摘要
在对潮河和白河北京境内段底栖动物调查基础上,采用群落分析法并运用BI指数和Shannon-Wiener多样性指数进行水质评价。结果表明:本次共采集底栖动物44种,水生昆虫及幼虫占比最大。底栖动物种类丰富度白河优于潮河。河流评价结果显示,潮河和白河水质整体为优。BI指数法评价中,潮河和白河以清洁为主。Shannon-Wiener多样性指数评价结果中,白河以轻污染为主,潮河以中污染为主。BI指数法适用性较好,而且评价结果较为准确,评价结果对潮河、白河水质判别具有借鉴作用。
Based on the investigation of the zoobenthos in the Beijing section of Chao River and Baihe River,this paper adopted the community analysis method and used the biodiversity index and Shan⁃non-Wiener diversity index to evaluate the water quality.The results showed that 44 species of the zoob⁃enthos were collected,and the aquatic insects and larvae accounted for the largest proportion.The species richness of zoobenthos in the Baihe River was better than that in the Chao River.The results of river eval⁃uation showed that the overall water quality of the Chao River and Baihe River was generally good.The BI index evaluation stated that the Chao River and Baihe River were mainly clean.The Shannon-Wiener di⁃versity index evaluation stated that the Baihe River was mainly light pollution,and the Chao River was mainly medium pollution.The BI method had better applicability and the evaluation results were more ac⁃curate,which could be used as a reference for water quality discrimination of the Chao River and Baihe River.
