摘 要 ：根据对漳泽水库增温水域的轮虫调查,发现轮虫有33种,平均密度262.5个/1,生物量为0.0631mg/1。并运用相关、回归等方法分析了轮虫的群落特征,结果表明:在20—25℃温度范围内,温度增加,群落多样性指数和均匀度指数也增加;温差越大,群落的种类相似性系数越小;温度对不同种类的轮虫影响不同,两种优势种针簇多肢轮虫(Polyarthra trigla)和沟痕泡轮虫(Pompholyx sulcata)对温度呈现出显著的相关性,其回归方程分别为:Y=362.21-13.99T和Y=-1005.9+49.886T;随着温度增加,优势种从针簇多肢轮虫向沟痕泡轮虫转变。

Abstract:Effect of the warm water drained off from a power station on the rotifer community has been studied in this paper. The water temperature is ranged from 20℃ to 25℃.The results from the study shows that the diversity index is getting higher with the increase of water temperature. The population density of dominant species is correlative with the water temperature. The regression equations are as follows : polyarthra trigla , Y = 362. 21 - 13. 99T; pompholyx sulcata ,Y= -1005. 9 + 49. 886T. The dominant specie...
