This research has been achieved in order to quantify the long-term trend of the air quality in Beijing, China where the outstanding and historic development has undergone in the past 10 years at the beginning of the 21^<st> century. The average aerosol concentration in Beijing was approximately five times higher than those observed in several other cities in the world. The air quality in Beijing has not been improved during the past 10 years in terms of the aerosol pollution. Many regulations that have been applied to prevent the air quality in Beijing from the air pollution during the Olympic Games 2008 made the larger aerosols that have the particle size larger than 2.5μm reduced 25%, however it didn't work well for the reduction of much smaller aerosols that have the particle size smaller than 2.5μm.

本研究的目的是为了量化21^世纪初北京市空气质量的长期变化趋势，北京市在过去的10年里取得了显著的历史性发展<st>。北京的平均气溶胶浓度大约是世界上其他几个城市观测到的浓度的五倍。近10年来，北京市空气质量在气溶胶污染方面没有得到改善。2008年北京奥运会期间，北京市针对大气污染采取了多项措施，使大于2.5μm的大颗粒气溶胶减少了25%，但对小于2.5μm的小颗粒气溶胶的减少效果并不理想。
