摘要
１９９０年５月和１１月在马鞍列岛附近海域进行两次采样调查，共检出浮游植物８０种，隶属于３６属。春季浮游植物的平均丰度为６．４×１０４个／ｍ３，最高达２０８．６×１０４个／ｍ３，优势种为夜光藻和角藻；秋季浮游植物平均丰度为７４４０．４×１０４个／ｍ３，最高达２０７６１．２×１０４个／ｍ３，优势种为中肋骨条藻，其丰度已达到赤潮发生的临界状态。由富营养化综合指数分析表明，５月该水域未处于富营养化，而１１月则完全处于富营养化状况。该水域春秋两季均存在多种赤潮生物。
study on phytoplankton in Ma'an Islands water was carried out in May and October,1990. 80 species belonged to 36 genera were identified in total. Among them, 29 are red tidecausative species. The mean phytoplankton density in spring was 6. 4 ×104 cells/m3 and dominant phytoplankton were dinoflagellates. The mean phytoplankton density in autumn was7440. 4×104 cells/m3 and dominant phytoplankton were diatoms. The main red tide causativespecies in the study area are Noctiluca scintllans, Skeletonema costatum, Prorocentrum triestinium and Nitzschia pungens.
