Abstract

Based on northward typhoon effecting Hebei data during1949-2018,key areas were Defining . The climatic features and impacts of typhoons entering the key areas were discussed. The results show that most of northward typhoon effecting Hebei occurred from late July to early August.The northward typhoon entering III district affected Hebei with the highest frequency, and rainstorm, gale and storm surge were easy to happen, Second -ly, it was II, which was to cause coastal and sea winds, When entering I, the TaihangMountains in the south had severe flood disasters. Starting from the disaster system theory, combined with the disaster data, the disaster-preventing environment and the disaster-bearing body information, the typhoon-storm, typhoongale, typhoon-storm surge three disaster chains were Built. And accord -ing to different disaster chains, corresponding disaster reduction measures were proposed, provided technical and decision support for the effective management of typhoon disaster risks.

影响河北的北上台风灾害链分析及风险管理
根据1949-2018年北上台风对河北的影响资料,确定了重点区域。讨论了台风进入重点地区的气候特征及其影响。结果表明,影响河北的北上台风主要发生在7月下旬至8月上旬。北上台风进入III区对河北的影响频率最高,容易发生暴雨、大风和风暴潮;II区台风进入I区,引起沿海和海风,南部太行山洪水灾害严重。从灾害系统理论出发,结合灾害数据、防灾环境和承灾体信息,构建了台风-风暴、台风-风暴潮三条灾害链。并针对不同的灾害链,提出相应的减灾措施,为有效管理台风灾害风险提供技术和决策支持。关键词——台风向北,影响关键领域,灾害链、防灾摘要——利用1949 - 2018年影响河北的北上台风资料,划定影响河北的台风关键区,对进入关键区的北上台风的气候特征以及影响进行分析发现,影响河北的北上台风大多发生7月下旬8月上旬;北上台风进入III区影响河北的频率最高,暴雨,大的风,风暴潮均易发生;其次为II区,易引发沿海及海上大风;进入我区时,西部太行山暴雨山洪灾害严重。从灾害系统论出发,结合灾情资料、孕灾环境和承 灾体构建北上台风影响河北的台风—暴雨,台风— 大风、台风—风暴潮三种灾害链,并且针对灾害链 的不同,提出对应的断链减灾对策,为有效进行台 风灾害风险管理,提供技术支持和决策支撑。 关键词—北上台风,台风关键区,灾害链,减灾对
