Present study investigated composition and distribution of chromophytic phytoplankton in the Bohai Sea (BS) and the Yellow Sea (YS) by using rbcL genes. Bacillariophyceae, Haptophyceae and Pelagophyceae were the most abundant phytoplankton groups. Distinct phytoplankton communities were observed in the BS and the YS: offshore stations were dominated by bloom forming genera Thalassiosira and Skeletonema, while brown tide-forming species including Chrysochromulina spp. and Aureococcus anophagefferens were commonly found in the nearshore areas. Redundancy analysis showed that phosphate, temperature and silicic acid play key roles in structuring chromophytic phytoplankton, such as phytoplankton at nearshore stations were affected by nutrient runoff from adjacent rivers (Yellow River). Anthropogenic activities in the Bohai Sea and seasonal circulation of ocean currents may also contribute to shaping chromophytic phytoplankton communities. This study provides data support and foundational observations of chromophytic phytoplankton in the BS and the YS, and their responses to environmental gradients and human activities.
本研究通过使用 rbcL 基因调查了渤海（BS）和黄海（YS）中色素浮游植物的组成和分布。硅藻、甲藻和隐藻是最丰富的浮游植物群体。在 BS 和 YS 观察到了不同的浮游植物群落：近海站位以形成赤潮的属塔玛斯氏藻和中肋骨条藻为主，而近岸地区则常见棕潮形成种如金藻属和夜光藻。冗余分析表明，磷酸盐、温度和硅酸在色素浮游植物的结构中起着关键作用，例如，近岸站位的浮游植物受到来自附近河流（黄河）的营养径流的影响。渤海的人类活动和季节性海流循环也可能有助于塑造色素浮游植物群落。本研究为 BS 和 YS 中的色素浮游植物及其对环境梯度和人类活动的响应提供了数据支持和基础观测。
