris flow gully along the Western Sichuan txpress , it is shown that the theory can be applied in the risk assessment with objictivity and operability .
