摘要
In light of the complex uncertainty of the debris flows, fuzzy mathematics is used to make a comprehensive evaluation. Human activities, geological, topographical and climate conditions are analyzed in establishing a fuzzy mathematics evaluation model. Factors are classified and their weights are defined. The studies on Qiujiagou, Tianxugou, and Changpogou gullies show that, in terms of debris flow susceptibility, Qiujiagou comes first, Tianxugou second, and Changpogou third.
