中文摘要：

引用国内外大量文献，对CO2和O3浓度升高特别是它们的交互作用对农作物次生代谢及残茬分解的影响等进行综述。重点阐述了农作物生长、次生代谢、残茬分解对大气CO2和O3浓度升高（特别是在升高后的交互作用下）的响应变化，客观地反映其生物学和生态学效应，进一步提出建议，以期引起学术界对该课题的关注。

英文摘要：

The increasing concentrations of CO2 and O9 in troposphere have become a focus of attention from both domestic and foreign researchers. The effects of single and joint action of CO2 and O3 on secondary metabolism of crops and decomposition of organic residues were summarized, and further researches on this area were prospected in this paper. This paper aims at introducing the effects of the compounds on secondary metabolism of crops attended by introducing composing approach and function of secondary metabolism and impacts of elevated CO2 and O3 concentrations. It brought the attention on the effects of elevated CO2 and O3 concentration on crop productivity, secondary metabolism and residue decomposition, especially for the interactive effects of elevated CO2 and O3, and impersonality expressed the biological and ecological effects.
