本文模拟了2000 - 2004年春季东亚地区人为排放和生物质燃烧排放的黑碳气溶胶的分布、输送和辐射效应。结果表明，全球存在三个主要的气柱负荷区：印度半岛、中南半岛和华东地区，这三个地区的气柱负荷均超过1 mg·m-2。印度半岛的污染物可以输送到中国，并影响中国大陆25°N ~ 30°N的纬向区域。中南半岛半岛的排放对中国大陆25°N以南地区的冷负荷有贡献。中南半岛黑碳（BC）水平通量的最大值出现在850-700 hPa之间。来自华北和东北地区的BC由于受东部急流的影响，可污染朝鲜半岛和日本。中国大陆输入通量大于输出通量，由于其他国家的排放，对中国大陆的影响对西部和华南的影响比对华北的影响更大。在晴天和阴天，BC气溶胶都增加了大气顶部向下的净辐射通量，而地面则相反。在中国四川盆地和湖北地区，TOA通量增加4 W·m-2，地面通量增加-55W·m-2。
The distribution transportation and radiative effects of black carbon aerosol due to anthropogenic and biomass burning emission over the East Asia region have been simulated in springtime from 2000 to 2004. It has been revealed that there exist three main column burden regions: Indian Peninsula, Indo-China Peninsula and East China, the column burden over the three regions exceeds 1 mg·m -2. Pollutant from Indian Peninsula can be transported into China, and affects the zonal region between 25°N and 30°N in Chinese mainland. Emission from Indo-China Peninsula can contribute to colume burden to the south of 25°N over Chinese mainland. The maximum horizontal flux of Black Carbon (BC) from Indo-China Peninsula emerges between 850-700 hPa. BC from North China and Northeast China can pollute Korea Peninsula and Japan due to eastern jet. Input flux is larger than output flux over China mainland, and it has more obvious effect on West China and South China than North China due to emission from other counries to China. The net downward radiative flux at Top of Atmosphere (TOA) has been increased by BC aerosol in both clear and cloudy sky, but that at the surface is opposite. The increament value emerges over Chinese Sichuan basin and Hubei area, 4 W·m -2 to TOA flux and -5 5 W·m -2 to surface flux.
