摘　　要：2021年5月对阿坝州黄河上游、黑河、白河3条河流的大型底栖动物以及水质样本进行采集,并对其物种优势度、Shannon-Wiener指数以及BI指数进行分析。结果表明,阿坝州黄河流域共采集到2门17种底栖生物,其中节肢动物有14种,软体动物有3种,一般耐污种钩虾(Gammaridea)在3条河流中均为优势种。Shannon-Wiener指数结果显示,阿坝州黄河干流、黑河、白河Shannon-Wiener指数分别为2.50、2.53、2.02,水体均属于轻度污染水质标准;3条河流的BI指数分别为3.81、4.93和4.29,均属于清洁水质标准;水质指标理化分析结果显示,3条河流均属于国家II类水质标准。综合分析可得,阿坝州黄河上游水质均处于清洁的健康状态。In May,2021,macrobenthos and water quality samples were collected from the upper reaches of the Yellow River,Hei River and Bai River in Aba Prefecture,and their species dominance,Shannon-Wiener index and BI index were analyzed.The results showed that a total of 17 species of macrozoobenthos were collected in 3 rivers,belonging to the phylum Arthropods and Molluscs.Among them,there are 14 species of arthropods,3 species of molluscs,and general pollution-resistant species of hook shrimp(Gammaridea)was the dominant species in all 3 rivers.The Shannon-Wiener index results showed that the Shannon-Wiener indexes of the main stream of the Yellow River,Hei River and Bai River in Aba Prefecture were 2.50,2.53 and 2.02 respectively,and the water bodies belonged to the slightly polluted water quality standard.The BI indexes of the three rivers were 3.81,4.93 and 4.29 respectively,which belonged to the clean water quality standard.The physical and chemical analysis results of water quality indicators showed that the three rivers belonged to the national grade II water quality standard.Comprehensive analysis shows that the water quality of the upper reaches of the Yellow River in Aba Prefecture is in a clean and healthy state.
