本报告重点分析黄河流域水污染和大气污染的治理情况。我国从“十一五”开始加大对黄河中上游的水污染防治力度，2006～2020年，黄河流域水质整体呈逐步改善趋势，总体水质由中度污染改善为轻度污染。黄河流域大气污染治理取得了一定成效，但多数城市可吸入颗粒物污染程度仍较高，难以达到国家空气质量二级标准，颗粒物扬尘污染仍不容忽视。“十四五”期间我国应统筹规划，加强水污染和大气污染综合治理，为实现生态环境根本好转作出贡献。
<<This report focuses on the treatment of water pollution and air pollution in the Yellow River Basin. Since the “11th Five-Year Plan”，China has intensified the prevention and control of water pollution in the middle and upper reaches of the Yellow River. From 2006 to 2020，the water quality of the Yellow River Basin has shown a gradual improvement trend，and the overall water quality has improved from moderate pollution to light pollution. Air pollution control in the Yellow River basin has also made some achievements，but the level of inhalable particulate matter pollution in most cities is still high，and it is difficult to meet the national air quality standard ii. Particulate dust pollution still cannot be ignored. During the “14th Five-Year Plan” period，we should make overall plans to strengthen the comprehensive treatment of water and air pollution and make contributions to the fundamental improvement of the ecological environment.
