基　　金：supported by the National Basic Research Program of China(2010CB951803);the China Sustainable Energy Program(G-1010-12447);the Project of Monitoring and Management on Emission Reduction,managed by the Ministry of Environmental Protection of China.(2011A078) 摘　　要：Satellite derived NO2 column data have been used to study Chinese national fossil fuel consumption and pollutant emissions.Based on NO 2 retrievals from two satellites (GOME and SCIAMACHY) for 1996-2010,we analyzed the characteristics and evolution of regional pollution related to NO x emissions in China.Satellite observations indicated that the highly polluted regions were expanding.Anthropogenic emission dominated areas have expanded from the east to central and western China,and new highly polluted regions have formed throughout the nation.Bottom-up emission estimates suggested a 133% increase in anthropogenic NOx emissions in East Central China during 1996 to 2010,which was lower than the 184% increase of the NO2 columns measured by the satellites.We found that growth rates of NOx emissions have slowed in Chinese megacities over recent years,in contrast to which,the NOx emissions were soaring in medium-sized cities,indicating that strict controls of NOx emissions from coal-fired facilities are required in China. 关键词：氮氧化物排放量卫星遥感中国污染物排放 NO2 燃料消耗卫星反演区域污染
