白河堡水库浮游动物调查与水质评价

Zooplankton Investigation and Water Quality Assessment in Baihepu Reservoir

通过调查白河堡水库不同样站浮游动物的生态状况,对白河堡水库的水质污染进行评价.结果表明:白河堡水库浮游动物的种类组成以原生动物为主;浮游动物具有原生动物数量最多,轮虫次之,枝角类与桡足类数量较少的特点.浮游动物的优势种群有急游虫Strombidiumuiride、钟形钟虫Vorticella campanula、针簇多肢轮虫Polyarthratrigla、螺形龟甲轮虫Keratella cohlearis、矩形龟甲轮虫Keratella quadrata、颈沟基合溞Bosminopsis deitersi、长额象鼻溞Bosmina longirostris、沟渠异足猛水溞Canthocamptus staphylinus等.白河堡水库浮游动物较丰富,大部分库区水体清洁,有的轻度污染.

The investigation results of zooplankton at different stations in Baihepu reservoir were reported to assess water quality of the reservoir. The investigation results indicate that the species of zooplankton are mainly composed of protozoa, rotifer take the second place, freshwater cladocer and copepod least. Zooplankton was primarily predominated by Strombidiumuiride , Vorticella campanula, Polyarthratrigla , Keratella cohlearis , Keratella quadrata , Bosminopsis deitersi , Bosmina longirostris and Canthocamptus staphylinus. The zooplankton is abundant in the Baihepu reservoir, some water body of main reservoir is clear, some water body shows a little pollution.
