| 摘 要： | 为了解黄河口及邻近海域鱼卵、仔稚鱼的群落结构动态，分别于2014年、2015年、2017年和2018年的6月利用大型浮游生物网对黄河口及邻近海域进行4个航次的表层水平拖网调查。根据鱼卵、仔稚鱼的种类组成、数量分布等群落结构特征，运用生物多样性指数、聚类分析和皮尔逊相关性矩阵分析等方法对该海域鱼卵、仔稚鱼的资源分布进行了综合研究。结果表明，4年调查共采获鱼卵3 829粒，仔稚鱼234尾，隶属于7目14科15属。鱼卵的主要优势种为鳀（Engraulis japonicus）和短吻红舌鳎（Cynoglossus joyeri），仔稚鱼的主要优势种为斑鰶（Konosirus punctatus）和虾虎鱼科未定种Gobiidae sp.。生物多样性各指数均以2015年最高，2018年最低。利用R语言对鱼卵、仔稚鱼年间种类组成相似性进行聚类，将4个调查年份划分为3组，各分组之间主要的分歧种均为鳀。生物多样性各指数与环境因子之间皮尔逊相关性分析表明，盐度与鱼卵、仔稚鱼生物多样性的关系较为密切。分析认为，黄河口及邻近海域鱼卵、仔稚鱼群落分布和多样性的年间变化特征体现了鱼类对环境变异的响应。

| Abstract: | In order to understand the community structure dynamics of fish eggs and larvae in the estuarine waters, four surveys were conducted in the coastal waters of the Huanghe River Estuary in June of 2014, 2015, 2017, and 2018. According to the species composition and quantitative distribution of fish eggs and larvae, the resource distribution of fish eggs and larvae in this water area was comprehensively studied by using the methods of biodiversity index, R software clustering and Pearson correlation matrix analysis. The results showed that a total of 3 829 fish eggs and 234 larvae were collected during the four surveys by horizontal trawl with plankton net. The obtained fish eggs and larvae belonged to 7 orders, 14 families and 15 genera. The dominant species of eggs were Engraulis japonicus and Cynoglossus joyeri. The dominant species of larvae were Konosirus punctatus and Gobiidae sp. All biodiversity indexes were the highest in 2015 and the lowest in 2018. Used the R language to cluster the similarity of the species composition between fish eggs and larvae, and divided the 4 survey years into 3 groups, each grouping the main divergent species were E. japonicus. The results of Pearson correlation matrix showed that salinity was closely related to the biodiversity of fish eggs and larvae. The analysis showed that the annual variation characteristics of community distribution and diversity of fish eggs and larvae in the Huanghe River Estuary and adjacent waters reflected the response of fish to environmental variation. |
