摘　　要：2020年8—10月,对大庆连环湖3个中碱度池塘进行浮游动物鉴定以及水环境因子检测,分析了浮游动物的群落结构特征,并运用Pearson相关系数对池塘中浮游动物与水环境因子的相关性进行分析。结果表明:1号、2号、3号池分别鉴定出28、34和28个浮游动物种属,轮虫种类最多,其中原生动物分别为9、11、10个种属,轮虫分别为12、16、15个种属,枝角类分别为5、5、1个种属,桡足类均为2个种属;原生动物优势种10种,轮虫优势种6种;3个池塘水体浮游动物平均丰度分别为10264.89、9416.89和3939.33 ind./L,平均生物量分别为17.03、20.69和8.14 mg/L;3个池塘平均总氮含量为2.69 mg/L,平均总磷含量为0.91 mg/L,试验池塘均为富营养型水体。此研究结果为中碱度养殖池塘水质调控提供了基础数据。From August to October of 2020,zooplankton were identified,water environment factors were detected in three ponds with three medium alkalinity in Lianhuan Lake of Daqing.The community structure characteristics of zooplankton were analyzed,and Pearson correlation coefficient was used to analyze the correlation between zooplankton and water environment factors in ponds.The results showed that 28,34 and 28 zooplankton species were identified in ponds No.1,No.2 and No.3,among which 9,11 and 10 species were protozoa,12,16 and 15 species were rotifers,5,5 and 1 species were cladocera,and 2 species and genera were copepods.The average abundance of zooplankton in the three ponds was 10264.89,9416.89 and 3939.33 ind./L respectively,and the average biomass was 17.03,20.69 and 8.14 mg/L respectively.The average total nitrogen content and average total phosphorus content in three ponds were 2.69 and 0.91 mg/L respectively.And the experimental ponds were all eutrophic water bodies.The study results provided basic data for water quality control of medium alkalinity aquaculture ponds.
