| 2006年7月至2007年6月对太湖贡湖湾大型浮游动物群落结构的季节变化进行了研究,共鉴定出大型浮游动物35种,年均密度为467个/L,年均生物量为1.726mg/L。贡湖湾大型浮游动物优势种为针簇多肢轮虫(Polyarthra trigla)和萼花臂尾轮虫(Brachionus calyciflorus);其中,针簇多肢轮虫年均密度为99个/L,占大型浮游动物总数量的22%,萼花臂尾轮虫年均密度为49个/L,占大型浮游动物总数量的11%。相关分析表明,轮虫数量与颗粒悬浮物浓度(r=-0.603,P<0.05)和桡足类生物量(r=-0.670,P<0.05)呈显著负相关;枝角类数量与轮虫生物量(r=-0.606,P<0.05)显著负相关;桡足类数量与水温(r=0.596,P<0.05)和总磷(r=0.596,P<0.05)呈显著正相关性,与枝角类生物量(r=0.776,P<0.01)极显著正相关。 |

| A study on seasonal variations of macrozooplankton community in Gonghu Bay in Lake Taihu，was conducted from Jul. 2006 to Jun. 2007. Thirty-five macrozooplankton species were identified in Gonghu Bay respectively. The annual average density and biomass of macrozooplankton were 467 ind/L and 1 .726 mg/L in Gonghu Bay respectively. In Gonghu Bay，Polyarthra trigla was dominant species，with annual average density 99 ind/L, constituting 22% of the total macrozooplankton;Brachionus calyciflorus was also dominant species，with annual average density 49 ind/L，representing 11%of the total macrozooplankton. The correlation analysis indicated that there were significant negative correlations between the abundance of rotifer and concentration of suspended solids(r= -0. 603 , P<0.05)and between the abundance of rotifer and the biomass of copepod(r= -0. 670 , P<0.05);the abundance of cladoceran was notably negatively related to the biomass of rotifer( r= -0. 606 , P<0. OS);the a-bundance of copepod was significantly positively related to water temperature(r=0. 596，P<0. 05)，total phosphorous(r=0. 596 , P<0.05)and the biomass of cladocearan(r=0. 776 , P<0.01). |
