| 摘要: |
| 长江口海域是我国的一个典型水域，具有很高的浮游植物物种多样性，其中包括很多种赤潮物种，引起赤潮频发。本文总结了过去40年间长江口海域历次航次调查的研究结果，比较分析了52个航次调查鉴定的浮游植物组成，重点探索了赤潮物种的组成，并详细描述了长江口海域的6种典型赤潮物种：中肋骨条藻、东海原甲藻、旋链角毛藻、夜光藻、米氏凯伦藻和尖刺拟菱形藻。在文献报道的657个浮游植物物种（包括571个物种和86个鉴定到属的未定种）中，硅藻（368个物种和55个未定种）和甲藻（149个物种和15未定种）占绝大多数。这些浮游植物中赤潮物种占125个，包括硅藻69种、甲藻49种、金藻2种、隐藻1种和蓝藻3种。本文为比较研究不同海域赤潮物种的生物多样性，探讨生物多样性的起源与演化，为解读宏基因组学及宏条形码分析结果提供了基础。 |

| Abstract: |
| The Changjiang (Yangtze) River estuary is a special marine region in China. It has a high phytoplankton diversity, including a variety of red tide species, with frequent red-tide outbreaks in recent years. In this review, the compositions of phytoplankton identified in 52 reported expeditions in the Changjiang Estuary were examined and compared, with a focus on red tide species. Of the 657 phytoplankton described in these expeditions (including 571 species and 86 unidentified species), diatoms (368 species and 55 unidentified species), and dinoflagellates (149 species and 15 unidentified species) were the dominant phyla. Among these phytoplankton, 125 species were identified as red tide species in the Changjiang Estuary, including 69 diatoms, 49 dinoflagellates, 2 chrysophytes, 3 cyanobacteria, and 1 cryptophyta. The frequently-seen red-species in the estuary included Skeletonema costatum, Prorocentrum donghaiense, Chaetoceros curvisetus, Noctiluca scintillans, Karenia mikimotoi, and Pseudo-nitzschia pungens. This review shall provide a reference for studying biodiversity of phytoplankton and HAB (harmful algae bloom) species in different sea areas, discussing the origin and evolution of biodiversity, and facilitating the interpretation of metagenomics and macrobarcoding results. |
