英文摘要	To examine the effect of pollution control measures on beijing air quality during the 2008 olympic games, this paper analyzes the variation of aerosol extinction coefficient observed with a dual-wavelength polarized lidar in beijing during the olympic games. the results show that (1) during the beijing olympic games, the aerosol extinction coefficient decreased to about 42.3% in the surface layer (below 250 m) compared with that in 2007 under almost the same meteorological conditions, indicating the effectiveness of local air pollution control measures in beijing areas; (2) the analysis of the aerosol extinction coefficient obtained before (jul. 20-aug. 7, 2008) and during the beijing olympic games (aug. 8-aug. 24, 2008) shows a maximum decrease of daily aerosol extinction coefficient in layer of 0.5-1.5 km. to elucidate such a phenomenon, the transport of pm10 from surrounding areas to beijing was simulated by naqpms (the nested air quality prediction modeling system) during jul. 20 to aug. 24, 2008. analysis of pm10 transport from neighboring areas indicated a decrease of 36.6% during the olympic games. this demonstrated the efficiency of pollution control measures in surrounding areas in improving air quality in beijing.
