The characteristics of phytoplankton assemblages were analyzed by the Utermöhl method in the southern Yellow Sea in summer, 2008. A total of 113 species (including varieties and forms), belonging to 51 genera and 3 phyla, were identified. Diatom was the most dominant group. The dominant species included Eucampia zoodiacus, Leptocylindrus danicus, Chaetoceros affinis, Thalassionema nitzschioides, Skeletonema costatum, Paralia sulcata and Chaetoceros tortissimus, which were eurytopic and temperate species. The cell abundance of phytoplankton ranged from 0.04 to 620.08 cells·mL with an average of 27.52 cells·mL. Horizontally, the cell abundance showed a decreasing trend from the south to the north. In terms of vertical distribution, the values in surface and subsurface water layers were higher than those in bottom water layers. Results of correlation analysis showed that phytoplankton cell abundance was positively correlated with water temperature, ammonia and nitrite concentrations, and negatively correlated with salinity and silicate concentration.
于 2008 年夏季，运用 Utermöhl 方法分析了南黄海浮游植物组合的特征。共鉴定出 113 种（包括变种和形态），隶属于 51 属 3 门。硅藻是最主要的类群。优势种包括环沟藻、丹麦细柱藻、拟菱形藻、角毛藻、中肋骨条藻、布氏弯角藻和优美角毛藻，它们是广适性和温带种。浮游植物细胞丰度范围为 0.04 至 620.08 个细胞·毫升，平均值为 27.52 个细胞·毫升。水平方向上，细胞丰度从南到北呈递减趋势。在垂直分布方面，表层和次表层水层的数值高于底层水层。相关分析结果表明，浮游植物细胞丰度与水温、氨氮和亚硝酸盐浓度呈正相关，与盐度和硅酸盐浓度呈负相关。
