| 摘要: |
| 在机动车数据的基础上,利用SMOKE模式估算了华南地区在路机动车污染物排放量,得到了用于空气质量数值模拟的网格化机动车排放源数据。估算结果显示机动车排放源主要分布在珠江三角洲和华南沿海地区,其中珠江三角洲排放量最大,且在深圳香港、广州、珠海澳门三个中心城市区分别出现了三个机动车排放中心,这三个中心与区域经济发达程度有较好的对应。分析还表明,快速增长的摩托车和小汽车数量对机动车排放总量的影响很大,是造成华南城市空气质量恶化的重要因素。 |

| Abstract: |
| Based on vehicle data,emission processing model SMOKE was used to calculate on-road vehicle emissions over the region of southern China,and thus gridded vehicle emissions for air quality modeling were obtained. The results indicated that large mobile emissions concentrated in the Pearl River Delta (PRD) region and along the coast of southern China. The maximum emissions occurred in the PRD with three major emission centers formed in three major urbanized regions such as Shenzhen-Hongkong,Guangzhou and Zhuhai-Macao respectively. These distributions of vehicle emissions were closely related to the status of economic development. Results also reveal that the rapid increases in the total numbers of motorcycle and light duty gasoline vehicle have great impact on mobile emissions,which could lead to remarkable deterioration of air quality in the metropolitan areas over southern China. |
