分析了台州市台风风暴潮灾害特征,根据台州市沿海区域的地理、水文、社会经济等特点,在台风风暴潮数值模型模拟基础上,实现了基于格网和GIS技术的台风风暴潮灾害风险评价。通过构建台风风暴潮灾害风险评价模型,对台州市区沿海地区的台风风暴潮灾害危险度、脆弱性和防灾减灾能力进行了分析,在GIS平台上进行淹没分析、叠置分析、以及格网拟合计算,最后绘制出了台州市台风风暴潮灾害高分辨率风险区划图,以期为我国风暴潮防灾减灾工作提供科学参考。 Based on the typhoon storm surge numerical model simulation, the typhoon storm surge disaster risk assessment based on grid and GIS is realized based on the characteristics of the typhoon storm surge in Taizhou city. . Through the construction of typhoon storm surge disaster risk assessment model, the typhoon storm surge disaster risk, vulnerability and disaster prevention and mitigation ability in the coastal area of ​​Taizhou are analyzed. Submergence analysis, overlay analysis and grid Finally, the high-resolution risk zonation map of typhoon storm surge in Taizhou is plotted to provide a scientific reference for the work of storm surge disaster prevention and mitigation in China.
