- Abstract:
-
We collected data and carried out field survey in Bailongjiang River Basin, and selected landform factors and geological factors as the debris flow risk assessment indicators, used the grid unit as the evaluation unit, and analyzed the study area power environmental factors. Based on information entropy and AHP model study area debris flow risk assessment model was established, respectively. The result showed that based on information entropy model of debris flow risk level and the level of risk based on AHP model distribution appeared similar on the whole, there were differences between the local patterns, but landslide distribution based on the evaluation of information entropy model partition is more consistent with the actual results. Thus, within the scope of the large area, the debris flow risk assessment partition based on information entropy model has good plasticity and practicability, and plays the important role in geological disaster prediction.
