摘要
风暴潮灾害成灾频率高、致灾强度大,是我国的主要海洋灾害之一。浙江省位于我国东部沿海,是我国人口分布以及社会经济发展的重要区域。本文采用脆弱性曲线法开展了适用于风暴潮灾害的受灾人口和直接经济损失定量评估方法研究。将研究成果应用于舟山市普陀区,在验证模型可靠性的基础上,开展了不同风暴潮重现期情景下的灾害损失定量评估。结果显示:受灾人口较多和直接经济损失较大的地区主要集中出现在舟山本岛的东南部区域,其中,工业仓储、住宅和交通用地更易受到风暴潮灾害的直接影响,损失值较大。定量评估结果可为进一步开展我国沿海地区风暴潮灾害损失评估提供数据基础支持,可有效地支撑沿海地区风暴潮灾害防灾减灾能力。
Storm surge disaster is one kind of meteorological disaster in China.It may cause serious destruction on coastal facilities.Zhejiang province is located in the eastern coastal area of China.It is an important area for the population distribution and development of economy and society.In this paper,we used Vulnerability curve model to research the methods of quantitative assessment of the affected population and direct economic loss.On the basis of verifying the reliability of the model,we test the different quantitative assessments of disaster loss based on different storm surge return period.We used the results in Putuo Zhoushan,and the result shows that the areas of southeast Zhoushan island have large affected population and direct economic loss.Among these areas,industrial storage,residence and traffic land are more especially directly influenced by the storm surge.The results of quantitative assessment can provide basic data support for the further development of storm surge caused loss quantitative assessment in coastal area of China,and efficiently improve the abilities of storm surge disaster prevention and reduction.
