摘要
为了了解徐州市城市湖泊云龙湖浮游动物对水体环境变化的响应,于2012~2013年上、下半年对云龙湖浮游动物群落变化以及相应水体11种理化因子进行了监测分析,并通过冗余分析（RDA）探讨了浮游动物变化与环境因子之间的关系。监测结果表明,4次采样4个点位中共检测到39种微型浮游动物类群,点位间物种群落无明显差异,但年际间物种呈现下降趋势。RDA分析显示云龙湖浮游动物群落变化主要受石油类,DO,SD,BOD5,TN和Chl-a影响,且石油类,DO,BOD5,及Chl-a可能是造成云龙湖浮游动物群落时间差异的主要原因。
In order to study the effect of water environmental factors on the zooplankton community structure in urban lake,the zooplankton community and water eleven Kinds physicochemical properties in Xuzhou Yunlong Lake were monitored biannually from 2012 to 2013. And, redundancy analysis（RDA）was used to discuss the relationship between zooplankton variation and environmental factors. 39 species of zooplankton were identified, and there was no obvious difference in the zooplankton community composition of each sampling site. But, the results of monitoring showed that the number of species in Yunlong Lake tended to reduce gradually from 2012 to 2013. RDA revealed that the variation of zooplankton community structure in Yunlong Lake were mainly influenced by environmental factors including Petroleum, DO, SD, BOD5, TN, and Chla. While, petroleum, DO, BOD5 and Chl-a might be the primary factors that caused temporal disparities of zooplankton community in Yunlong Lake.
