| 摘 要： | 2014年4~9月对秦皇岛海域进行了调查,共鉴定出浮游植物3门33属70种,以硅藻门为主,7、8月份浮游植物种类数最多,约40种。在整个调查期间,浮游植物丰度在不同站位和月份之间差异较大,平均值为2.42×108个/m3,浮游植物优势种有北方娄氏藻、尖刺拟菱形藻、丹麦细柱藻、微小原甲藻等,优势种种类数9月最多,6月最少。浮游植物多样性指数为1.27~3.6,均匀度为0.31~0.73,6月份群落结构较单一,其他月份群落结构较稳定。

Characteristics of the phytoplankton community structure in the Qinhuangdao coastal area |
| |
| Abstract: | The community structure of phytoplankton in the Qinhuangdao coastal area was assessed from April to September, 2014. In total, 3 phyla, 33 genera, and 70 species of phytoplankton were identified. Bacillariophyta contained the largest number of species. July and August had more species than any other month. The average level of phytoplankton during the investigation was 2.42 × 108 cells·m-3, which varied significantly between different stations and months. The dominant species were Lauderia borealis, Nitzschia pungens, Leptocylindrus danicus, and Prorocentrum minimum, etc. The number of dominant species was the highest in September and the lowest in June. The diversity index ranged from 1.27 to 3.60, and the evenness ranged from 0.31 to 0.73. The community structure was stable in all months except June. |
