| 摘 要： | 基于洪水灾害系统特征,提出了区域洪水灾害易损性概念,认为洪水灾害易损性是指在一定社会经济条件下,特定区域各类承灾体在遭受不同强度洪水后可能造成的损失程度;建立了包括致灾因子、孕灾环境、承灾体属性和社会救灾能力在内的洪水灾害易损性评价指标体系;基于层次分析法,构建了目标层为区域洪水易损性,准则层为致灾因子、孕灾环境、承灾体和社会救灾能力,指标层为降水、地形、植被、生命、环境与经济等要素的区域洪水灾害易损性评价模型与评价方法。为便于决策,将易损性分为1～10共10个等级,等级越大,表明区域洪水易损性越高。

| Abstract: | Based on analysis of flood disaster system, the concept of regional flood vulnerability is defined, which means the capacity to resist flood of all kinds of disaster bearers at a region. The indicators of flood vulnerability including disaster environment, disaster drivers, disaster bearers, and disaster bearing capacity of society are introduced. A model and method of regional flood vulnerability assessment is designed by analytic hierarchy process (AHP) method, with regional flood vulnerability as the target layer, disaster environment, disaster drivers, disaster bearers and disaster bearing capacity of society as the criteria layer elements, and precipitation, topology, vegetation, life, environment and economy as the indicator layer elements. In order for decision-making, the vulnerability is classified into ten grades (1～10), with greater grades indicating higher regional vulnerability to flood. |
