摘　　要：目的:分析2016-2023年成渝双城经济圈PM_(10)、PM_(2.5)、SO_(2)、NO_(2)、CO和O_(3)的时空变化特征,为该地区实施更有效的大气污染防治手段提供科学依据。方法:收集整理2016-2023年国控点监测数据,分析成渝双城经济圈6种污染物时空分布特征。结果:PM_(10)、PM_(2.5)、SO_(2)、NO_(2)和CO年际变化呈下降趋势,降幅分别为32.38%、31.15%、49.49%、22.58%和26.97%,O_(3)年季变化则具有波动性;PM_(10)、PM_(2.5)、NO_(2)和CO日浓度变化呈“双峰双谷”,峰值在09:00~11:00和22:00~23:00,谷值在05:00~06:00和16:00~18:00,SO_(2)日浓度峰值出现在11:00,谷值出现在19:00,O_(3)日浓度峰值出现在16:00,谷值出现在08:00;自贡市PM_(10)和PM_(2.5)浓度最高,泸州市SO_(2)浓度最高,达州市NO_(2)最高,达州市和重庆市CO浓度最高,资阳市O_(3)浓度最高。结论:本研究可为成渝双城经济圈制定和调整大气污染防治措施提供参考,且对该区域大气污染的持续改善具有重要的现实意义。Objective:To analyze the spatio-temporal variation of PM_(10),PM_(2.5),SO_(2),NO_(2),CO and O_(3)in Chengdu-Chongqing economic Circle,which can provide scientific basis for the implementation of more effective air pollution prevention and control measures.Methods:The national air quality monitoring sites data in Chengdu-Chongqing Economic Circle from 2016 to 2023 were collected,and the temporal and spatial distribution of six pollutants were analyzed.Results:The interannual changes of PM_(10),PM_(2.5),SO_(2),NO_(2)and CO in the Chengdu-Chongqing economic Circle showed a downward trend,with decreases of 32.38%、31.15%、49.49%、22.58%and 26.97%,respectively,while the interannual change of O_(3)showed a certain volatility;the daily concentrations of PM_(10),PM_(2.5),NO_(2)and CO show a“double peak and double valley”distribution,with peak values at 09:00~11:00 and 22:00~23:00,and trough values at 05:00~06:00 and 16:00~18:00.SO_(2)concentration peaks at 11:00,the valley value occurs at 19:00.O_(3)concentration peaks at 16:00,the valley value occurs at 08:00;the highest concentrations of PM_(10)and PM_(2.5)was Zigong City,the highest concentration of SO_(2)was Luzhou City,the highest concentrations of NO_(2)was Dazhou city,the highest concentrations of CO was Chongqing and Dazhou City,and the highest concentration of O_(3)was Ziyang City.Conclusion:This study could provide reference for the formulating and adjustment of air pollution prevention and control measures in Chengdu-Chongqing economic circle,which has important practical significance for the continuous improvement of air pollution.
