本文报道了１９９１／１９９２年南极夏季在普里兹湾邻近海域浮游植物调查的研究结果。经鉴定共有浮游植物３门２６属７８种；其平均细胞丰度为１２０±１７４×１０５个／ｍ３，密集区分布在６２°Ｓ、７８°～１０３°Ｅ，这一海域其细胞丰度在１１０×１０５～８６４×１０５个／ｍ３之间。根据浮游植物种类组成和细胞丰度百分比的聚类分析，测区浮游植物群落中可划分为四个聚合类群：菱形藻（Ｎｉｔｚｓｃｈｉａ）与赖氏针杆藻（Ｓｙｎｅｄｒａｒｅｉｎｂｏｌｄｉ）、长环毛藻（Ｃｏｒｅｔｈｒｏｎｃｒｉｏｐｈｉｌｕｍ）与翼根管藻（Ｒｈｉｚｏｓｏｌｅｎｉａａｌａ－ｔａ）和翼根管藻与赖氏针杆藻占优势的聚合类群及由海冰习性的菱形藻与近岸性角刺藻（Ｃｈａｅｔｏｃｅｒｏｓ）占优势组成的中山站近岸单一生态类群。文中还讨论了浮游植物丰度与环境因子的关系并对过去数年南极浮游植物的调查结果进行了比较
This paper reports the results of a 1991 and 1992 Antarctic summer survey of phytoplankton in the Prydz Bay. A total of 78 phytoplankton species belonging to 26 genera and 3 phytoplankton species were identified. The average abundance of the phytoplankton species was 120 ± 174 × 10 5 / m 3 and the density ranged from 62 ° S to 78 ° -130 ° E. 110 × 105 ~ 864 × 105 个 / m3 between. According to the phytoplankton species composition and percentage of cell abundance, phytoplankton community can be divided into four aggregated groups: Nitzschia and Synedrareinboldi, Corethroncriophilum ) And Rhizosolenia-ta and the dominant species of Agropyrolactylididae and Reichiella microphylla, and Zhongshan, which is dominated by sea ice habitat Rhizomorph and Chaetoceros Station near the single ecological group. The paper also discusses the relationship between phytoplankton abundance and environmental factors and compares the results of surveys of the Antarctic phytoplankton over the past few years
