植物释放挥发性有机物(VOCs)的研究进展

植物释放的有机物(VOCs)对大气圈臭氧的动态、一氧化碳的产生和甲烷的氧化起重要作用。本文主要综述了异戊二烯、单萜这两种重要的植物释放物,总结了国内外的研究进展,概括了它们的合成、释放以及环境因子的影响。同时简要介绍了其它几种植物释放的有机物,并就有机物的释放对大气化学、温室效应和全球变化的影响也作了简要分析。

Advances in the studies on plant production and emission of volatile organic conpounds

Volatile organic compounds (VOCs) that are produced by and emitted from plants play key roles in several aspects of tropo-spheric chemistry, including ozone dynamics, carbon monoxide production, and methane oxidation. Isoprene and monoterpene, the two most abundant and best studied VOCs, are introduced in this article. Isoprene emission is strongly dependent on light and temperature and has large variations in different species, while monoterpene emission is usually independent of light. Methanol and other compounds are also simply mentioned. We also analyze the relationship between the emission of VOCs and global change.
