摘　　要：为了更好地了解我国区域碳气溶胶,利用意大利国际理论物理中心ICTP(International Center forTheoretical Physics)的气溶胶资料和区域气候模式R egCM 3对2000年我国碳气溶胶时空分布与辐射强迫进行了数值模拟。结果表明:我国碳气溶胶主要分布在黄河以南、青藏高原以东的广大区域,且柱含量分布具有明显的季节性。春季最大,冬季次之,夏季最小;除东部沿海等少数地区外,碳气溶胶大气顶辐射强迫在全国绝大部分地区符号均为正,而地表辐射强迫符号为负。各单种气溶胶之间存在复杂的相互作用,研究综合气溶胶分布和气候效应时,不能简单地将各单种气溶胶的作用进行叠加。To enhance understanding on the carbonaceous aerosols over China,aerosol data from International Center for Theoretical Physics（ICTP） and regional climate model RegCM3 were used to simulate the temporal and spatial distribution and radiative forcing of the carbonaceous aerosols in 2000.The preliminary results show that carbonaceous aerosols are mostly concentrated in the area of the south of Yellow River and the east of Tibetan Plateau.Referring to the seasonal variation characteristics,the simulation indicates that the maximum value of column burden of the carbonaceous aerosols appears in spring,the second value in winter and the minimum in summer.The radiative forcing of the carbonaceous aerosols is positive on the top of atmosphere（TOA） besides eastern littoral and negative on the ground.The complex mutual action exists in different kinds of aerosols,which indicates that experiments on the distribution and climate effects of aerosols should not add the effects of single aerosols.
