| 摘 要： | 2004年9月到10月间在南海北部海区对微型浮游动物的种类组成进行了调查,同期运用现场稀释法,以叶绿素a为监测对象,估计了该海区内微型浮游动物摄食率和摄食压力的水平。结果表明,南海北部海区纤毛虫群体中以多膜纲寡毛目为主,有16种,其中寡毛亚目纤毛虫4种,砂壳亚目纤毛虫11种。各站纤毛虫丰度比较低,在9~102ind/m3之间。浮游植物瞬时增长率(k)在0.03/d~2.13/d之间;微型浮游动物的摄食率(g)在0.01/d~1.06/d之间。微型浮游动物对浮游植物现存量的摄食压力(Pi)在0.089%~65.23%之间,对初级生产力的摄食压力(Pp)在33.63%~86.04%之间。微型浮游动物的摄食水平主要受其丰度的影响,同时微型浮游动物对浮游植物现存量和初级生产力的摄食压力显示,在南海北部海区微型浮游动物在初级生产力传递方面具有重要的科学意义和研究价值。

| Abstract: | Microzooplankton community composition in the north of South China Sea was investigated during autumn (between September and October), 2004. Dilution technique using chlorophyll a (Chl a) was employed to estimate grazing rates and grazing pressure. The results showed that Polymenophorea Oligotrichida was the dominant group with 16 species, and there were 4 species in Oligotrichina and 11 species in Tintinnina. The ciliates abundance ranged from 9 to 102 ind/m3. Instantaneous growth rates of phytoplankton (k) varied from 0.03 / d to 2.13 / d. Grazing rates of microzooplankton(g) ranged between 0.01 / d and 1.06 / d. The grazing pressure on initial phytoplankton stock (Pi) and primary production (Pp) was 0.089 % - 65.23 % and 33.63 % - 86.04 %, respectively. The grazing of microzooplankton was mainly limited by ciliates abundance. Results of grazing pressure on primary production indicated that microzooplankton played an improtant role in transmitting primary production in the north of South China Sea. |
