摘要
１９９０年４月和１０月在南麂列岛附近海域进行了两个航次的浮游植物采样调查，共检出浮游植物９７种，隶属于３６属。春季同样浮游植物的平均丰度为２９．７×１０４个／ｍ３，水样浮游植物平均丰度达５２７６０×１０４个／ｍ３。优势种有三鳍原角藻Ｐｒｏｒｏｃｅｎｔｒｕｍｔｒｉｅｓｔｉｎｉｕｍ、夜光藻Ｎｏｃｔｉｌｕｃａｓｃｉｎｔｉｌｌａｎｓ和威氏圆筛藻Ｃｏｓｃｉｎｏｄｉｓｃｕｓｗａｉｌｅｓｉｉ。秋季浮游植物同样的平均丰度为３２．５×１０４个／ｍ３；水样浮游植物平均丰度为９２８×１０４个／ｍ３。优势类群有角刺藻Ｃｈａｅｔｏｃｅｒｏｓｓｐｐ、圆筛藻Ｃｏｓｃｉｎｏｄｉｓｃｕｓｓｐｐ、角藻Ｃｅｒａｔｉｕｍｓｐｐ、海毛藻Ｔｈａｌａｓｓｉｏｔｈｒｉｘｓｐｐ、根管藻Ｒｈｉｚｏｓｏｌｅｎｉａｓｐｐ、骨条藻Ｓｋｅｌｅｔｏｎｅｍａｃｏｓｔａｔｕｍ等。该海区春秋两季均存在多种赤潮生物。
A survey on phytoplankton was carried out in the waters near Nanji Archipelago in April and October, 1990. 97 species belonged to 36 genera were identified in total. The mean density of the net phytoplankton and of phytoplankton in water samples in spring was 29.7 ×104and 52 760× 104 cells/m3 respectively, and the dominant species were Prorocentrum triestinium, Noctiluca scintillans and Coscinndiscus wailesii. The mean density of the net phytoplankton and of phytoplankton in water samples in autumn was 32. 5× 104 and 928× 104 cells/m3 respectively, and the dominant species were Chaetoceros spp., Coscinodiscus spp., Rhizosoleniaspp., Thalassiothrix spp. and Skeletonema costatum and so on. Some red tide plankton occurred in the two seasons.
