在详细分析泥石流形成条件的基础上，从地质、地形地貌、植被、人类活动和触发因子等5个方面选出10个评价指标，进行指标规范化处理，并运用层次分析法确定各指标权重，建立了符合皖南地区特点的泥石流危险性评价体系。在地理信息系统（ Geographic Information System， GIS）强大的空间分析与数据处理功能支持下，输出皖南地区泥石流危险性分级图。通过与泥石流预警图对比，评价结果与实际情况具有较好的一致性，证明了该评价体系的正确性。

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.
