摘要:
2007年11月至2008年10月对西凉湖浮游动物进行了4次调查, 共检出浮游动物224种, 其中原生动物112种, 轮虫90种, 枝角类15种, 桡足类7种.秋季浮游动物物种数最多, 为111种, 冬季最少, 为75种, 春季和夏季分别为107种和88种.冬季浮游动物丰度最高, 为126731ind./L, 春季最低, 为71356ind./L, 夏季和秋季分别为109743ind./L和107650ind./L, 原生动物和轮虫的丰度是西凉湖浮游动物丰度的主体.浮游动物群落结构和环境因子的典型对应分析表明, 水温、pH、水深、总磷、化学需氧量和溶解氧是与西凉湖浮游动物群落结构相关性较强的环境因子.冬季浮游动物群落结构与总磷、化学需氧量和溶解氧呈显著正相关;春季、夏季、秋季三个季节的浮游动物群落结构与pH、水温和水深呈显著正相关, 表明西凉湖浮游动物群落结构的季节变化与水温及营养状况密切相关。

Abstract:
Four zooplanktonic investigations were carried out from November 2007 to October 2008 in Lake Xiliang.Totally,224 species of zooplankton including 112 species of protozoa, 90 species of rotifer, 15 species of cladocera,and 7 species of copepoda were found.The zooplankton species ranged from 75 to 111,with the lowest value(75) occurring in winter,and the highest one (111) in autumn.The density of zooplankton was the highest in winter(126731ind./L),and the lowest in spring(71356ind./L).The densities of zooplankton in summer and autumn were 109743ind./L and 107650ind./L,respectively,and the abundance of protozoa and rotifer were on predominance.The structure of zooplankton community was analyzed in relation to water quality pa-rameters by canonical correspondence analysis(CCA).Temperature,pH,water depth,and the concentrations of TP,COD and DO were strongly correlated with the zooplankton community structure.The parameters that demonstrated a strong correlation with the zooplankton community structure differed among seasons, suggesting that the seasonal variations of zooplankton community struc-ture were related closely to both the water temperature and water trophic status in Lake Xiliang.
Key words:  Zooplankton  community structure  water quality  Lake Xiliang
