| 摘要: |
| 本研究基于2017年秋季在渤海湾海域以浅水Ⅰ型浮游生物网采集的浮游动物样品,分析了浮游动物的种类组成、丰度分布和生物多样性;通过结合现场获取的环境参数,探讨了环境因子与浮游动物群落特征之间的关系。结果如下:秋季浮游动物调查共鉴定各类浮游动物22种、浮游幼虫6类,合计种类数为28。桡足类为最为优势的类群,其在浮游动物的物种丰富度中占46.4%。渤海湾秋季浮游动物的优势种类共5个,包括中华哲水蚤、小拟哲水蚤、真刺唇角水蚤、近缘大眼水蚤和强壮箭虫。秋季浮游动物平均丰度为86.9 ind./m3,平均湿重生物量为640.7 mg/m3,香农-威纳指数和物种丰富度指数分别为1.87和1.08。浮游动物丰度与环境因子间的相关性分析表明,秋季影响渤海湾海域浮游动物分布的主要环境因子组合为盐度、叶绿素和浊度。与同期历史数据相比,浮游动物的丰度和生物量均有所下降。 |

| Abstract: |
| In this study, we analyzed the composition, abundance, and biodiversity of zooplankton based on the samples collected in Bohai Bay during the autumn of the year 2017. The abundance and determining factors were explored with multivariate analysis according to the sampling date and environmental parameters. A total of 28 zooplankton species/taxa (including 6 pelagic larvae) were identified in this survey. Copepods were the most abundant species. The numbers of pelagic copepod accounted for 46.4% of the total species richness. Calanus sinicus, Paracalanus parvus, Labidocera euchaeta, Corycaeus affinis, and Sagitta crassa were observed to be the dominant species. Based on the data collected during the autumn season, the average abundance, average biomass, Shannon-Wiener index (H′), and Margalef's index (D) were calculated at 86.9 ind/m3, 640.7 mg/m3, 1.87, and 1.08, respectively. The abundance along with biomass fluctuated and showed distinct heterogeneity in the Bohai Bay. The correlation analysis demonstrated that the distribution of zooplankton was affected by salinity, chlorophyll a concentration, and turbidity. The abundance and biomass of zooplankton declined in comparison to the data collected in 1991, 2002, and 2007. This research provided fundamental information on the long-term observation of zooplankton ecology in Bohai Bay. |
