摘　　要： 准确界定了气溶胶含碳物质,特别是有机碳和元素碳的基本概念,指出了元素碳与黑碳的异同,总结了有机碳和元素碳的排放源,以及二次有机碳的经验公式。阐述了有机碳、元素碳对全球气候、大气化学过程及人体健康带来的危害及机理。归纳了气溶胶中有机碳、元素碳组分的空间分布特征、时间变化特征。概述了国内气溶胶有机碳、元素碳的研究状况,指出国内相关研究重点和趋势。 Based on the researches of carbonaceous aerosol, clear conception of the carbonaceous especially, that of organic carbon （OC） and elemental carbon （EC） was offered, and the difference between EC and black carbon （BC） was recognized ; the main sources of OC and EC were summarized, and the model of quantification of second OC was given; the influences of carbonaceous on global climate, atmospheric chemistry process and human health were indicated ; spatial distribution and temporal variation of carbonaceous were reviewed. Research progress of OC and EC in China were summarized and research trend were prospected.
