AB  - In order to study the temporal and spatial distribution characteristics of 
      atmospheric pollutants in cities (districts and counties) in the 
      Chengdu-Chongqing Twin-city Economic Circle (CCEC) and to provide a theoretical 
      basis for atmospheric pollution prevention and control, this paper combined 
      Ambient Air Quality Standards (AAQS) and WHO Global Air Quality Guidelines (GAQG) 
      to evaluate atmospheric pollution and used spatial correlation to determine key 
      pollution areas. The results showed that the distribution of atmospheric 
      pollutants in CCEC presents a certain law, which was consistent with the air 
      pollution transmission channels. Except for particulate matter with an 
      aerodynamic diameter equal to or less than 2.5 mum (PM(2.5)) and ozone (O(3)), 
      other pollutants reached Grade II of AAQS in 2020, among which particulate matter 
      with an aerodynamic diameter equal to or less than 10 mum (PM(10)), PM(2.5), 
      sulfur dioxide (SO(2)), nitrogen dioxide (NO(2)) and carbon monoxide (CO) have 
      improved. Compared with the air quality guidelines given in the GAQG, PM(10), 
      PM(2.5), NO(2) and O(3) have certain effects on human health. The spatial 
      aggregation of PM(10) and PM(2.5) decreased year by year, while the spatial 
      aggregation of O(3) increased with the change in time, and the distribution of 
      NO(2) pollution had no obvious aggregation. Comprehensive analysis showed that 
      the pollution problems of particulate matter, NO(2) and O(3) in CCEC need to be 
      further controlled.
