| 摘要: |
| 为了解黄、渤海浮游动物群落特征, 利用2014年春季在黄、渤海采集的浮游动物样品, 对浮游动物的种类组成、丰度、生物量、优势种和生物多样性进行分析, 分析浮游动物群落结构与环境因子间的相关关系, 并划分了浮游动物群落。共记录浮游动物78个种类(南黄海69种、北黄海42种、渤海47种), 浮游幼虫占比最高。研究海域的浮游动物平均丰度为3 183.8±7 829.7 ind./m3, 剔除夜光虫(Noctiluca scintillans)后, 平均丰度为537.3±554.2 ind./m3; 平均生物量为409.1±517.5 mg/m3。夜光虫、中华哲水蚤(Calanus sinicus)和强壮箭虫(Sagitta crassa)是黄、渤海的共同优势种。结合香农-威纳指数和累积优势度曲线分析, 渤海浮游动物的生物多样性最低, 北黄海次之, 南黄海的多样性最高。聚类分析表明, 研究海域浮游动物群落可划分为渤-黄海沿岸群落、黄海中部群落和南黄海-东海近岸混合水群落。相关性分析显示, 研究海域与浮游动物群落结构相关性最高的环境因子组合为温度、盐度和叶绿素a浓度。 |

| Abstract: |
| Community characteristics of zooplankton in the Bohai Sea and Yellow Sea were investigated based on samples collected in April–May 2014. Species composition, abundance, dominant species, and zooplankton biodiversity were analyzed with the environmental data. A total of 78 zooplankton taxa were identified (69 in the South Yellow Sea, 42 in the North Yellow Sea, and 47 in the Bohai Sea). The average abundance of zooplankton in the studied sea area was 3 183.8±7 829.7 ind./m3, and the mean abundance (excluding Noctiluca scintillans) was 537.3±554.2 ind./m3. The mean biomass was 409.1±517.5 mg·m3. The most common dominant species found in the Yellow Sea and Bohai Sea were N. scintillans, Calanus sinicus, and Sagitta crassa. The highest biodiversity was detected in the South Yellow Sea, followed by the North Yellow Sea and Bohai Sea. Cluster analyses revealed three communities: the Bohai Sea-Yellow Sea Neritic Community, the Yellow Sea Central Community, and the Southern Yellow Sea–East China Sea Mixed Water Community. The results of the correlation analysis showed that the combination of temperature, salinity, and chlorophyll-a concentration had the strongest correlation with the zooplankton community structure in the study area. |
