摘　　要：利用1981年2、5、8和11月4个航次的海洋调查资料,对黄海南部及东海(28°00′～34°00′N、121°00′～127°00′E)水域中、小型浮游桡足类隆剑水蚤科(Oncaeidea)的种类组成和分布特征进行了初步分析。研究结果表明,调查水域共出现隆剑水蚤9种,其中等刺隆剑水蚤(Oncaeamediterranea)、背突隆剑水蚤(Oncaeaclevei)和角突隆剑水蚤(On caeaconifera)为主要优势种。夏季丰度最高(60.38ind·m-3),秋季次之(15.16ind·m-3),冬季最低(2.34ind·m-3)。通过对同步温度和盐度资料分析后发现,隆剑水蚤主要分布在受台湾暖流和黑潮暖流影响的高温、高盐区域,其中等次隆剑水蚤可作为暖流的指示种。Oncaeidae is important small copepods in the East China Sea and the Yellow Sea, and is the main food for fish larvae. But up to now no report was published on their ecological characteristics. Based on the data collected in the East China Sea and the southern Yellow Sea(28°00′-34°00′N,121°00′-127°00′E) in spring, summer, autumn and winter, 1981, the species composition and distributing characteristics of Oncaeidae were analyzed. Nine species of Oncaeidae were identified, including O. mediterranea, O. clevei, O. conifera, O. media, O. venusta, O. minuta, O. similis, O. dentipes and O.ornata, among which O. mediterranea, O. clevei and O. conifera were main dominantal species. The first abundance peak (60.38 ind·m-3)occurred in summer and second peak (15.16 ind·m-3)in autumn and the lowest (2.34 ind·m-3)in winter. Their horizontal distributions were not equational that cluster center was obviouse. In spring they distributed in a small scale; in summer they covered all investigated sea water, and mainly distributed in off sea water in winter. The distributions of Oncaeidae were related to the distribution of surface temperature and salinity and most of them intended to cluster in high temperature and high salinity area affected by Taiwan warm curent and kuroshio; some certain species such as Oncaea mediterranea may serve as indicting species of warm current.
