摘  要:
于2007年对辽宁省汤河水库浮游动物群落结构的时空格局进行了调查。结果表明:共检出浮游动物53个种属,包括原生动物14个,占26.42%;轮虫31个种属,占58.49%;枝角类2个种属,占3.77%;桡足类6个种属,占11.32%;以轮虫占优势,主要为广布多肢轮虫Polyarthra vulgaris、螺形龟甲轮虫Keratella cochlearis等;浮游动物密度平均为1 521个/L,生物量平均为1.78 mg/L;生物多样性指数为0.484~3.122,生物量水平分布为下游>中游>上游,垂直分布没有明显规律,总体上底层生物量较高。

摘  要:
The community structure and spatio-temporal pattern of zooplankton were studied in Tanghe Reservoir in 2007.The results showed that 53 zooplankton species were observed,including 14 species of protozoa,accounting for 26.42% of the total species;31 species of rotifera,accounting for 58.49%;2 species of cladocera,accounting for 3.77%;and 6 species of copepoda,accounting for 11.32%.Rotifera was the dominant species composition of the zooplankton,such as Polyarthra trigla and Keratella cochlearis.The annual average density and biomass were found 1 521 ind./L and 1.78 mg/L,the diversity index of zooplankton 0.484-3.122,and the biomass were found as the following: downstream>midstream>upstream.There was no regularity of biomass vertical distribution of zooplankton in the reservoir,with the higher biomass at the bottom.
