中国沿海地区台风致灾因子危险性评估

从台风大风、暴雨和风暴潮3个方面选取指标,尝试构建了台风致灾因子危险性评价指标体系和评价模型.并在GIS环境下对沿海地区台风致灾因子危险性进行分析评价.评价结果显示:海南省和广东省、福建省、浙江省的沿海区域台风致灾因子危险性较大,上海市和广西省、江苏省的沿海区域以及广东省、福建省、浙江省的内陆地区台风致灾因子危险性中等...

Risk assessment of typhoon hazard factors in China coastal areas

Three indexes were chosen to establish a hazard assessment index system and model from wind, rain and storm surges . Then in a GIS environment, the risk of typhoon hazard factors were assessed. The assessment result showed that the risk of typhoon hazard factors is higher in Hainan province and the coastal areas of Guangdong, Fujian, Zhejiang provinces; Shanghai and the coastal areas of Guangxi, Jiangsu provinces have medium risk of typhoon hazard factors together with the inland areas of Guangdong, Fujian, Zhejiang provinces; while in Beijing, Tianjin, Liaoning, Hebei, Shandong provinces and the inland areas of Guangxi, Jiangsu provinces, the risk is lower. The result is valuable to provide reference for China coastal areas to deal with disasters.
