中文摘要：
人类活动向大气中排放气溶胶,人为气溶胶增强了对太阳辐射吸收和散射直接改变地气系统的辐射平衡,又可以通过作为云凝结核或冰核改变云的微物理特性和停留时间、地表反照率等途径间接影响气候的辐射强迫。综合以往研究,文章主要总结了2种影响气候辐射强迫性质相反的黑碳气溶胶和硫酸盐气溶胶以及相对湿度和黑碳的混合状态对气溶胶辐射强迫效应的影响。完善对大气气溶胶,尤其是人类活动产生的气溶胶的气候强迫机制及对地气系统影响的认识。
英文摘要：
Anthropogenic aerosols in atmosphere that release from anthropogenic activities enhance absorption and scattering to solar radiation, which could change the radiation balance of earth-atmosphere system directly and also act as cloud condensation nuclei or ice nucleus then influence on the radiative forcing by changing the microphysical property,duration of stay, land surface albedo of cloud and so on. Based on previous research findings,this article summarizes mainly two kinds of radiative forcing with opposite natures, which will affect the climate, black carbon aerosol and sulfate aerosol, and clarifies the impact that relative humidity, mixed state of black carbon have on the radiative forcing effect of aerosol. Above all, it improves the knowledge of atmospheric aerosol, especially the climate forcing effect of anthropogenic aerosols and influence on earth-atmosphere system.
