摘要

Landslides and debris flow often cause serious economic losses and casualties. In recent years, the occurrence of geological hazards such as landslides and debris flow in Yunnan has been increasing. According to various factors causing landslide and debris flow in Yunnan Province, this paper selected rainfall, slope, fault, earthquake, lithology, and vegetation coverage as assessment factors. Combined AHP and GIS analysis method, single-factor risk assessment and comprehensive assessment method are used to evaluate the risk of landslide debris flow in Yunnan Province. The results show that nearly 30% of Yunnan has a high incidence area of landslide and debris flow. Moreover, the spatial distribution of landslide and debris flow has the general characteristics of "west less than east, north less than south, and less middle."
