摘要
利用大型底栖动物分类单元数、EPT优势度指数等调查评价方法,对凉水河底栖动物的现状进行评价。结果表明,凉水河各采样点底栖动物多样性较差,Shannon-Wiener多样性指数变化范围为0.21~1.40,底栖动物种类较为单一。
The present situation of zoobenthos in Liangshui river were evaluated by the macrobenthos taxonomic units number,EPT classification unit ratio,BMWP index,and Berger-Parker dominance index.The results showed that the diversity of zoobenthos in each sampling sites from Liangshui river were poor.The Shannon-Wiener diversity index was 0.21~1.40,and the species of zoobenthos was single relatively.
