| 中文摘要 |
| 本文首先明确了汽车道路污染分担率和汽车区域污染分担率两个不同的概念,介绍了汽车区域污染分担率的计算方法。计算结果表明北京市三环内汽车区域污染分担率冬季CO为14.3%,NOx为32.2%,THC为46.0%,秋季CO为58.4%,NOx为68.7%,THC为86.6%。北京市汽车道路污染分担率(路中)冬季CO为65.7%,NOx为71.6%,THC为37.6%;秋季CO为58.8%,NOx为75.5%,THC为67.5%。 |
| 英文摘要 |
| This paper clearly defines the conceptions for both road and regional pollution contributions and gives a set of methods for the calculation of regional pollution contribution. As an example, the pollution contributions of CO, NOx, and THC, which are major pollutants from vehicles, were studied for an central area of 158 km2 of Beijing city. The study shows that the regional pollution contributions for CO, NOx and THC reached 14.3%, 32.2% and 86.6% in winter and 58.4%, 68.7%, and 86.6% in fall, respectively. While, the road pollution contributions for CO, NOx and THC reached 65.7%, 71.6%, and 37.6% in winter and 58.8%, 75.5% and 67.5% in fall, respectively. |
