中文摘要：
我国东南沿海地区经济发达,暴雨洪涝灾害损失严重,需要进行风险区划和风险评价.选取东南沿海的上海、浙江、福建、广东4省市为研究区域,统计1951—2000年共50 a的暴雨洪涝资料,利用Arcview的空间分析和叠加功能,将不同阶段各省市的受灾分布图进行叠加,得到了东南沿海地区暴雨洪涝灾害风险性评价图.由此评价图知,上海市和福建省的大部分为高风险区,浙江省大部分是较高风险区和中风险区,广东省主要为中风险区、较低风险区和低风险区.该评价结果与东南沿海地区的实际情况基本吻合.
英文摘要：
Southeast coastal area of China,economic developed area,has suffered serious losses from storm flood disasters.So it is necessary to zone and assess the risk.Selecting Shanghai,Zhejiang,Fujian and Guangdong Province which locate in the southeast coastal area of China as the research area.Firstly,through 50 years storm flood disaster′s statistical data from 1951 to 2000,distributions of damaged at different stages had been obtained.Then,a primary zoning and assessment of storm flood risk for the southeast coastal area had been studied using Arcview GIS platform with strong function on space analysis and overlap,the disaster distributing charts of every province or city were overlaped at different period,the chart about storm flood disaster risk assessment for southeast coastal area was got.The chart′s analytical result shows that highest risk areas are mainly distributed in Shanghai and most of the cities of Fujian Province,most parts of Zhejiang Province are higher risk areas and medium risk areas,the main areas of Guangdong province are medium risk areas,low risk areas and lower risk areas.The result is consistent with the actual situation of the areas.
