摘 要:对渤海湾浮游动物群落结构进行了分析,结果表明,渤海湾浮游动物全年平均丰度为2651.5个/m3,最大为7 047.2个/m3,最小为328.9个/m3。其中桡足类在各航次中占据大多数,是数量的主要构成者,且呈明显的季节变化。浮游动物主要的高峰期出现在春季,此外,夏秋两季各有一个小高峰。小拟哲水蚤、太平洋纺锤水蚤、长腹剑水蚤和中华哲水蚤是春季的优势种;强壮箭虫和真刺唇角水蚤是夏季的优势种;小拟哲水蚤、强额拟哲水蚤和长腹剑水蚤是秋季的优势种。结合多样性指数的分析方法对渤海湾水质进行评价,结果为:由于陆源排放和养殖业的发展水体受到相当程度污染。It is an important researching maUer that the ecological characteristics of zooplankton in species, distribution, abundance and dynamics to hydrobiology scientist. The result indicated that the abundance of zooplankton ranged from 328.9 ind/m^3 to 2 651.5 ind/m^3 with an average of 2 651.5 ind/ m^3 through the analysis of structure of community in Bohai Bay. The copepod were major components of zooplankton, there was a peak in Spring, besides, there were two small peaks in Summer and Autumn.The species which dominated change seasonally: Paracalanus parvus, Acartiapacifica and Oithona similes were in Spring; Sagim crasss Tokioka and Labidocera euchaeta were in Summer; and Paracalanus parvus, Paracalanus crassirostris and Oithona similes were in Autumn. The showed that the sea area of Bohai Bay had been polluted comparatively by the ordure from land and development of marine product.
