【摘要】 调查南黄海浮游甲藻的种类组成、季节变化、水平分布及其与环境因素的关系,结果表明浮游甲藻类有74种,分隶于8科9属。其中高温高盐种占71.63%,广温广盐种占22.97%。低盐近岸种和冷水性种类各占2.7%。南黄海浮游甲藻细胞总量的季节分布,以夏季7月为最高峰,春季3月为最低谷,并对其生态特征和水文环境因素的关系进行了详细的研究与讨论。钩梨甲藻,赛氏鸟尾藻、圆头角藻、指状角藻和新月角藻等,仅分布于126°E以东、表层(10m)盐度34.00的海域,可作为黄海暖流的指示种。

【Abstract】 This paper reports the composition and distribution of planktonic dinoflagellate inthe Southern Yellow Sea and its adjacent waters(32°~ 34°N,the west of 127°E)during the pe-riod from December 1997 to November 1978. 74 species belonging to 9 genera in families wereidentified, among which 71. 63 % were warm water species, 22. 97% eurythermic species,2. 7 % neritic species and 2. 7 % cold-water species. Seasonal variation of the total number of di-noflagellate shows that the highest peak was in July and the lowest value in March. Theeffects on the numerical distribution and seasonal variation of dinoflagellate were discussed aswell. It is pointed out that some species, Pyr. hamulus, Orn. thurnii, Cer. gravidum, Cerranipes and Cer. lunula etc., only presented in the eastern of 126°E, which was just in agree-ment with the isohaline of 34. 00, and can be taken as indicator species for the Yellow Seawarm current.
