摘要
依据大黑河呼和浩特段2013—2022年间的水质监测数据,采用单因子评价法、综合污染指数法及Spearman秩相关系数法对大黑河水质状况进行综合分析评价,为全面掌握大黑河水环境质量变化趋势提供技术支撑。分析发现,近十年来大黑河水质污染状况变化显著,水环境质量改善明显。
According to the monitoring data of water quality in Hohhot section of Dahei River from 2013 to 2022,the water quality of Dahei River was comprehensively analyzed and evaluated by single factor evaluation method,comprehensive pollution index method and Spearman rank correlation coefficient method,which provided technical support for comprehensively grasping the changing trend of water environment quality of Dahei River.It is found that the water pollution situation of Dahei River has changed significantly in recent ten years,and the water environment quality has improved obviously.
