温带风暴潮灾害链的识别与区分--以莱州湾风暴潮为例

我国温带风暴潮灾害主要集中在渤海、黄海沿岸,其中莱州湾沿岸是频繁发生的重灾区。以识别莱州湾沿岸发生的温带风暴潮灾害链的组成为研究目标,通过2次典型灾害事件分析了温带风暴潮灾害的成因、发生及其演化规律等问题,进而识别了温带风暴潮灾害链发生过程中的灾害类别及相应致灾因子,根据致灾过程提出了5种灾害链条,最后区分了不同行业灾害损失中主要致灾因子的作用。研究结果可对温带风暴潮灾害链的预警及减灾工作提供决策支持。

The Identification and Differentiation of Temperate Storm Surge Disaster Chains-A Case Study on the Storm Surge in Laizhou Bay

Temperate storm surge disasters are mainly concentrated in the Bohai Sea and the Yellow Sea coast,of which the Laizhou Bay coast is a frequently-hit area.We take the identification of the composition of the disaster chain along the Laizhou Bay coast as the research goal,and analyze the causes and occurrence of disasters through typical disaster events and its evolutionary rules et al.and identify the disaster types and disaster-causing factors during the occurrence of the temperate storm surge disaster chain at last.According to the disaster-causing process,five disaster chains are proposed to distinguish the role of major disaster-causing factors in disaster losses in different industries.The research results can provide the decision support for the early forecast and mitigation of temperate storm surge disaster chains.
