| 摘 要： | 以2015年5月(春季)和10月(秋季)在日照岚山港北作业区邻近海域进行的浮游动物调查数据为例，分析了该海域浮游动物的群落结构特征。调查海域两季共发现浮游动物成体20种，浮游幼虫7类，其中春季成体12种，浮游幼虫4类，秋季成体19种，浮游幼虫6类；春、秋两季调查浮游动物平均丰度分别为128.1 ind./m3、103.3 ind./m3；平均生物量(湿重)分别为1 129.9 mg/m3、954.3 mg/m3；平均多样性指数分别为2.39、2.01；平均丰富度指数分别为0.85、1.21；平均均匀度指数分别为0.87、0.62；春季调查优势种为强壮箭虫(Sagitta crassa)、中华哲水蚤(Calanus sinicus)、真刺唇角水蚤(Labibocera euchaeta)、太平洋纺锤水蚤(Acartia pacifica)、球型侧腕水母(Pleurobrachia globosa)，秋季调查优势种为太平洋纺锤水蚤、小齿海樽(Doliolum denticulatum)、强壮箭虫、真刺唇角水蚤；聚类分析表明，调查海域浮游动物可划分为3个群落。本研究可为深入研究该海域浮游动物群落结构提供重要的基础数据。

| Abstract: | Based on the investigation data of zooplankton in the sea area near the north operation area in the Lanshan Port of Rizhao Port in May (spring) and October (autumn) 2015, the community structure characteristics of zooplankton was analysed in this paper. The results showed that 20 species and 7 taxa of zooplankton were found in the two seasons, including 12 species and 4 taxa in spring and 19 species and 6 taxa in autumn, the average abundance of zooplankton were 128.1 ind./m3 in spring and 103.3 ind./m3 in autumn, the average biomass (wet weight) were 1 129.9 mg/m3 and 954.3 mg/m3, the average Shannon-Wiener diversity index (H'), Margalef’s species richness diversity (D) and Pielou’s evenness index (J) were 2.39, 0.85, 0.87 in spring, respectively, and 2.01, 1.21, 0.62 in autumn, respectively. In spring, the dominant species were Sagitta crassa, Calanus sinicus, Labibocera euchaeta, Acartia pacifica, Pleurobrachia globosa, while in autumn, the dominant species were Acartia pacifica, Doliolum denticulatum, Sagitta crassa, Labibocera euchaeta. Cluster analysis showed that the zooplankton in the investigation area could be divided into three groups. This study could provide important basic data for further study of zooplankton community structure in the coastal waters of Rizhao. |
