风暴潮灾害经济损失评估分析——以山东省为例

Assessment and analysis of storm surge disaster economic losses——a case of Shandong Province

风暴潮灾害已成为目前致灾最严重的海洋灾害,合理评估风暴潮灾害经济损失是灾害管理的重要方面,对于防灾减灾及规划建设具有重要的研究意义。考虑到灾害系统的复杂性,间接经济损失往往难以统计,本文运用投入产出方法,采用山东省沿海受灾城市2003～2007的统计数据,对风暴潮灾害造成的间接损失进行科学评估,在此基础上测算了历年受灾城市的总损失,并制定出山东省风暴潮灾害综合损失分布的区划图。评估结果按综合损失程度排序依次是:威海、烟台、青岛、潍坊、东营、滨州、日照。

The storm surge disaster has become the most serious marine disasters now. Reasonable assessment of the economic loss caused by storm surge is an important aspect of disaster management, and it also has important research significance to disaster prevention, mitigation and constructive planning. Considering the complexity of disaster system, indirect economic losses are often difficult to evaluate. This paper applied input and output method, based on statistical data from 2003 to 2007 of Shandong province, made scientific assessment of indirect losses caused by storm surge, and then drew up zoning map of the distribution of comprehensive losses of Shandong Province. The results sorted by comprehensive losses in order are： Weihai, Yantai, Qingdao, Weifang, Dongying, Binzhou, Rizhao.
