| 摘 要： | 基于2018年海州湾及邻近海域的渔业资源底拖网调查数据，运用Ecopath with Ecosim 6.5 (EwE)软件构建由26个功能群组成的海州湾及邻近海域生态系统Ecopath模型，对现阶段该生态系统的营养结构、营养相互关系和系统总特征等进行分析，旨在为实施基于生态系统的渔业管理提供理论依据。结果表明:海州湾及邻近海域生态系统各功能群的营养级范围为1.00～4.19，其中鱼类营养级范围较广，为3.22～4.19；浮游动物和其他软体动物受初级生产者和捕食者的双重作用，处于重要的营养位置；生态系统总体特征分析显示，该生态系统的总初级生产量与总呼吸量的比值为7.096，总初级生产量与总生物量的比值为56.866，系统的连接指数和系统杂食指数分别为0.429和0.204，说明该生态系统目前处于不成熟、不稳定的状态，容易受外界扰动的影响。本文通过对海州湾及邻近海域生态系统模型进行研究，解析了该海域营养结构和系统发育状况，将为海州湾渔业资源的可持续利用和科学管理提供理论依据。

| Abstract: | Based on the data obtained from bottom trawl investigation in the Haizhou Bay and adjacent waters in 2018, a mass-balance model for the Haizhou Bay ecosystem was constructed by Ecopath with Ecosim software, consisting of 26 functional groups. Using Ecopath model, we evaluated the trophic structure, trophic impact relationship and ecosystem characters of the Haizhou Bay to provide a theoretical basis for the implementation of ecosystem-based fisheries management. The result showed that in this ecosystem trophic levels of functional groups varied from 1.00 to 4.19, and the range of fish trophic level was wide, ranging from 3.22 to 4.19. Phytoplankton and molluscs were in important nutritional positions in the ecosystem facing with the pressure from both the primary producers and predators. The evaluation of the ecosystem structure and function showed that the total primary production/total respiration (TPP/TR) was 7.096, total primary production /total biomass (TPP/B) was 56.866, the connectance index (CI) and system omnivory index (SOI) were 0.429 and 0.204, indicating that the Haizhou Bay ecosystem was in an immature, unstable state and was susceptible to external disturbances. Through the study of the Haizhou Bay and its adjacent waters ecosystem model, we analyzed the nutrient structure and phylogenetic status of the sea area, which would provide a theoretical basis for the sustainable utilization and scientific management of fishery resources in the Haizhou Bay. |
