| 摘要: |
| 东海海域是我国典型的赤潮频发区，东海沿海的水产养殖业和生态系统等都受到很大影响。本文分析了1958—2019年间东海海域内67个浮游植物调查数据，通过比较东海海域浮游植物物种调查获得的历史数据，重点分析赤潮及赤潮物种的组成，并对相关数据进行剖析和解读。共统计出东海海域浮游植物773种（包括65个变种），其中棕鞭藻门470种（包含42个变种），甲藻门253种（包含23个变种）。这些浮游植物中包括了赤潮物种135个，其中棕鞭藻门73个物种，甲藻门56个物种，定鞭藻门和蓝藻门各3个物种。比较发现该海域硅藻和甲藻的相对物种丰富度并没有发生显著的变化。本文分析结果可为东海海域和其他海域浮游植物和赤潮物种生物多样性的研究提供参考。 |

| Abstract: |
| The East China Sea (ECS) is known for frequent harmful algal blooms (HABs), which have affected the ecosystem and local aquaculture industry. In this review, we examined and compared the composition of phytoplankton sampled in 67 reported expeditions from 1957 to 2019 in the ECS. In total, 773 species (65 varietas) were identified, including 470 Ochrophyta species (42 varietas) and 253 Dinoflagellata species (23 varietas). Of the 773 phytoplankton species described in these expeditions, 135 red tide species were identified, including 73 Ochrophyta species, 56 Dinoflagellata species, 3 Haptophyta species, and 3 Cyanophyta species. No obvious trend of variation was shown in the relative proportion of diatoms and dinoflagellates in the ECS in recent years. Based on the dada collection of phytoplankton species in the past in the ECS, this review focuses on analyzing the composition and diversity of red tide and red tide species. This review can provide a reference for interpreting results future studies on biodiversity of phytoplankton and red tides in the ECS and other regions. |
