摘要
基于2006年7-8月在南黄海西部(32°～37°N,124°E以西)进行的137个站位的浮游动物大面调查,研究了浮游动物的种类组成、丰度、生物量、优势种及生态环境指示种的分布及影响因素。结果显示,浮游动物种类组成较以往多,中华哲水蚤对浮游动物丰度贡献最高,超过50%,生物量也明显高于以往,本研究胶质性浮游动物生物量超过非胶质性浮游动物。优势种组成差别不大,中华哲水蚤存在2个丰度高值区,一个位于叶绿素a浓度较低的黄海冷水团内,一个位于海区南部;强壮滨箭虫出现频率最高,高丰度区与中华哲水蚤不同,主要位于山东半岛南岸至海州湾外侧;细足法主要分布在34°N以北的冷水团范围内,在盐度低于31的海区几乎绝迹;太平洋磷虾主要分布在33°～35°N的深水区。暖水种精致真刺水蚤和肥胖软箭虫在海区南部较多,与北向的长江冲淡水和台湾暖流有关,其分布北限受到南向的苏北沿岸流和黄海冷水团的影响,这两种浮游动物在南黄海的分布可以反映上述海流的相互作用。
Based on the cruise in the Southern Yellow Sea （SYS） including 137 zooplankton sampling stations in the summer, 2006, zooplankton species composition, the distribution of zooplankton abundance, biomass, dominant species and indicator species of ecological environment and their influencing factors were studied. Results showed that： species composition was higher than studies in the SYS before; the abundance of Calanus sinicus was the hihghest and exceeded 50% in the total abundance. The biomass was also much higher than previous studies and in this study, the biomass of gelatinous zooplankton was higher than the non-gelatinous zooplankton. The composition of dominant species was similar to studies before. C. sinicus had two high abundance areas, one was in the inside of the Yellow Sea Cold Water Mass （YSCWM） where the Chl a concentration was lower and the other was located in the southern sea area; the occurrence frequency of Aidanosagitta crassa was the highest and its high abundance ar- ea occurred from the southern coast of Shandong Peninsula to the east of Haizhou Bay, which was different from that of C. sinicus; Thernisto gaudichaudi mainly distributed in the north of the 34~N where was influenced by the YSCWM and the species almost disappeared where the salinity was lower than 31 ; Euphausia pacifica primarily distributed in the deep water area between 33^-35~N. Euchaeta concinna and Flaccisagitta enflata distributed in the south of 34°N,their distribution pattern might be correlated with the northward current--Changjiang Diluted Water and the Taiwan Warm Current, the northern border of these two species was affected by the southward Subei Coastal Current and the YSCWM. The distribution patterns of the two species can indicate the interactions of the oceanic current mentioned above.
