摘　　要：为确定长山列岛邻近海域褐牙鲆(Paralichthys olivaceus)增殖放流的合理容量,本文基于2016-2017年长山列岛邻近海域渔业资源与生态环境季度调查数据,构建了包括29个功能组的长山列岛邻近海域生态系统Ecopath模型,分析了该海域生态系统的能量流动特征,评估了放流种褐牙鲆的生态容量。研究表明:长山列岛邻近海域生态系统的营养级范围为1~4.57,总能量转换效率为6.23%,总初级生产量/总呼吸(TPP/TR)为1.47,总初级生产量/总生物量(TPP/TB)为26.87,循环指数(FCI)为6.91%,连接指数(CI)为0.24。长山列岛邻近海域褐牙鲆增殖生态容量为0.0143 t·km^(-2),约为该海域褐牙鲆当前生物量的1.55倍。褐牙鲆生物量达到生态容量时,长山列岛邻近海域生态系统的能量转换效率略有增加,总消耗量、总输出量等其他参数基本不受影响。Ecological carrying capacity of enhanced species is fundamental to the implementation of stock enhancement.In order to provide a reference for determining the reasonable release number of Paralichthys olivaceus enhancement in the adjacent waters of Changshan Islands,an Ecopath model consisted of 29 functional groups of the Changshan Islands ecosystem was developed based on the data of the fishery resources and ecological environment in the adjacent waters of Changshan Islands collected in 2016 and 2017.The overall energy flow characteristics of the ecosystem were examined,and the ecological carrying capacity of P.olivaceus in stock enhancement was assessed using the Ecopath model.The results showed that the trophic levels of functional groups varied between 1.00 and 4.57 in the adjacent waters of Changshan Islands ecosystem.The total energy conversion efficiency was 6.23%.The total primary production/total respiration(TPP/TR)was 1.47,and total primary production/total biomass(TPP/TB)was 26.87.Finn’s cycling index was low(FCI=6.91%)and system connectance index was low(CI=0.24).In the adjacent waters of Changshan Islands ecosystem,the ecological carrying capacity of P.olivaceus was 0.0143 t·km^(-2),which was 1.55 times the current biomass of P.olivaceus.The total energy conversion efficiency increased a little when the biomass of P.olivaceus reached the ecological capacity,which did not have impact on total consumption,total export and other parameters in the adjacent waters of Changshan Islands ecosystem.
