摘　　要：本研究以黄河呼和浩特段大黑河和浑河的国控考核断面2016—2023年间水质监测数据为基础,利用单因子评价法、综合污染指数法和Spearman秩相关系数法,对2个国控考核断面水质进行综合评价。评价结果表明:大黑河整体水质逐年改善,浑河整体水质显著提升;3种方法是定性和定量评价的有机结合,评价结果基本一致。In this study,three evaluation methods(i.e.single factor evaluation method,comprehensive pollution index method and Spearman rank correlation coefficient method)were used to evaluate the water quality condition of the Key river basins Daheihe River and Hunhe River in Hohhot section of the Yellow River according to the monitor⁃ing data of the state-controlled examination sections during 2016 to 2023.There result showed that the overall water quality of the Daheihe River has improved yearly,and that of the Hunhe River has improved significantly.The three methods are the organic combination of qualitative and quantitative evaluation,and the evaluation results are basical⁃ly consistent.
