摘要
本文论述了青龙河底栖生物种类、数量、分布和结构等特点及其与环境因子间的关系。应用Beck、Gleason、Shannon、Simpson等生物指数对水质状况进行评价。结果表明青龙河除个别断面受污染外,大部分河段属尚清洁水。
In this paper, the kinds of benthos in Qinglong River,their quantity, distribution, composition and relation with environmental conditions are discussed, and the water qualityof the river is assessed by Beck, Gleason, Shannon, Simpson and other biotic indices. The results show that the BMC are chiefly composed of three kinds of benthos: aquatic insects, annelida and mollusca, and except specific transects, most parts of the river are of clean water.
