摘　　要：空气污染物排放清单是影响数值模式结果准确性的关键因子之一.定义不同排放清单中同一污染物排放量最大值与最小值之差与平均值的比值为差异度,对比分析了4个国内外广泛应用的人为污染源排放清单(TRACE-P、INTEX-B、REAS1.1和REAS2.0).结果表明:INTEX-B、REAS1.1和REAS2.0清单中给出的2006—2007年我国(不包括港澳台地区数据)SO2排放量差异度为12%,而在SO2排放量较大的省份(如山东、河北和河南等)差异度达30%以上;NOx和NMVOC(非甲烷挥发性有机物)的排放量差异度分别为51%和30%,在山东、江苏、浙江、北京和上海等经济较发达地区的差异度达到20%～80%.相对于2000年的排放清单,2006—2007年排放清单各污染物的排放量增长明显,SO2、NOx和NMVOC的排放量在INTEX-B、REAS1.1和REAS2.0清单中的平均值分别为TRACE-P清单的1.6、1.9和1.5倍.近年来经济的高速发展、能源消耗的增长和空气污染控制技术的应用等都会影响人为活动水平和排放因子的选取,这也是造成排放清单间存在差异的主要原因.Recently, China is facing serious regional combined air pollution. Numerical models are applied both in policymaking and scientific research, and the emission inventories are crucial to the accuracy of the simulation. The differences of air pollutants over China in four independent Asian regional anthropogenic emissions inventories and their potential impacts of Chinese pollutants long-transport were analyzed. The four inventories included, I . a regional inventory used in Transport and Chemical Evolution over the Pacific （TRACE-P） ; II. a regional inventory used in Intercontinental Chemical Transport Experiment-Phase B （INTEX-B） ;llI. regional emission inventory in Asia Version 1.1 ; and IV. regional emission inventory in Asia Version 2. O. The resuhs revealed significant differences in the emission estimations on sulfur dioxide （SO2 ） emissions in the provinces emitting most pollutants in 2006-2007 （e. g. Shandong, Hubei and Henan）, although the national amounts of China were already closed. The national averaged differences of nitrogen oxides （ NO, ） and non-methane volatile organic compounds （NMVOC） emission estimates in the four inventories were 51% and 30% , respectively, which reached up to 80% in China＇ s developed regions （e. g. Shandong, Jiangsu, Zhejiang, Beijing and Shanghai）. Emissions of most pollutants in other three inventories （2006-2007） were higher, compared with TRACE-P inventory （2000）. The average emissions of SO~, NO~, and NMVOC （in 1NTEX-B, REAS1. 1 and REAS2.0） were 1.6, 1.9, and 1.5 times of the emissions in TRACE-P inventory, respectively. These z＇~erenees probably caused by the treatment in changes of activity rates and emission factors in China due to economic development and application of rapid technology renewal.
