应用Uterm?hl方法对2012年秋季渤海和北黄海浮游植物的物种组成、细胞丰度和群落结构特征等进行了分析，并应用典范对应分析(CCA)对调查海域浮游植物和环境因子进行了相关性分析．本次调查共鉴定出浮游植物3门38属94种，其中硅藻门29属62种，甲藻门8属31种，金藻门1属1种，物种生态习性以温带种和广布种为主．调查海域浮游植物细胞丰度介于0.30×103～10.48×103 L-1，平均值为2.79×103 L-1，硅藻主要优势物种为具槽帕拉藻(Paralia sulcata)和圆筛藻(Coscinodiscus sp.)；甲藻主要优势种为梭状角藻(Ceratium fusus)和三角角藻(Ceratium tripos)．浮游植物群落 Shannon-Wiener 多样性指数介于0.32～2.95，平均值为1.49；Pielou 均匀度指数介于0.16～0.89，平均值为0.55．CCA 分析结果显示，调查海域优势种主要受磷酸盐限制．与历史资料比较发现，该海域浮游植物群落由早期的硅藻占绝对优势向硅藻甲藻联合占优转变．
應用Uterm?hl方法對2012年鞦季渤海和北黃海浮遊植物的物種組成、細胞豐度和群落結構特徵等進行瞭分析，併應用典範對應分析(CCA)對調查海域浮遊植物和環境因子進行瞭相關性分析．本次調查共鑒定齣浮遊植物3門38屬94種，其中硅藻門29屬62種，甲藻門8屬31種，金藻門1屬1種，物種生態習性以溫帶種和廣佈種為主．調查海域浮遊植物細胞豐度介于0.30×103～10.48×103 L-1，平均值為2.79×103 L-1，硅藻主要優勢物種為具槽帕拉藻(Paralia sulcata)和圓篩藻(Coscinodiscus sp.)；甲藻主要優勢種為梭狀角藻(Ceratium fusus)和三角角藻(Ceratium tripos)．浮遊植物群落 Shannon-Wiener 多樣性指數介于0.32～2.95，平均值為1.49；Pielou 均勻度指數介于0.16～0.89，平均值為0.55．CCA 分析結果顯示，調查海域優勢種主要受燐痠鹽限製．與歷史資料比較髮現，該海域浮遊植物群落由早期的硅藻佔絕對優勢嚮硅藻甲藻聯閤佔優轉變．

The species composition,cell abundance and community structure of phytoplankton in Bohai Sea and the North Yellow Sea were studied with Uterm?hl method in Autumn(November)2012. Canonical correspondence analy-sis(CCA)was used to analyze the correlation between phytoplankton and environmental factors in the surveyed area. A total of 94 taxa which belong to 38 genera of 3 phyla were identified,among which 62 species of 29 genera were Baciallariophyta,31 species of 8 genera were Dinophyta,and 1 species of 1,genera was Chrysophyta. The species composition of phytoplankton community were mainly temperate and widely distributed regimes. The cell abundance of the phytoplankton ranged from 0.30×103 to 10.48×103 L-1,and the average value was 2.79×103 L-1. Paralia sul-cata and Coscinodiscus sp. were the main dominant species of Baciallariophyta. Ceratium fusus and Ceratium tripos were the dominant species of Dinophyta. Shannon-Winener diversity index ranged from 0.32 to 2.95,and the average value was 1.49.Pielou’s evenness index ranged from 0.16 to 0.89,and the average value was 0.55. Canonical corre-spondence analysis showed that the most influenicial environmental factor on the dominant species was phosphate. Comparison with historical data found that the phytoplankton community was dominated by diatom in the past,but now by both diatom and dinoflagellate coexisting together.
