大气二氧化碳和臭氧浓度升高对植物挥发性有机化合物排放影响的研究进展

对流层大气中CO₂和O₃浓度变化可对植物挥发性有机化合物(VOCs)的排放产生一定影响,而植物VOCs具有很高的化学活性,可影响低层大气的化学组成,促进光化学污染的形成,对温室效应和全球变化具有潜在的影响.文中总结了大气CO₂和O₃浓度单独及复合作用对植物VOCs排放规律的影响,并对今后植物VOCs排放规律及多重环境胁迫下城市树木VOCs释放机制的研究进行了展望.

Research advances in the effects of elevated atmospheric carbon dioxide and ozone on biogenic VOCs emission

The increasing concentrations of CO_2 and O_3 in the troposphere have become a focus of both the domestic and foreign researchers,and the emissions of biogenic volatile organic compounds (BVOCs) can be affected by the change of concentrations.The BVOCs with high chemical reactivity may affect the chemical compositions of lower atmosphere,and promote photochemistry air pollution.At one time,the greenhouse effect and global environment changes will be influenced by the BVOCs.The effects of single and joint action of CO_2 and O_3 on the emitting characteristics of biogenic volatile organic compounds (BVOCs) were summarized and further researches on this field,especially that of trees in urban areas under the condition of multiple environmental stresses were perspected in this paper.
