摘　　要：2008年8月中韩合作对南黄海生态系统进行了整体调查,调查站位共计37个。利用流式细胞仪测定了南黄海微微型浮游植物丰度,结合理化环境因子,分析了它们在夏季南黄海的分布特征。所测微微型真核浮游植物丰度平均值为1.9×103个/mL,最大值为2.4×104个/mL;聚球藻丰度平均值为5.3×104个/mL,最大值为5.1×105个/mL;从河口近岸到南黄海中部的宽阔海域,随着环境因子的变化,微微型浮游植物在各海区的分布明显不同,表现为河口近岸区域丰度大,离岸丰度小的特点;各站位丰度垂直分布主要趋势是上大下小,在跃层突出。根据分布趋势,聚球藻可分为两种垂直分布类型,微微型真核浮游植物分为三种。这些分布差异源于长江冲淡水和黄海冷水团的影响。The abundance and distribution characteristics of picophytoplankton in the southern Huanghai Sea were investigated by flow cytometry（FCM） during August 2008.The results show that the average abundance and maximum abundance of photosynthetic picoeukaryotes are 1.9×103 and 2.4×104 cells/mL respectively,while the average abundance and maximum abundance of Synechococcus are 5.3×104 and 5.1×105 cells/mL respectively.From coastal to central broad waters,the distribution of picophytoplankton varied significantly with the changes of environmental factors.The high abundance of picophytoplankton was observed in coastal and estuarine areas,and much lower abundance was recorded in the central broad waters.The relationships between the abundance of picophytoplankton and the environmental factors were also discussed.And the Huanghai Sea Cold Water Mass and the Changjiang diluted water were identified to be the major factors influencing the distribution of picophytoplankton in the study area.
