摘要
///According to the diversity, variability, complexity of the geological environment and conditions in the Taohe River valley, Min County, debris flow gully formed a more complicated disaster “fuzzy” system from the formation and development to the disappearance by a lot of factors influence. This paper introduced fuzzy mathematics theory into the risk evaluation of the debris flows. This paper used fuzzy comprehensive evaluation method developed by Liu Xilin, Gongxue, and Chen Wei, and selected eight risk factors such as valley relative elevation, degree of vegetation cover and completed single gully risk assessment about the 10 debris flows in the Taohe valley of Min County.
