本文旨在研究位于中国北方的京津冀（BTH）地区的汽车排放趋势。1999-2010年期间道路车辆NOx、CO、VOC和PM10的多年排放清单是通过COPERT IV模型开发的。结果表明：研究区车辆CO和VOC排放量的年平均变化率（AACR）分别为-3.1% ~ -5.2%和-4.4% ~ -6.9%。然而，由于货运的快速发展，天津和河北地区NOx和PM10的排放量不断增加。基于车辆排放清单，评估了不同标准车辆排放水平的趋势，以及实施车辆排放减缓战略的总体效果。建议逐步淘汰排放水平较高的欧零和欧一乘用车。尽管PC人口的排放增长率（IR）低于PC人口，但近年来PC人口的急剧增长导致了排放量的显著增加，削弱了整体的减缓效果。中国应研究车辆总容量和其他缓解措施，以制定新的和更有效的车辆排放控制战略。(C) 2012 Elsevier Ltd.版权所有。
This paper aims to study the vehicular emissions trends in the Beijing-Tianjin-Hebei (BTH) region, located in northern China. The multiyear emission inventories of NOx, CO, VOC and PM10 from road vehicles in the period 1999-2010 were developed by the COPERT IV model. Results show that vehicular emissions of CO and VOC have decreased by annual average change rates (AACR) of -3.1% to -5.2% and -4.4% to -6.9% in the study area, respectively. However, due to the rapid development of freight traffic, emissions of NOx and PM10 have kept increasing in Tianjin and Hebei. Based on the vehicular emission inventories, trends of emission levels for vehicles with different standards, as well as the overall effects of implementing vehicular emission mitigation strategies were assessed. It is suggested that passenger cars (PC) with Euro 0 and Euro I standards, which were at higher emission level in the PC fleet, should be gradually eliminated. Although the increasing rates (IR) of emissions from PC were lower than those of the PC population, the sharp growth of PC population in recent years contributed to a remarkable increase of emissions, weakening the overall mitigation effect. Total vehicle population capacity and other mitigation measures should be studied in China in order to develop new and more effective vehicular emission control strategies. (C) 2012 Elsevier Ltd.
