基于1959、1984、1990与2004年曹妃甸海域的历史调查资料，分析了曹妃甸海域浮游动物群落的长期变化特征。结果表明：曹妃甸海域浮游动物生物量和丰度整体上呈现增长的趋势，春季尤为显著。2004年春季生物量和丰度分别达到了1093.8 mg/m3和775.8 ind/m3，为1959年的4.75倍和5.15倍。浮游动物丰度的季节变化由1959年的夏季高于春季转变为2004年的春季高于夏季的趋势。曹妃甸北部和东北部海域春、夏两季浮游动物生物量和丰度均较高，尤其东北侧龙岛附近海域形成一个极高值区。浮游动物优势种季节变化明显，春季主要为中华哲水蚤（Calanus sinicus）与双毛纺锤水蚤（Acartia bifilosa）；夏季以强壮箭虫（Sagitta crassa）为主。此外，水母类浮游动物在夏季明显增多。

Based on the investigations in 1959, 1984, 1990 and 2004, this paper analyzed long-term variation of zooplankton community in the sea area of Caofeidian, Hebei Province, China. The results showed that the biomass and abundance of zooplankton increased significantly during the past 45 years, especially in spring. The biomass and abundance of zooplankton in spring of 2004 were 1093.8 mg/m3 and 775.8 ind/m3, respectively, which were 4.75 times and 5.15 times than those in 1959. The zooplankton abundance in summer was more than that in spring in 1959, but the zooplankton abundance in summer was less than that in spring in 2004. In spring and summer, the zooplankton biomass and abundance were higher in the northern and northeastern sea area of Caofeidian, especially the maximum values were in the sea area of Dragon Island . The dominant zooplankton species were different, with Acartia bifilosa and Calanus sinicus in spring and Sagitta crassa in summer. Besides, compared with that in 1984 and 1990, the abundance of jellyfish in the coastal area of Caofeidian increased significantly in summer of 2004.
