综合不同的泥石流评价因子对泥石流危险性进行了研究，利用地理信息系统（ GIS）来计算潜在的泥石流危险区域。选取虹口乡高原村与庙坝村共处坡面为研究区域，在ArcGIS中生成研究区域的坡面立体图。选取适当的评级指标，确定了流域内主要的泥石流影响因子。采用层次分析法得出各主要因子的权重值，将各因子划分为五个不同等级，并分别对各个因子进行数值化和归一化处理。利用ArcGIS形成各评价因子专题层，再分别给不同评价栅格赋权重值，最终运用叠置分析与插值分析得出研究坡面的不同色带所表示的危险等级区划图，从而实现单坡面泥石流危险性的评价。

The thesis studies the risk of debris flows by synthesizing different evaluation factors of debris flows , and uses GIS to calcu-late the potential zone in danger of debris flows .Taking the slope shared by Gaoyuan village and Miaoba village in Hongkou town as the area for study , the stereogram of the slope in the study area is generated in ArcGIS .Selection of the appropriate index of evaluation determines the main influence factors of the debris flows in the watershed .By using the analytic hierarchy process to work out the weight value of the main factors , five degrees are divided and then these factors are processed with the numeralization and the normali -zation method separately .The thematic overlaps of all the evaluation factors are formed by using ArcGIS , and then the weighted values are assigned to different lattice cells respectively , at last, the block plan of danger levels indicated by the different color zones of the slope is worked out by adopting the overlapping analysis and interpolation analysis so as to realize the risk assessment of debris flows on single slope .
