【PM2.5与臭氧协同控制专题】编者按：当前，PM2.5和臭氧已经成为影响我国环境空气质量的主要污染物. 2021年3月，第十三届全国人民代表大会第四次会议批准了《中华人民共和国国民经济和社会发展第十四个五年规划和2035年远景目标纲要》，该纲要明确提出要加强城市大气质量达标管理，推进PM2.5和臭氧协同控制，地级及以上城市PM2.5浓度下降10%，有效遏制臭氧浓度增长趋势，基本消除重污染天气. 2021年11月，中共中央、国务院印发《关于深入打好污染防治攻坚战的意见》，明确要求到2025年，臭氧浓度增长趋势得到有效遏制，实现PM2.5和臭氧协同控制. PM2.5和臭氧的协同控制，成为我国“十四五”及更长时期大气污染防治的一项重要任务. 近期，各有关方面围绕PM2.5与臭氧协同控制开展了大量工作，并取得了一定的成果. 有鉴于此，本刊特开设“PM2.5与臭氧协同控制”专栏，经严格的同行评议后，共刊发11篇文章，内容涵盖PM2.5与臭氧的污染特征、相互关系、成因分析、防控理论等方面，以期能引起学界的进一步思考与探讨.

摘要: 我国大气污染防治工作在“十三五”期间取得了可喜成绩，PM2.5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，PM2.5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PM2.5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PM2.5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.Abstract: During the ‘13th Five-Year Plan’ period, China has made promising achievements in air pollution prevention and control. The concentration of PM2.5 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, PM2.5 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 PM2.5 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 PM2.5 and O3 in China and abroad, this paper summarizes the current situation and challenges of the synergistic control of PM2.5 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 PM2.5 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.
