摘　　要：利用包头市生态环境监测网的数据,分析了2016—2023年包头市空气和地表水环境质量状况,并对2025年的生态环境质量变化特征和趋势进行预测。结果表明,2016—2023年期间,包头市生态环境质量状况持续向好。预测2025年,包头市环境空气质量除O_(3)外,SO_(2)、NO_(2)、CO、PM_(10)和PM_(2.5)浓度明显下降;地表水主要污染物NH3-N、F-、P和BOD5浓度不断下降,东河、西河消除劣Ⅴ类水体。总体来看,包头市生态环境质量呈现稳中向好趋势。但也存在环境空气季节性污染问题突出,水生态环境先天不足等问题,需要采取科学措施,巩固取得的成效。Based on the data from Baotou′s ecological environment monitoring network,the air and surface water environmental quality conditions of Baotou City from 2016 to 2023 were analyzed,and the characteristics and trends of ecological environment quality changes in 2025 were predicted.The results show that during the period from 2016 to 2023,the ecological environment quality of Baotou City has been continuously improving.It is predicted that in 2025,the concentrations of sulfur dioxide,nitrogen dioxide,carbon monoxide,inhalable particulate matter and fine particulate matter in the air of Baotou City will significantly decrease,except for ozone;the concentrations of ammonia nitrogen,fluoride,total phosphorus and fiveday biochemical oxygen demand in surface water will continue to decline,and the East River and West River will eliminate water bodies of inferior Class V.Overall,the ecological environment quality of Baotou City shows a stable and improving trend.However,there are still prominent seasonal air pollution problems and inherent deficiencies in water ecological environment,which require scientific measures to consolidate the achieved results.
