为研究獐子岛近岸人工鱼礁区浮游动物群落结构特征，利用2014年6月、10月和2015年6月、10月獐子岛近岸人工鱼礁区4个航次的调查资料，对该礁区浮游动物的物种种类、密度、生物量、多样性指数、与环境因子的关系等方面进行分析。调查结果表明，共发现29种浮游动物（包括6类浮游幼虫），2014年6月16种，2014年10月12种，2015年6月28种，2015年10月24种；优势种9种（包括浮游幼虫4种），拟长腹剑水蚤、中华哲水蚤、桡足类六肢幼体为4个航次共同优势种；浮游动物生物量和密度分布情况基本一致，最高值出现在2015年6月份的站位2，节肢动物门生物量和密度占绝对优势；聚类分析中2014年6月、10月和2015年6月浮游动物群落均分为4个聚类组，2015年10月分为3个聚类组；水温和盐度是影响浮游动物群落关系十分重要的环境因子，与浮游动物密度和生物量呈显著相关关系。%T he zooplankton species composition ,dominant species ,biomass ,abundance distribution ,and species di‐versity were studied in artificial reef area of Zhangzi Island in Dalian based on the data surveyed in June and Octorb‐er of 2014 and 2015 .The results showed that 29 zooplankton species were identified during the survey ,most being offshore lower‐salinity group ,wide temperature salinity group and offshore lower‐temperature group .In total ,16 species w ere observed in June of 2014 ,12 species in October of 2014 ,28 species in June of 2015 ,and 24 species in October of 2015 .There were 9 dominant species ,almost the Arthropod ,and the main dominant species were Cala‐nus sinicus ,Copepodite larvae ,and Oithona similes .The distribution of biomass and abundance of zooplankton were consistent basically ,and correlated with both water temperature and salinity .Community cluster analysis in‐dicated that in October and June of 2014 and in June of 2015 ,the zooplankton was divided into 4 cluster groups , and 3 cluster groups in October of 2015 .
