液化天然气接收站取排水对渔业资源的影响研究——以温州LNG接收站工程为例

液化天然气接收站取排水过程的卷载效应、冷冲击效应和余氯效应均会对渔业资源造成一定影响。文章以温州LNG接收站工程为例，根据2017年11月在工程附近海域的渔业资源现状调查资料，定性分析了取排水对渔业资源的影响，并对卷载效应和余氯排放造成的渔业资源损失进行定量估算。温州LNG接收站工程建成投产近期运行期间，将造成鱼卵损失量为1.45×107 ind./a，仔鱼损失量为1.66×107ind./a，鱼类幼体损失量为7.56×104 ind./a，虾类幼体损失量为8.68×104 ind./a，蟹类幼体损失量为0.04×103 ind./a。

Impact of Water Intake and Discharge from Liquefied Nitrogen Gas Receiving Stations on Fishery Resources:A Case Study of the Wenzhou Liquefied Nitrogen Gas Receiving Station

Water intake and discharge from liquefied nitrogen gas (LNG) receiving stations generates entrainment effects,cold shock,and residual chlorine,which have significant impacts on fishery resources.In this study,the Wenzhou LNG receiving station and the sea near the facility were selected for a case study.Utilizing survey data regarding the status of fishery resources in November 2017,the impact of water intake and discharge by the receiving station on the resources was qualitatively analyzed,and losses caused by the entrainment effect and residual chlorine discharge were quantitatively estimated.During the construction of the receiving station and the commencement of its operations,the loss of fish eggs,larvae and juveniles amounted to 1.45×107,1.66×107,and 7.56×104 ind.·a-1,respectively,and the loss of shrimp and crab juveniles was 8.68×104 and 0.04×103 ind.·a-1,respectively.
