摘要：Taking the Yanbian Prefecture as the study area, this paper selects 8 influencing factors: elevation, slope, slope direction, precipitation, river, lithology, fault and land use. Taking 163 debris flow points as sample data, information quantity method and GIS platform are introduced to calculate the information amount of each influence due to sub classification. The risk assessment and analysis of debris flow were carried out, and the risk assessment and analysis map of debris flow in Yanbian was drawn. The results show that the areas where the debris flow hazard is more dangerous are in good agreement with the historical debris flow, and the accuracy of the methods and factors used in this paper is verified.
