摘要
Abstract
Based on detailed analysis of the debris flow formation conditions,ten assessment factors are selected from five different aspects such as geology,terrain,vegetation cover,people’ s activity and trigger factor to set up a suitable debris flow risk assessment system for Southern Anhui.All factors are standardized and the analytic hierarchy process (AHP) is used to give weight to each factor. Based on powerful spatial analysis and data processing function of GIS,the risk grade diagram is generated.To examine the accuracy of assessment system,this paper uses debris flow warning diagrams as benchmarks and proves that the results are consistent with the actual situation.关键词
