风暴潮灾害经济损失灾前预评估研究进展

Research Progress on Pre-assessment of Economic Losses before Storm Surge Disasters

从灾害损失构成、灾害损失分离、损失评估方法、损失结果检验四个方面着手,指出灾害经济损失评估中存在的问题,并总结出灾害经济损失评估的研究方法,分析各个方法的优缺点以及存在的问题。总体来看,目前关于风暴潮灾害经济损失估算还存在一定的缺陷。随着沿海地区经济发展迅速,以及气旋活动的增强,精准的估算风暴潮灾害经济损失显得尤为重要。从灾害理论出发,建立科学合理的风暴潮灾害损失评估模型,是目前研究的重点议题,对于人民的生命财产安全和防灾减灾工作的实施都有重大的意义。

From the four aspects of disaster loss composition,disaster loss separation,loss assessment method,loss result test,we point out the problems existing in disaster economic loss assessment,summarize the research methods of disaster economic loss assessment,and analyze the advantages and disadvantages of each method and the existing problems.Generally speaking,there are still some defects in estimating the economic losses of storm surge disasters.With the rapid economic development in coastal areas and the enhancement of cyclone activity,it is particularly important to accurately estimate the economic losses caused by storm surge disasters.Based on disaster theory,the establishment of a scientific and reasonable storm surge disaster loss assessment model is the focus of current research,which is of great significance to the safety of people s lives and property and the implementation of disaster prevention and mitigation.
