| 摘要: |
| 文章于2018年8月、10月和2019年2月、5月对庙岛群岛海域59个站位进行4个航次的水质及浮游动物调查，统计分析I型网采集浮游动物的群落结构、时空分布及与各环境因子的相关性。结果表明：庙岛群岛海域共鉴定出浮游动物93种，分属13大类，其中桡足类和浮游幼虫均为25种，共占比53.8%。各季节出现的优势种有一定差异，中华哲水蚤在四季当中均为优势种。全年大型浮游动物的丰度在3.0~2 720 ind/m3之间波动，平均值为122.41 ind/m3；生物量在0.25~3 106.75 mg/m3之间波动，平均值为172.15 mg/m3；多样性指数介于0.058~3.670之间，平均值为1.431；均匀度指数介于0.030~0.922之间，平均值为0.467；丰富度指数介于0.362~7.964之间，平均值为2.358。Pearson相关性分析及典范对应分析(CCA)结果显示，各环境因子中温度与盐度对浮游动物的分布影响尤为显著。 |

| Abstract: |
| Based on 4 cruises in August and October 2018, February and May 2019,water quality and zooplankton at 59 stations in Miaodao Archipelago were investigated. The community structure, spatial and temporal distribution of zooplankton collected by type I net and the correlation with various environmental factors were analyzed statistically. The results showed that: a total of 93 species of zooplankton were identified in Miaodao Archipelago, including 13 categories, the species of copepods and planktonic larvae were 25 respectively, accounting for 53.8% in total. The dominant species in different seasons were different, and Calanus sinicus was dominant in all seasons. The abundance of zooplankton ranged from 3.0 to 2 720 ind/m3, with an average of 122.41 ind/m3, and the biomass ranged from 0.25 to 3 106.75 mg/m3, with an average of 172.15 mg/m3. The Shannon-Wiener index varied from 0.058 to 3.670, with an average of 1.431, the Pielou evenness index varied from 0.030 to 0.922, with an average of 0.467, and the Margalef index varied from 0.362 to 7.964, with an average of 2.358. The results of Pearson correlation analysis and canonical correspondence analysis showed that the distribution of zooplankton was influenced by various environmental factors, among which temperature and salinity were the most important factors. |
