| 摘 要： | 利用排放清单对2000—2010年中国地区人为排放源的时空分布特征进行分析.结果显示,10年来中国地区人为排放总体上是增加的.其中,NO x的排放量显示持续增加趋势,在2010年超过了SO2的排放;与2006年相比,2010年PM10排放量减少76%,SO2排放减少10%.与2000年相比,2010年SO2和NO x的排放量分别增加5.6 Tg(25%)和13.1 Tg(85%),BC增加0.3 Tg(20%),OC减少0.7 Tg(17%),PM10减少12.4 Tg(74%),而NMVOC变化不大.中国不同区域人为排放源的时间变化趋势差异较大.

| 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. |
