| Abstract: |
| Phytoplanktonic ecological provinces of the Yellow Sea (31.20°-39.23°N, 121.00°-125.16°E) is derived in terms of species composition and hydrological factors (temperature and salinity). 173 samples were collected from 40 stations from April 28 to May 18, 2014, and a total of 185 phytoplanktonic algal species belonging to 81 genera of 7 phyla were identified by Utermöhl method. Phytoplankton abundance in surface waters is concentrated in the west coast of Korean Peninsula and Korea Bay, and communities in those areas are mainly composed of diatoms and cyanobacteria with dominant species ofCylindrotheca closterium, Synechocystis pevalekii, Chroomonas acuta, Paralia sulcata, Thalassiosira pacifica and Karenia mikimotoi, etc. The first ten dominant species of the investigation area are analyzed by multidimensional scaling (MDS) and cluster analysis, then the Yellow Sea is divided into five provinces from Province I (P-I) to Province V (P-V). P-I includes the coastal areas near southern Liaodong Peninsula, with phytoplankton abundance of 35 420×103-36 163×103 cells/L and an average of 35 791×103 cells/L, and 99.84% of biomass is contributed by cyanobacteria. P-Ⅱ is from Shandong Peninsula to Subei coastal area. Phytoplankton abundance is in a range of 2×103-48×103 cells/L with an average of 24×103 cells/L, and 63.69% of biomass is contributed by diatoms. P-Ⅲ represents the Changjiang (Yangtze River) Diluted Water. Phytoplankton abundance is 10×103-37×103 cells/L with an average of 24×103 cells/L, and 73.14% of biomass is contributed by diatoms. P-IV represents the area affected by the Yellow Sea Warm Current. Phytoplankton abundance ranges from 6×103 to 82×103 cells/L with an average of 28×103 cells/L, and 64.17% of biomass is contributed by diatoms. P-V represents the cold water mass of northern Yellow Sea. Phytoplankton abundance is in a range of 41×103-8 912×103 cells/L with an average of 1 763×103 cells/L, and 89.96% of biomass is contributed by diatoms. Overall, structures of phytoplankton community in spring are quite heterogeneous in different provinces. Canonical correspondence analysis (CCA) result illustrates the relationship between dominant species and environmental factors, and demonstrates that the main environmental factors that affect phytoplankton distribution are nitrate, temperature and salinity. |

| 本研究通过对浮游植物物种组成和水文要素（温度和盐度）的分析对黄海(31.20°-39.23°N,121.00°-125.16°E)进行了生态分区。航次于2014年4月28日～5月18日在调查海区对40个站位进行了浮游植物样品采集，采用Utermöhl方法对样品进行了浮游植物种类鉴定分析，共计173个样品，鉴定得到7门81属188种浮游植物。表层浮游植物细胞丰度峰值集中在朝鲜半岛西侧和辽南-西朝鲜湾沿岸区域，高值区主要由硅藻和蓝藻共同刻画，主要优势物种为新月柱鞘藻（Cylindrotheca closterium）、派氏集胞藻（Synechocustis pevalekii）、尖尾蓝隐藻（Chroomonas acuta）、具槽帕拉藻（Paralia sulcata）、太平洋海链藻（Thalassiosira pacifica）和米氏凯伦藻（Karenia mikimotoi）等。对前十种优势种进行了多维度分析（MDS）和结聚类分析，并结合调查海区的水文要素将黄海分为5个生态区（P-1～P-5）。P-I区代表北黄海辽南沿岸，浮游植物细胞丰度介于35419×103～36162×103 cells/L，平均为35 791×103 cells/L，其中占总浮游植物生物量99.84%的是蓝藻；P-Ⅱ区代表黄海西海岸近岸，浮游植物总细胞丰度介于2×103～48×103 cells/L，平均为24×103 cells/L，占总浮游植物生物量63.69%的是硅藻；P-Ⅲ区代表长江冲淡水水域，浮游植物总细胞丰度介于10×103～37×103cells/L，平均为23×103cells/L，其中占总浮游植物生物量73.14%的是硅藻；P-IV区代表受黄海暖流影响区域，浮游植物总细胞丰度介于5×103～82×103 cells/L，平均为27×103 cells/L，其中占总浮游植物生物量64.17%的是硅藻；P-V区代表北黄海的冷水团水域，浮游植物总细胞丰度介于41×103～8 912×103 cells/L，平均为1763×103 cells/L，其中占总浮游植物生物量89.96%的是硅藻。综上，黄海春季浮游植物群落结构在各生态区间差异明显。通过对黄海春季浮游植物优势种与环境要素间进行的典范对应分析（CCA）得到了影响浮游植物分布的主要环境因子依次是硝酸盐、温度和盐度。 |
