中国NO (x)排放量的快速增长主要是由于化石燃料的大量消耗。为了控制NO (x)排放，采用自下而上的方法建立了2000-2010年的多年NO (x)排放清单。结果表明，氮氧化物排放量从2000年的1181万吨增加到2010年的2433万吨，增长了2.1倍。对比2009年NO (x)的排放趋势，我们发现NO (x)的排放量已经超过了SO2的排放量。东、西部地区NO (x)排放不平衡的主要原因是区域生产总值和产业结构的差异。煤炭占中国能源消费总量的70%，是化石燃料中最大的NO (x)排放源。此外，柴油和汽油使用量的增加刺激了运输部门NO (x)排放量的增加。制造业、电力生产和交通运输合计约占全国NO (x)排放量的90%。与此同时，根据这一情景分析，到2020年，中国的能源消耗和氮氧化物排放预计分别为3908.5亿吨标准煤当量（SCE）和1970亿吨标准煤当量。为了实现理想的NO (x)减排目标，中国应该采取严格的措施控制NO (x)排放，如改进减排技术、颁布新的排放标准、各省联合控制等。
The rapid growth of NO (x) emissions in China is mainly due to intensive fossil fuel consumption. In order to control NO (x) emissions, a multiyear NO (x) emission inventory was established by a bottom-up approach for the period 2000-2010. The results showed that NOx emissions increased by 2.1 times from 11.81 million tons (Mt) in 2000 to 24.33 Mt in 2010. We found that NO (x) emissions had exceeded SO2 emissions in 2009 by comparison with their emission trends. We also found that the unbalanced NO (x) emissions in Eastern China and Western China are mainly due to the different gross regional product and industrial structure. Accounting for 70% of total energy consumption in China, coal is the largest NO (x) emission source among all the fossil fuels. In addition, the increased use of diesel and gasoline has spurred the increase of NO (x) emissions from the transportation sector. Manufacturing, electricity production, and transportation together composed about 90% of the national NO (x) emissions. Meanwhile, energy consumption and NO (x) emissions in China are predicted to be 3908.5 Mt standard coal equivalent (SCE) and 19.7 Mt in 2020 with this scenario analysis, respectively. To achieve a desired NO (x) reduction target, China should take strict measures to control NO (x) emissions, such as improvement in reduction technology, promulgation of new emission standards, and joint control by various Chinese provinces.
