摘　　要：目前PM和臭氧污染是影响大气污染的主要因素,也是制约温江区环境空气质量持续改善的主要瓶颈。利用后向轨迹模型和CMAQ空气质量模型对温江区2021年典型污染过程进行分析,研究结果表明温江区局地气象特征明显,在典型污染过程中PM和臭氧浓度在本地污染源和外来传输源的叠加影响下易快速累积,且污染持续时间长。为持续改善环境空气质量,本文结合实际,提出温江区大气污染防治工作措施及建议。At present, PMand ozone pollution are the main factors affecting air pollution, and also the main bottleneck restricting the continuous improvement of environmental air quality in Wenjiang District. In this study, the backward trajectory model and CMAQ air quality model were used to analyze the typical pollution process in Wenjiang District in 2021. The results show that the local meteorological characteristics in Wenjiang District are obvious, and the PMand ozone concentration could accumulate rapidly under the superimposed influence of local pollution sources and external pollution sources, and the pollution lasts for a long time. In order to continuously improve the ambient air quality, the measures and suggestions of air pollution prevention and control in Wenjiang District are proposed according to the actual situation in this article.
