摘要
鉴定浮游植物种类54属184种（含变种和变型），其中暖水种为140种（占76．5％）．硅藻类和甲藻类等浮游植物的平均总细胞密度为198．71×102个／m3；蓝藻类藻丝体平均密度为44．55×102条／m3．浮游植物各类别的分布与水域的磷酸盐含量、黑潮以及其他水系（涌升水和沿岸水等）等相关；蓝藻类的束毛藻（Trichodesmium）的分布还与50m以浅水体的平均水温关系密切．
A total of 184 phytoplankton species which belong respectively to 54 genera is identified. Most of those species recorded belonged to warm water forms (accounted for 76. 5 % ). The cell density of diatoms and dinoflagellates averaged 198. 71×102 cells/m3. The filament density of blue-green algae averaged 44. 55×102 filaments/m3. The distribution of each group of phytoplankton is correlated to both phosphate concentration in sea water and the influence of Kuroshio and other water systems (upwelling and coastal water, etc. ) etc. The distribution of blue-green alga Trichodesmium has close correlation to the mean water temperature in the upper 50 m as well.
