The natural factors affecting the occurrence and development of debris flow are discussed in this paper. Some mathematical schemes to evaluate the disaster of debris flow are also studied, to establish an indicator system for existing debris flow disasters. We individually establish a disaster evaluation indicator system from three aspects including point, line and area, to evaluate the disaster of debris flow, and to determine the parameters for relative indictors in disaster evaluations. Meanwhile, quantity scoring method and analytic hierarchy process are adopted to perform consistency test on its results. So a more accurate evaluation of the degree of risk for some specific section or area can be acquired. It is verified to provide scientific direction of the construction of highway and disaster prevention.
