| 摘 要： | 2006年10月至2008年5月,在甘肃徽县水阳江铅锌污染段选择4个样点,分别在3个水期采集水样,研究了纤毛虫物种多样性及群落结构.共鉴定到纤毛虫52种,隶属于3纲12目29科33属.利用纤毛虫群落特征指标对水阳江铅锌污染段的水质进行了初步评价.综合评价结果显示,4个样点受污染程度为县城＞厂区＞牟坝＞对照,污染级别为中度至重度.初步筛选出瓜形膜袋虫(Cyclidium citrullus)、尾草履虫(Paramoecium caudatum)、薄漫游虫(Litonotus lamella)作为铅锌污染水体的指示物种.

| Abstract: | Species diversity and community structure of ciliates in the Pb-Zn-Contaminated section of the Shuiyangjiang River were studied during the period from October 2006 to May 2008,using water samples collected from 4 sampling sites in that section in 3 different periods.In the water samples,52 species of ciliates,sorted into 3 classes,12 orders,29 family and 33 genus,were identified,based on which water quality of that section of the Shuiyangjiang River was preliminarily evaluated.Results show that pollution of... |
