In order to study the characteristics of air pollution and evaluate the effects of air pollution emergency control measures in Shijiazhuang City on November 1stto 11th2014 APEC meeting,the air pollutants' concentrations and emission reduction amounts were comparatively studied. Three sites in different functional areas were chosen( Fenglongshan( FLS,background site),Renminhuitang( RMHT,downtown site) and Gaoxinqu( GXQ,industrial site)). Hourly average SO_2,NO_2,CO,O_3,PM_(2. 5) and PM_(10) concentrations were analyzed. The results show that air quality was better during APEC 2014 than during the same period in 2013,during which most of the pollutants( except ozone) were significantly decreased. ρ( SO_2),ρ( NO_2),ρ( CO),ρ( PM_(2. 5)) and ρ( PM_(10)) concentrations during APEC 2014 decreased by 55. 1%,22. 9%,16. 7%,36. 8% and 31. 0% at FLS,35. 5%,28. 0%,32. 6%,36. 9% and 56. 2% at RMHT,49. 4%,26. 6%,16. 5%,32. 9% and 53. 5% at GXQ,respectively,compared with those concentrations during the same period in 2013. Additionally,the major pollutants in different functional areas were also greatly changed,as a result of the air pollution emergency control measures. In the downtown area and industrial sites, the control of dust showed significant effects on the concentration of PM_(10). The control of high altitude emissions( e.g.,power plants) proved to be an effective way to lower the concentration of SO2 in the background area. Back trajectory analysis was used to study the air mass origination and furtherevaluate the air pollution/meteorological conditions based on the weather chart. Although the meteorological conditions during APEC 2014 were found to be worse than those of the same period in 2013,the air quality was significantly improved due to the control measures.
