| 摘要: |
| 渤海是我国最大的半封闭型内海，也是重要的海洋生物产卵场、育幼场和索饵场。其陆源径流丰富，环境异质性高，具有很高的浮游植物物种多样性，其中包括大量的赤潮物种。该海域赤潮频发对水产养殖、生态环境、旅游业等造成了很大影响。因此，针对该海域浮游植物物种多样性的研究具有极其重要的意义。本文整理了1957—2019年间46个主要航次的调查资料，比较分析了这些航次中鉴定的浮游植物组成以及相对丰度，并跟踪分析了近20年来渤海的主要赤潮事件，重点描述了赤潮物种多样性，并详细阐述了常见赤潮物种。在航次鉴定的140个赤潮物种中，包括硅藻78种，甲藻52种，定鞭藻5种，绿藻4种和蓝藻1种。本文为比较研究包括渤海海域在内的不同海域浮游植物和赤潮物种的多样性，探索海洋生物多样性的起源和演化规律，解读宏基因组学及宏条形码分析结果提供了基础和参考。 |

| Abstract: |
| The Bohai Sea is the largest semi-closed inland sea in China. It is an important spawning, nursery, and feeding ground for marine organisms. It features rich runoffs from land sources, high environmental heterogeneity, and high phytoplankton species diversity. Among them, there are a large number of red tide species, which promote frequent occurrence of blooms and have a large negative impact on aquaculture, ecological environment, and tourism. It is therefore of great significance to study phytoplankton and red tide species in this area. In this review, we examined and compared the composition and relative abundance of phytoplankton reported from the marine surveys carried out between 1957 and 2019 in the Bohai Sea, with a focus on the red tide species. We also analyzed and reviewed major red tide events in Bohai Sea in the past 20 years. Altogether 140 species were identified as red tide species in the Bohai Sea in all marine surveys, which included 78 species in Ochrophyta, 52 species in Dinoflagellata, 5 species in Haptophyta, 4 species in Chlorophyta, and 1 species in Cyanophyta. We also provided detailed descriptions of common red tide species in the Bohai Sea. This review provides a reference for studying biodiversity of phytoplankton and red tide species in the Bohai Sea as well as in other sea areas, and for facilitating the interpretation of metagenomics and macrobarcoding results. |
