2013年我国柴油车黑碳排放特征研究

Black Carbon Emissions from Diesel Vehicles of 2013 in China

柴油车黑碳排放的研究可以为改善大气质量、保护人体健康和积极应对气候变化提供帮助。利用保有量调查、各类柴油车黑碳排放因子和活动水平研究测算了2013年中国各类型柴油车黑碳排放量。研究表明,虽然重型货车的保有量只占柴油车总量的18.8%,其黑碳排放却占到了总排放量的61%;国Ⅰ及以前的黄标柴油车只占总保有量的27.1%,其黑碳排放量却占到了总排放量的70%以上。分区域的柴油车黑碳排放状况分析表明我国东部地区的黑碳排放量要高于中部和西部地区。

Study on black carbon emissions from diesel vehicles can help related authorities make decisions on how to improve air quality, protect human health and actively respond to climate change. The black carbon emissions of different kinds of diesel vehicles were estimated by the population survey, black carbon factors testing and activity level research. The results showed that, although the heavy duty diesel vehicles contributed only 18. 8% of the total diesel vehicles, the black carbon emissions were accounted for 61% of the total emissions; China I and before China I diesel vehicles contributed only 27. 1% of the total population, the black carbon emissions account for more than 70% of the black carbon emissions. Analysis of the black carbon emissions from different regions indicated that black carbon emissions in the eastern region of China was higher than those of the central and Western regions.
