我国大气污染协同防控理论框架初探

我国大气污染防治工作在“十三五”期间取得了可喜成绩，PM_2.5浓度及重污染天数大幅降低，与此同时，我国城市地区臭氧(O₃)污染问题凸显，说明我国大气污染格局发生了深刻变化. 当前，PM_2.5与O₃成为影响我国城市和区域空气质量的主要因子，二者的协同控制是我国持续改善空气质量的焦点，也成为我国“十四五”期间大气污染防治工作的重点. 本文通过对国内外PM_2.5和O₃协同控制进展的梳理，总结我国大气复合污染协同治理的现状与挑战，从协同防控目标、核心协同任务、重点支撑保障等角度提出大气复合污染协同治理的理论框架，并对我国PM_2.5与O₃协同控制工作提出以下几点建议:①坚持科学精准治气；②坚持综合系统治气；③坚持严格依法治气；④坚持多维协同治气. 

Preliminary Research on Theoretical Framework of Cooperative Control of Air Pollution in China

During the ‘13th Five-Year Plan’ period, China has made promising achievements in air pollution prevention and control. The concentration of PM_2.5 and the number of heavily pollution days have decreased significantly. At the same time, O₃ pollution in urban areas has become a prominent problem, indicating that China's air pollution has undergone profound changes. In recent years, PM_2.5 and O₃ have gradually become the main factors that affect the continuous improvement of air quality in urban and regional areas in China. The so-called complex air pollution of PM_2.5 and O₃ will be the focused issue of air pollution prevention and control strategy in China and the synergistic control of multiple air pollutants will become the major task during the ‘14th Five-Year Plan’ period. Through combing the progress of synergistic control of the pollutants of PM_2.5 and O₃ in China and abroad, this paper summarizes the current situation and challenges of the synergistic control of PM_2.5 and O₃ pollution all over China. We propose a preliminary theoretical framework for collaborative control of air pollution, which includes the objectives of collaborative prevention and control, major tasks and key supporting conditions. In conclusion, we put forward some relevant suggestions for the collaborative control of PM_2.5 and O₃ pollution: (1) Insist on scientific and precise strategy of air quality. (2) Insist on comprehensive and systematic strategy of air quality. (3) Insist on strict strategy of air quality according to the law. (4) Insist on multi-dimensional coordinated strategy.
