中文摘要：

植物释放的挥发性有机物属于植物次生代谢物质,对环境和人类生存具有正反两方面的作用。一方面,它们具有杀菌抑菌、保健等功能;另一方面,它们还参与对流层大气化学过程,对全球气候变化、碳循环和人类健康等有潜在的负面影响。综述了植物挥发性有机物（BVOCs）的作用、影响BVOCs释放的因素及还有待扩展和深入研究的方面,并对今后的研究进行了展望。结果表明：1）植物挥发性有机物对环境和人类健康有正反两方面的作用,目前大部分研究集中于杀菌抑菌等正面效应,而针对植物VOCs的负面效应研究较少;2）影响植物VOCs释放的因素包括内部因素（树种差异、生理因素、N素）和外部因素（光照、温度、湿度、CO2、臭氧和胁迫）,目前研究多集中于单一因素;3）今后应加强植物VOCs释放机理的研究,分析其他因素或几种因素相互作用对植物释放VOCs的影响;建立和完善理论模型,用以模拟各种植物VOCs排放的时空动态,更好地预测全球气候变化。

英文摘要：

The author of this paper intends to offer a research review on the role and the influential factors of the biogenic volatile organic compounds（BVOCs）. As is often the case, volatile hydrocarbons emitted by the plants do have both positive and negative effects on the human bodies. On the one hand, it is even a common sense that the BVOCs are endowed with the likely antibacterial and health-promotion functions ; on the other hand, they tend to promote the changes in the chemical composition in the atmosphere via a series of redox reac- tions, which enables the compounds to play a significant role in con- stituting ozone, CO and so on. It is just for all the above said advan- tages of the biogenic volatile organic compounds that attract the atten- tion from the scholars to making unremitting efforts to explore their functions and influential factors. However, the efforts of this paper would be only oriented to the summary of commentary reviews and the influential factors of BVOCs emission, in addition to the aspects that are promising and worthwhile for the future in-depth exploration, though the positive effects such as antiseptic bacteriostasis, and even their negative effects may not be so attractive for the contemporary re- searches. What is more, such influential factors of BVOCs emission, as the species differences, physiological factors, N factor, and the environmental external factors such as light, temperature, humidity, C02, ozone and stress still remain indifferent for some researchers. Instead, the present studies would be concentrated on the single fac- tor. And, last of a11, we do think it necessary to strengthen the stud- ies on the release mechanism of BVOCs and the analysis of the inter- action of some factors or others that tend to influence on the emission of BVOCs. It is thus of great importance to launch a in-depth study to estimate how to affect the regional and even the global climate by changing the regional emission pattern of BVOCs. And, finally, ef- forts are also needed to establish a
