摘　　要：调查水生生物资源现状是科学制定水产种质资源保护区管理策略的重要依据。为了掌握庐山西海鳡国家级水产种质资源保护区内水生生物资源现状,于2019年10月对庐山西海全湖浮游植物资源、浮游动物资源和鱼类种类组成进行了初步调查。结果显示,庐山西海有浮游植物123种,平均密度、平均生物量和香农威纳多样性指数分别为27.13×10^(6)ind./L、1.75mg/L和1.579;浮游动物56种,平均密度、平均生物量和香农威纳多样性指数分别为326.6 ind./L、1.13 mg/L和1.686;鱼类22种,其中鲤形目最多为16种,鲈形目4种,鲇形目2种。与历史资料相比,庐山西海的鱼类种类数量以及浮游植物和浮游动物的生物量都出现了一定程度的下降。为了更好地保护庐山西海宝贵的水生生物资源,建议采取优化保护区功能区划、提升管理能力建设和加强保护宣传等对策。Information on aquatic biological resources is of great significance for the management of aquatic germplasm reserves.In order to understand the current situation of aquatic organism resources of Elopichthys bambusa national aquatic germplasm reserves of the Lushanxihai Lake,the fish species compostion and the resources of phytoplankton and zooplankton were investigated in October 2019.A total of 123 species of phytoplankton were sampled,the average density was 27.13×10^(6) ind./L,the average biomass was 1.75 mg/L,and the Shannon Weiner diversity index was 1.579.A total of 56 species of zooplankton were sampled,the average density was 326.6 ind./L,the average biomass was 1.13 mg/L,and the Shannon Weiner diversity index was 1.686.A total of 22 fish species were sampled,and 16 species b-long to the order Cypriniformes,4 species belong to the order Perciformes,2 species belong to the order Siluriformes.Compared with the historical data,the number of fish species and the biomass of phytoplankton and zooplankton in the Lushanxihai Lake were all declined to a certain extent.In order to protect the precious aquatic organism resources in the Lushanxihai Lake more effectively,we suggest to optimize the functional zoning of the reserves,improve management capacity and strengthen protection publicity.
