Abstract:

Different emission inventories were applied to investigate the spatial distribution and temporal variation of anthropogenic emission in China during the period from 2000 to 2010. The analysis results indicate that the total anthropogenic emission generally increased during the past 10 years. NOx emission increased continuouslly and it exceeded SO2 emission in 2010. From 2006 to 2010, PM10 and SO2 emissions decreased by 76% and 10%, respectively. From 2000 to 2010, the emissions of SO2, NOx, and BC increased by 5.6 Tg (25%), 13.1 Tg (85%), and 0.3 Tg (20%), respectively, but OC emission decreased by about 0.7 Tg (17%), PM10 emission largely decreased by 12.4 Tg (74%), and there was no obvious change in NMVOC emission. There are quite large differences in the temporal variations of emissions among different regions of China.
