摘要
三沙湾浮游桡足类可分为3种生态类群,在种数和个体密度上均以近岸类群为主。桡足类总个体密度高峰出现在春季5月,低谷出现于冬季2月。主要种真刺唇角水蚤四季皆古优势,而中华哲水蚤、精致真刺水蚤和汤氏长足水蚤之间具明显的季节更替。浮游桡足类总量的时空分布状况及各生态类群的相互演替和平而分布格局与海区内不同水系的运动和推移关系密切。
The copepods in Sansha Bay, Fujian can be divided into three ecological groups, in which the offshore group was the most important according to species number and abundence. The total individual number of copepods was highest in May and lowest in February. The main species Labidocera euchaeta was dominant all the years, but seasonal succession obviously occurs in species of Calanus sinicus, Euchaeta concinna and Calanopia thom psoni. The time and spatial distribution of total individuals, the succesion and distributional trend among the varied ecological groups of copepoda are related to the movement and intensification and decay of different water systems.
