摘要
近年来,我国大气污染格局发生了深刻变化,PM2.5与臭氧(O3)成为影响我国城市和区域空气质量的主要空气污染物,二者协同控制已成为我国空气质量改善的焦点和打赢蓝天保卫战的关键.PM2.5与臭氧之间具有复杂的关联性,使得二者的协同控制具有复杂性与艰巨性.分析了PM2.5与臭氧成因的关联性及其相互影响,阐明了PM2.5与臭氧污染协同控制所涉及的重要科学问题,并在此基础上研究了目前我国PM2.5与臭氧的污染形势及二者的关联性,梳理了我国自2013年以来在PM2.5与臭氧污染控制中已采取的重要举措,论述了目前我国PM2.5与臭氧协同控制在科学与管理上所面临的挑战.结合对国外成功经验的分析,提出推进我国PM2.5与臭氧污染协同控制工作的相关建议:①加快监测能力建设,完善管理体系;②强化科技支撑,提高PM2.5与臭氧污染控制精准性;③加快构建VOCs与NOx治理技术体系;④加大VOCs与NOx的协同减排力度,保障减排方案落实到位.
The pattern of air pollution in China has undergone profound changes in recent years,which is the most apparent in the fact that both PM2.5 and ozone are main atmospheric pollutants affecting air quality in urban and regional areas of China.As a result,the coordinated control of PM2.5 and ozone has become the focus of improving air quality and the key to winning the battle of the three-year plan on defending the blue sky in China.However,the complicated coupling relationship between PM2.5 and ozone increases the complexity and difficulty of the coordinated control.Therefore,the correlation between the formation mechanisms of PM2.5 and ozone,and their interactions were analyzed,and the important scientific issues involved in the coordinated control of PM2.5 and ozone were clarified.Based on the above analysis,the pollution situation of PM2.5 and ozone in China and the correlation between them were investigated,the important countermeasures that China had taken in PM2.5 and ozone pollution control since 2013 were reviewed,and the scientific and managerial challenges of the coordinated control of PM2.5 and ozone in China was discussed.Finally,considering the successful experience of foreign countries in coordinated-controlling of PM2.5 and ozone,some suggestions for pushing the coordinated control of PM2.5 and ozone in China were put forward.(1) The construction of monitoring capacity should be accelerated,and the comprehensiveness of the management system should be improved;(2) Technology support should be strengthened to improve the accuracy for controlling PM2.5 and ozone pollution;(3) The establishment for the technical system for controlling VOCs and NOx should be accelerated;(4) The coordinated reduction of VOCs and NOx emissions should be amplified to ensure the success in implementing the mitigation countermeasures.
