摘要:
以2020年8-9月在青岛近岸海域进行的浮游动物调查数据为基础,分析了该海域浮游动物的群落结构特征。调查海域共发现浮游动物成体29种,浮游幼虫14类,其中浅水Ⅰ型网调查发现成体27种,浮游幼虫14类,浅水Ⅱ型网发现成体24种,浮游幼虫12类;浅水Ⅰ型网和浅水Ⅱ型网调查浮游动物平均丰度分别为128.4 ind/m3、1010.9 ind/m3;平均生物量(湿重)为37.7 mg/m3、101.3 mg/m3;平均多样性指数为2.18、2.11;平均丰富度指数为0.95、1.77;平均均匀度指数为0.54、0.70;浅水Ⅰ型网采集的浮游动物种类数量略多于浅水Ⅱ型网,但在丰度和生物量上,浅水Ⅱ型网的调查结果远大于浅水Ⅰ型网。在群落多样性评价指数方面,两种网具调查结果有一定的差异。

Abstract:
Based on the investigation data of zooplankton in the sea area near Qingdao in August and September 2020, the community structure characteristics of zooplankton was analysed. The results showed that 29 species and 14 taxa of zooplankton were found, including 27 species and 14 taxa in shallow water type I net, 24 species and 12 taxa in shallow water type Ⅱ net, the average abundance of zooplankton was 128.4 ind. /m3 in shallow water type I net and 1010.9 ind. /m3 in shallow water type Ⅱ net, the average biomass (wet weight) was 37.7 mg/m3, 101.3 mg/m3, the average Shannon-Wiener index (H'), Margalef's species richness diversity (D) and Pielou's evenness index (J) were 2.18, 0.95, 0.54 in shallow water type I net, respectively, and 2.11, 1.77, 0.70 in shallow water type Ⅱ net, respectively. In the number of zooplankton species collected, the number of species collected by shallow water type I net is slightly more than that of shallow water type II net, but in the abundance and biomass, the survey results of shallow water type II net are much greater than that of shallow type I net. In the community diversity evaluation index, there was some differences between the two type nets.
Key words:  Qingdao, zooplankton, community structure, diversity, dominant species
