摘要: 根据2001年8月对胶州湾海域进行的为期2d的大面积调查资料,对浮游植物的群落结构进行了初步研究.结果表明,浮游植物群落主要由沿岸暖水性种类组成,以硅藻为主,共34种;还有少量的甲藻7种和绿藻1种.湾中央水域出现的物种数最多,为37种;湾边缘最少,仅出现10种.细胞数量的密集区出现在湾东部边缘水域,最高值为6.96×108个cell·m-3;低值区出现在湾口,最低值仅为3.18×106个cell·m-3.调查期间浮游植物的物种多样性及其均匀度的最低值均出现在湾东部边缘水域;高值区出现在湾口和湾中央水域.胶州湾海域水团运动和水体富营养化程度是影响浮游植物群落分布的主要环境因素.

Abstract: Based on two days survey in August,2001 in Jiaozhou Bay,the structural characteristics of phytoplankton community during harmful algae bloom was studied. The results showed that phytoplankton community was composed mainly by the coastal warm species, which were dominated by the diatom including37 species. Only 7 Pyrrorophya and 1 Chlorophyta species were identified. The highest value of species number appeared in the central of Jiaozhou Bay, which included 37 species, but the lowest value in the edge of Jiaozhou Bay was only 10 species. The highest value of cell abundance appeared in the eastern waters of Jiaozhou Bay, being 6.96?108cell穖-3,and the lowest value appeared in the mouth of Jiaozhou Bay,being 3.18?106 cell穖-3.The diversity and eveness of phytoplankton was the lowest in the eastern waters of Jiaozhou bay, but was higher in the mouth and the central of Jiaozhou Bay. Water mass movement and eutrophication were the main factors affecting the distribution of phytoplankton community in Jiaozhou Bay.

Key words: Phytoplankton, Species diversity, Cell abundance, Jiaozhou Bay
