中文摘要：

【目的】以曹妃甸某污水排海工程为例,对排海工程渔业资源损害定量分析方法进行探讨,为今后类似工程生物资源损害评估提供参考依据.【方法】在大量已有研究成果及经验的基础上,对水污染生物资源损害计算基本公式、受损范围及死亡率的确定方法进行讨论.结合工程实际情况及海洋生态环境现状调查结果,定量分析工程对渔业资源造成的损害.【结果】工程对海洋渔业资源造成损害的面积约为0.218km2,在此范围内,仔鱼和鱼卵的损失量分别约为4.65×10^6尾和9.63×10^6个,而成鱼基本不受影响.【结论】本方法的提出对今后海洋工程生物资源损害研究具有一定的参考价值.

英文摘要：

Objective]Taking sewage marine disposal engineering in Caofeidian as example,the quantitative analysis method of the fishery resources damage was discussed,to provide some reference for similar proj ects.[Methods]Based on a large number of researching results and engineer experiences,the estimation formula of biological resource damaged,and the determi-nation method of influence area and mortality rate of organisms were discussed.Combined with the actual situation of engineering and the present situation of ecological environment, the fishery resources damage caused by engineering was analyzed.[Results]The engineering affects on the area of marine fishery resources is about 0.218km2 .In this region,the loss quantity of the larvae and roes of some fish roughly is 4.65×106(ind)and 9.63×106(ind) respectively,and adult fish is unaffected.[Conclusion]The method proposed in this paper provides reference for research on the biological resource damage of marine engineering.
