中文摘要：
根据1997～2000年东海23°30′～33°00′N、118°30′～128°00′E海域4个季节海洋调查资料，对东海栉水母数量变化和地理分布特征作了探讨。结果表明，东海栉水母平均丰度秋季（6．3ind·（100m^3）^-1）〉春季（1．6ind·（100m^3）^-1）〉冬季（1．4ind·（100m^3）^-1）〉夏季（0．6ind·（100m^3）^-1）。调查海域鉴定到种的栉水母共有6种，其中球型侧腕水母（Pleurobrachia globosa）是东海的主要种类；掌状风球水母（Hormiphora palnata）和瓜水母（Beroe cucumis）是常见种；带水母（Cestum sp．）是次常见种；蝶水母（Ocyropsis crystalline）和卵型瓜水母（Beroe avata）是稀有种。东海栉水母系暖水性浮游动物类群，其数量变化与东海暖流势力活动过程中的携带有密切的联系。球型侧腕水母分布较为广泛。是适应环境能力较强的种类；掌状风球水母、蝶水母和卵型瓜水母柑反，仅适应有限的环境；瓜水母和带水母适应能力介于以上两类栉水母之间。
英文摘要：
Based on the investigations in four seasons from 1997 to 2000, this paper studied the seasonal quantitative variation and geographical distribution characters of Ctenophora in East China Sea （23°30′-33°00′N318°30′～ 128°00′E）. The results showed that the abundance of Ctenophora peaked in autumn （6.3 ind· （ 100 m^3 ）^-1 ）, followed by in spring （1.6 ind·（100 m^3）^-1）, winter （1.4 ind·（100 m^3）^-1）, and summer （0.6 ind·（100 m^3）^-1）. A total of six species were observed, among which, Pleurobrachia globosa was the most important species, Hormiphora palnata and Beroe cucumis were the common spades, Cestum sp. was the subordinate species, while Ocyropsis crystalline and B. avata were the rare species. The Ctenophora in East China Sea was a kind of warm water species, because its quantitative variation had a dose relation with the motion of warm water current, and the key factor af- fecting Ctenophora abundance was warm water current but not the seasonal change of temperature. In all species of Ctenophora, P. globosa had stronger adaptability to its environment, followed by Cestum sp. and B. cucumis, and H, palnata, Ocyropsis crystalline and B, avata.
