Debris flows in the Beijing Mountains-Patterns of development and prediction of regional risk

摘要

Debris flows are the most serious geological hazard in the Beijing Mountains. This paper discusses characteristics of the distribution and formation of debris flows based on field survey data, and chooses nine factors that are closely related to their formation. A method of fuzzy comprehensive evaluation is used to evaluate the degree of danger from debris flows. The results are compared with the field survey and provide a scientific basis for mountain development planning and disaster control.
