风暴潮是海岸带最严重的灾害之一,区域风暴潮经济损失评估对区域产业经济布局、区域风暴潮减灾防灾具有重要意义。文章对江苏海岸带风暴潮承载体的损失率进行了研究,并与其他区域进行了对比分析。在研究中鲜明地提出了风暴潮区域生态环境经济损失评估的概念,利用综合指数法结合感知器法对海岸带风暴潮经济评估和风暴潮灾度进行了探讨,并以江苏盐城海岸带为例进行了实例研究取得了较好的效果。研究发现,CIISSEL值能较好地反映风暴潮的区域经济损失状况,D值的大小可以细化灾度的级别。当前,风暴潮的经济损失估值难点在于受灾体损失率的确定,通过试验的方式是解决这个问题的办法之一。
The storm surge is one of the most serious disasters on the coast. The economic loss assessment of regional storm surge is of great significance to regional industrial economic layout and regional storm surge disaster prevention and control. The paper studies the loss rate of storm surge bearing body in Jiangsu Coastal Zone and compares it with other regions. In the study, the concept of economic loss assessment of ecological environment in storm surge area is clearly put forward. The economic assessment of storm surge in coastal zone and the storm surge degree are discussed by means of integrated index method and perceptual method. Taking Yancheng Coastal Zone in Jiangsu as an example A case study has achieved good results. The study finds that the CIISSEL value can better reflect the regional economic loss caused by storm surges, and the value of D can refine the level of disaster. At present, the difficulty in the economic valuation of storm surges lies in the determination of the rate of disaster loss. The way of experiment is one way to solve this problem.
