摘要
报道了北京地区几条主要河流蜉蝣稚虫的种类分布，探讨了其群落结构特征及其与水体环境质量之间的关系，运用种类多样性指数和聚类分析方法对各水体质量状况进行分类评价，结果表明白河和拒马河质量为最好，其余依次为永定河、清水河上游、潮河和清水河。
Species distribution and community structure of mayfly naiads in one site respond to the local aquatic environmental condition closely.The water qua lity of main streams in Beijing area was evaluated by using diversity index,abundance index and cluster analysis method.The result shows that the wa- ter quality of Bai He River and Ju Ma He River is the best,all others are as following sequencei Yong Ding He River,the upreaches of Qing Shui He River,Chao He River and down-reaches of Qing Shui He River.This result is basically consistent with field situation.
