Abstract To evaluate the effects of the implementation of emission reduction measures and the revolution of air quality during the 70th anniversary of victory parade in Beijing, the variation of characteristics of air pollutant was analyzed based on observations of air pollutants at twelve sites in Beijing City from August 1, 2015 to September 18, 2015, and compared with that in 2014. The results showed that: The average concentrations of PM2.5, SO2, NO2, CO were 17.05μg/m3, 2.35μg/m3, 21.04μg/m3, 0.56mg/m3 respectively during emission reduction, the average concentrations of PM2.5, SO2, NO2, CO were decreased by 71.26%, 36.49%, 37.92%, 37.78% compared to the period before emission reduction, after the emission reduction, with the cancellation of emission abatement measures, air pollutant showed an upward tendency. Compared with the same time in 2014, the average concentrations of PM2.5, SO2, NO2, CO were decreased by 73.59%, 56.64%, 52.39%, 38.46% during emission reduction, air quality improvement was very obvious. Diurnal variation of pollutants were similar, the same time in 2014> during emission reduction> day of the event. The concentrations of pollutants was well below the same time in 2014 at each monitoring site during emission reduction, the improvement percentage of PM2.5 was big and the spatial difference was relatively small, the spatial difference of SO2 was zhengyf@nuist.edu.cnmost obvious, the concentrations of PM2.5 at different sites were decreased by 68.91%~77.63%, the concentrations of SO2 at different sites were decreased by 7.43%~74.75%, the concentrations of NO2 at different sites were decreased by 34.60%~72.28%, the concentrations of CO at different sites were decreased by 24.98%~63.73%. The average concentrations of PM2.5, SO2, NO2, CO in Beijing was lower than nearly surrounding areas, this further shows that implementation measures had made a great contribution to the improvement of air quality in Beijing during emission reduction.
