| 摘 要： | 以湘江湖南段河流沿线地区为例，基于自然灾害风险评价的基本原理构建了洪水灾害综合风险值计算模型，即综合危险度和综合社会经济易损度的叠加。利用研究区全球数字高程模型(GDEM)数据、1971~2007年地面气象站观测数据和2008年社会经济统计数据等，借助地理信息系统(GIS)技术和地学方法，得到包含高风险区、较高风险区、中等风险区和较低风险区4个风险等级的洪水灾害综合风险区划图。结果表明：洪水灾害危险度最高的地区集中分布在湘江下游沿岸的湘阴县和长株潭地区；综合社会经济易损度最高的地区为人口密集的市区；湘阴县、长株潭三市和衡阳市市区危险度和易损度均较高，为洪水灾害高风险区。研究结果可为风险管理者和决策者提供量化的理论参考

| Abstract: | Risk zoning of flood disaster is the base of flood risk management.The advance in resolution of data can guide flood control,and flood insurance in a macroscopic view is available.Taking the catchment area along Xiangjiang River in Hunan Province as an example,and on the basis of elementary principles of natural disasters risk assessment,calculative model was established to obtain comprehensive flood disaster risk value which was computed by the integrated dangerous degree and comprehensive socio-economic v... |
