Abstract: Sulfur dioxide (SO 2 ), nitrogen dioxide (NO 2 ), and ozone (O 3 ) are important atmospheric pollutants that affect air quality. The long-term variations of SO 2 and NO 2 in 2008–2018 and O 3 in 2015–2018 in the relatively less populated ecological and economic zones of Western Sichuan Plateau, Southwest China were analyzed. In 2008–2018, the variations in SO 2 and NO 2 in the ecological zone were not significant, but Ganzi showed a slight upward trend. SO 2 decreased significantly in the economic zone, especially in Panzhihua, where NO 2 changes were not obvious. From 2015 to 2018, the concentration of O 3 in the ecological zone increased significantly, while the economic zone showed a downward trend. The rising trend of the concentration ratio of SO 2 to NO 2 in the ecological zone and the declining trend in the economic zone indicate that the energy consumption structure of these two zones is quite different. The lower correlation coefficients between NO 2 and O 3 in the Western Sichuan Plateau imply that the variations of O 3 are mainly affected by the regional background. The effects of meteorological factors on SO 2 , NO 2 , and O 3 were more obvious in the economic zone where there are high anthropometric emissions.
