气候协同的区域空气质量精细化调控战略研究
Strategical Research on Refined Regulations for Regional Air Quality with Climate Synergy
开展气候协同的区域空气质量精细化调控研究，对推进我国空气质量持续改善、构建未来气候背景下多污染物协同减排路径、实现绿色可持续发展具有重大战略意义。本文分析了区域大气污染演变规律、多污染物相互作用机制、污染防治策略与控制技术成效，完成了多视角剖析与多技术相互印证的集成研究，阐明了多污染物非线性响应关系，并梳理形成了区域精细化调控技术体系；在探讨气候变化与大气污染相互影响的基础上，提炼了空气质量精细化调控技术路线，提出了中长期空气质量改善策略和路线图。研究建议，针对当前的大气复合污染特征，PM2.5与O3协同控制的核心在于大气氧化性调控，需要持续强化一次污染物减排，同时因时因地并结合气候气象条件开展VOCs和NOx协同的精细化减排；发挥“双碳”政策的推动作用，通过四大结构调整和低碳转型，实现多类型污染物的协同深度减排，达到PM2.5与O3浓度的同步下降。
Strategical research on the refined regulations for regional air quality with climate synergy is essential for continuously improving the air quality, creating a coordinated multi-pollutants reduction path, and promoting sustainable development in China.This study analyzed the evolution characteristics of regional air pollution, the multi-pollutant interaction mechanisms, and the effectiveness of air pollution prevention and control strategies and technologies. Multi-perspective analysis and integrated research were conducted to clarify the non-linear relationship among multiple pollutants and formulate a technology system for refined regional regulation. The interaction between climate change and air pollution was explored as well. By summarizing the current technical routes for air pollution and control, the medium- and long-term air quality improvement strategies and roadmaps were proposed. Considering the current situation of air pollution in China, the regulation on atmospheric oxidation is the core for the coordinated control of PM2.5 and O3 pollution. Therefore, it is necessary to continuously promote emission reduction of primary pollutants and conduct refined and coordinated reduction of VOCs and NOx emissions considering specific climate and meteorological conditions. Additionally, coordinated emission reduction of multiple types of pollutants can be realized through adjustment of energy,transportation, industry, and landuse structures as well as low-carbon transformation, thereby synchronously reducing the PM2.5 and O3 concentrations.
