- Abstract:
- At present, there have many methods for the debris flow harzard assessments, such as fuzzy mathematic, artificial neural network, GIS etc. But, these methods are also short of nonlinearity catastrophe characteristic from quantitative change to qualitative change among systems. We use Catastrophe Progression Method to evaluate the harzard of the six valley units in the Min County of Gansu Province combining catastrophe theory with fuzzy mathematics.This paper adopts the main steps and ideas of a method using catastrophe theory called catastrophe progression method and only considers the relative importance of the index, so the method avoids the subjectivity for weight decision and works simply. The resuts are found to be coincident with practical situation, so it proves the catastrophe progression method works well at the aspect of the danger evaluation to the debris flow according to the factual case.
