摘要： 区域洪水灾害风险评价是洪灾评估和管理的重要内容。依据灾害系统理论,利用GIS方法,综合分析了渭河下游对洪水灾害有影响的降水、地形、水系、过境洪水和防洪工程等自然致灾力和孕灾环境的影响度,以及承灾体遭受不同强度洪水可能损失程度的易损性影响度,运用层次分析法和因子叠加法,从自然和社会属性两个方面对洪灾风险进行了综合评价和分析。结果表明:研究区洪水灾害风险整体上以渭河下游干流为中心逐渐向两边递减,即离主干河流越近,风险越高,反之越低;从行政区划上来看,西安市城区和临潼区基本处于高风险区,而华县、华阴市和潼关县基本处于低风险区。

Abstract: Regional flood disaster assessment is an important content for flood disaster estimate and management. According to disaster system theory, using GIS method, through comprehensive analyzing some impact degrees of factors to flood disaster, such as rainfall, terrain, water systems, passing flood and flood prevention projects, as well as impact degrees of the factors to potential losing extents when encountering flood disaster, ecological risks of flood disaster were assessed and analyzed synthetically by applying to analytic hierarchy process and factorial overlay methods from two sides of natural and social attribute. The results show that risk of flood disaster declines gradually from center to two sides around main stream of the lower reaches in the Weihe River as a whole. That is, the closer to main stream, the higher the risk. From administrative divisions, Xi’an City and Lintong District are in high risk zones, Hua County, Huayin City and Tongguan County are in low risk zones.
