浙江海域赤潮灾害直接非经济损失的估算

Estimation of Direct Non-economic Loss Caused by Red Tide Disaster in Maritime Space of Zhejiang

赤潮灾害造成的直接非经济损失评估包括对海域环境破坏与科研文化损失估算两大类共7部分。以2009年浙江海域赤潮灾害为例,利用影子工程法、替代花费法、成果参照法和条件价值法等评估方法进行估算,得到当年浙江海域赤潮灾害造成的直接非经济损失为316.57亿元,其中海域环境破坏损失占99.42%,以废弃物处理、初级生产和营养元素循环损失三大损失为主;赤潮灾害造成的直接非经济损失大于直接经济损失。同时认为对赤潮灾害造成的直接非经济损失评估存在偏差,应当进一步加以完善。

Estimation of direct non-economic loss caused by red tide disaster consists of seven parts which ould be divided into two broad categories：estimation of environmental disruption in maritime space and scientific cultural loss.Taking the red tide disaster in maritime space of Zhejiang in 2009 as an example,several ways such as Shadow Engineering Method,Replacement Cost Method,Results Reference method,and Contingent Value Method were estimated.The result showed,that the direct non-economic loss caused by red tide disaster in maritime space of Zhejiang that year was 316.51×108 yuan RMB,99.42% of which was environmental disruption in maritime space,mainly on three losses of waste proposal,basic-level production and;direct non-economic loss caused by red tide disaster was more serious than direct economic loss.Meanwhile it pointed that there was deviation in estimation of direct non-economic loss caused by red tide disaster,and it should be improved in future.
