摘　　要： 二次有机气溶胶由于其对环境、气候和人体健康的影响,正日益受到人们的关注。我国地域辽阔,森林占国土面积的12%,几乎具有北半球的全部植被类型,对天然源二次有机气溶胶的研究不容忽视。综合当前的研究成果,着重阐述了两种代表性生物挥发性有机化合物,异戊二烯和α-蒎烯与大气中主要的氧化剂,如O3、OH和NO3等物种的反应,以及其二次气溶胶形成的过程。最后,对目前的研究手段和未来的研究方向进行了探讨。 Secondary organic aerosols have been captured more and more attention, due to their impact on environmental, climate and health. China has a vast land, with 12% of the surface covered by forest, and has almost all kinds of characteristic plant species of the Northern Hemisphere. Therefore, one cannot ignore the contribution of the biogenic volatile organic compounds to the secondary organic aerosols. This review focuses on the reaction of isoprene and α-pinene with atmospheric oxidants, such as 03, OH and NO3, and the subsequent formation of secondary particles via gas-to-particle conversion. The present research techniques and future research directions are discussed.
