| 摘 要： | 1998年5、8和10月渤海近岸浮游植物调查结果显示,已鉴定的浮游植物有2门23属53种,其中硅藻门占绝对优势,计有19属45种,其次是甲藻门有4属8种,且浮游植物种类组成及其优势种类的季节变化比较明显。浮游植物的月平均数量为56.73×10~4 cells/m3,其中,硅藻门的平均数量为55.21×10~4 cells/m3,占浮游植物总量的97.3％,甲藻门的平均数量为1.52×10~4 cells/m3,占浮游植物总量的2.7％。渤海近岸浮游植物数量分布具有明显的季节变化,数量高峰出现在春季(5月)和秋季(10月)。与历史同期调查资料相比,渤海近岸浮游植物数量的年间变化亦较明显。

| Abstract: | The species composition, distribution, their seasonal and interannual variations of phytoplankton in Bohai Sea were studied according to the data acquired from the cruises in May, Au-tumn and October, 1998. The results showed there were 2 phylum,23 genera, and 53 (mostly warm inshore) species of phytoplankton in the Bohai Sea. The cells and species of Bacillariophyta (19 genera and 45 species) were absolutely predominant in the species copasition, and those of the Cer-atium (4 genera and 8 species )took second place. The peak phytoplankton abundance was observed in Spring (May) and Autumn (October). Compared with 1982-1983 and 1992 - 1993, there was a fare reduction in phytoplankton abundance and species in 1998. |
