摘要
本文根据1983年2月至1984年1月在九龙江口采集的浮游动物样品,并参考1979年2月以来所采的样品,分析报道了该海区枝角类的种类组成和数量分布.共鉴定枝角类31种,以淡水类群占优势,种数季节分布为双周期型,总量分布为单周期型,种数和总量在河口上部数量高,在口部数量低。文中还讨论了其分布与环境因素的关系。
The analysis of the samples collected during Feb. 1983～Jan. 1984 at eight stations in the Jiulong River Estuary, Fujian shows the existence of 31 species of Cladocera in the survey region, of which fresh-water ecological group is the dominant. The seasonal distribution of total abundance and the number of species of Cladocera have one and two peaks respectively. From the estuarine head to the mouth the total abundance and the number of species of Cladocera decrease gradully with increasing salinity. The effect of environment facters on the distribution of Cladocera is discussed.
