Abstract: The increasing concentrations of CO2 and O3 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 CO2 and O3 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.

Key words: Biogenic volatile organic compounds(BVOCs), Elevated atmospheric CO2, O3
