| Abstract: | Lanzhou urban has become a famous debris flow area in the upper reaches of Yellow River because of steep and frangible topographic, active geotectonic, soft and hard rock mass alternation, rainfall in a very short period and unreasonable development. This paper constructs an evaluation model on debris flow disaster by means of surface development degree of debris flow catastrophic body morphological, analyze valley debris flow development trend of Lanzhou urban areas applying entropy theory, and indicates the shortcomings of the debris flow evaluation model. |
