Analysis of typhoon disaster chain and risk management in northward typhoon effecting Hebei

摘要

Based on northward typhoon effecting Hebei data during 1949-2018, 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, Secondly, 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, typhoon-gale, typhoon-storm surge three disaster chains were Built. And according to different disaster chains, corresponding disaster reduction measures were proposed, provided technical and decision support for the effective management of typhoon disaster risks.
