| 英文摘要 | The beijing government and its surrounding provinces implemented a series of measures to ensure haze-free skies during the 22nd asia-pacific economic cooperation (apec) conference (november 10th-11th, 2014). these measures included restrictions on traffic, construction, and industrial activity. twelve hour measurements of the concentration and composition of ambient fine particulate matter (pm2.5) were performed for 5 consecutive months near the apec conference site before (september 11th-november 2nd, 2014), during (november 3rd-12th, 2014) and after (november 13th, 2014-january 31st, 2015). the measurements are used in a positive matrix factorization model to determine the contributions from seven sources of pm2.5: secondary aerosols, traffic exhaust, industrial emission, road dust, soil dust, biomass burning and residual oil combustion. the source apportionment results are integrated with backward trajectory analysis using weather research and forecast (wrf) meteorological simulations, which determine the relative influence of new regulation and meteorology upon improved air quality during the apec conference. data show that controls are very effective, but meteorology must be taken into account to determine the actual influence-of the controls on pollution reduction. the industry source control is the most effective for reducing concentrations, followed by secondary aerosol and biomass controls, while the least effective control is for the residual oil combustion source. the largest reductions in concentrations occur when air mass transport is from the west-northwest (ulanqab). secondary aerosol and traffic exhaust reductions are most significant for air mass transport from the north-northwest (xilingele league) origin, and least significant for northeast transport (chifeng via tangshan conditions). the largest reductions of soil dust, biomass burning, and industrial source are distinctly seen for ulanqab conditions and least distinct for xilingele league.
