徐州万寨港夏季浮游动物群落结构及水质评价

对徐州京杭大运河万寨港夏季浮游动物群落结构特征、种类组成、物种多样性进行了研究,并对其水质进行了评价。研究结果表明:浮游动物涉及3门21属27种。浮游动物中原生动物7属8种,占29.6%;轮虫类7属9种,占33.3%;枝角类4属6种,占22.2%;桡足类3属4种,占14.8%。优势种主要有绿眼虫(Eutreptia viridis)、旋轮虫(Philodina sp.)、裂痕龟纹轮虫(Anuraeopsis fissa)、长额象鼻溞(Bosmina longirostris)、短尾秀体溞(Diaphanosoma brachyurum)和长肢秀体溞(D.leuchtenbergianum)。对水质评价结果表明,生物监测技术方法简单直观,与化学监测的结果基本一致。监测结果显示万寨港水域属于轻至中度污染。

Zooplankton Community Characteristics and Water Pollution Evaluation in the Wanzhai Harbor in Summer

The investigation of zooplankton community in the Wanzhai harbor had been carried out in summer and the water quality of was evaluated.27 species of zooplankton were found,including 8 species of protozoa(29.6%), 9 species of rotifera(33.3%), 6 species of cladocera(22.2%) and 4 species of copepoda(14.8%).The dominant species were Eutreptia viridis, Philodina sp., Anuraeopsis fissa, Bosmina longirostris, Diaphanosoma brachyurum and D.leuchtenbergianum.Evaluation result indicated that biological monitoring technical method was feasible and simple audio-visual, and was basically coincident with the chemical monitoring result.The water quality of Wanzhai harbor was subjected to light-medium pollution.
