| 摘要: |
| 2016年4～11月对烟台四十里湾近岸的3个扇贝养殖区浮游植物群落进行了8个航次的调查。调查共鉴定出浮游植物5门67属/种, 其中硅藻门占总种数的65.67%, 菱形藻属种类最多; 其次为甲藻门占13.43%, 角藻属种类最多; 此外还发现27属/种赤潮藻, 提示该海域需加强赤潮防范。Shannon-Winner指数、Margalef指数和均匀度指数分析显示, 该调查海域浮游植物多样性和物种丰富度总体较好, 群落结构较为稳定。 |

| Abstract: |
| Eight investigations of phytoplankton communities were conducted in three scallop culture areas near Sishili Bay in Yantai from April to November of 2016. A total of 5 phyla and 67 genera and species of phytoplankton were identified, among which Bacillariophyta accounted for 65.67% of the total species, and Nitzschia accounted for the maximum population, followed by Pyrrophyta, accounting for 13.43%, of which Ceratium comprised the maximum population. Furthermore, 27 genera and species of red tide algae were identified that needed to be prevented from the red tide. Based on the analyses of the Shannon–Wiener index, the Margalef index, and Pielou’s index, the investigated areas had good phytoplankton diversity and species richness and a stable community structure as well. |
