摘要: 在水质酸化和模拟酸雨试验中,共出现浮游动物17种,其中包括轮虫9种、枝角类6种和桡足类2种.在pH5.0—8.3各试验组出现种类数(10—13种)和个体数(223.0—334.5个·L-1)较多,而在pH3.0和4.5试验组出现种类数(5—9种)和个体数(16.8—182.0个·L-1)较少,表明pH5.0以下对浮游动物群落有明显的影响.从不同类群出现所占比例看,在pH5.5以下,随着pH的下降,存在着轮虫逐渐取代桡足类的趋势.

Abstract: In the experiments of water quality acidification and simulated acid rain, 17 species of zooplankton (including9 species of Rotifera, 6 species of Cladocera and 2 species of Copepoda) are found. The results show that the numbers of species (10-13) and individuals (223.0-334.5L-1) are larger at pH 5.0-8.3 and less (5—9 and 16.8—182.0L-1) respectively at pH3.0 and 4.5, indicating that there are significant effects on zooplankton community below pH 5.0. The occurrence frequency of various species show that Copepoda can be gradually replaced by Rotifera below pH 5.5.
