Species composition and cell abundance of phytoplankton, and its relations with environmental factors were investigated in the Changjiang River estuary of east China sea (30 degrees 50'-31 degrees 50'N, 121 degrees 50'-123 degrees 00'E). A total of 110 taxa belonging to 45 genera of phytoplankton in the investigation area were identified. The main species of phytoplankton resulted in red tide were Skeletonema costatum and Prorocentrum dentatum, etc. Phytoplankton abundance in the day was higher than that at night. The vertical distribution of phytoplankton in different water bodies was not obvious. The ecological groups of phytoplankton were freshwater group, estuarine and brackish water and low salinity group in the coast, high salinity and warm water group in off-sea, and widely ranging group. The abundance of phytoplankton in the Changjiang River estuary was 1.6 x 10(3)-75.2 x 10(3) ind.dm-3. The species composition and cell abundance of phytoplankton were related to the freshwater pouring into the Changjiang River estuary. The three waters in the area affecting the distribution of phytoplankton were the Changjiang River estuary water, freshwater, and warm water from outsea.
对中国东部海域长江河口（北纬30°50′-31°50′，东经121°50′-123°00′）浮游植物的种类组成、细胞丰度及其与环境因子的关系进行了调查。调查区域共鉴定出浮游植物45属110种。引发赤潮的主要浮游植物种类有中肋骨条藻和具齿原甲藻等。浮游植物丰度白天高于夜间。不同水体中浮游植物的垂直分布不明显。浮游植物的生态类群有淡水类群、河口和沿岸低盐类群、外海高盐暖水类群以及广布类群。长江河口浮游植物丰度为1.6×10³-75.2×10³个/立方分米。浮游植物的种类组成和细胞丰度与长江河口的淡水注入有关。该区域影响浮游植物分布的三种水体是长江河口水体、淡水和外海暖水。
