摘　　要：系统收集和整理了国内外关于CO2和O3复合胁迫对森林影响的研究,从两者的复合胁迫对森林树木的光合作用、地上部分生长、根系生长、土壤环境、种间竞争的影响等方面进行了阐述,并对该领域有待深入研究的方向进行了展望;提出应深入开展对植物地下水平和分子水平的研究,为解决全球气候变化对森林造成的影响提供借鉴,同时为生态系统的管理提供依据。The concentration of CO2 and O3 near the ground has increased day by day because of the global climate change, which has a significant impact on plants, while forest play an important role in adjusting structure and function of the ecosystem. Thus, it is of great significance to correctly evaluate how the interactions of elevated CO2 and O3 concentration near surface layer will affect forest ecosystem. This paper reviewed the interactive effects of atmospheric CO2 and O3 enrichment on forest at domestic and abroad. Photosynthesis, above- ground growth, under- ground growth, soil environment and inter0 specific competition have been expatiated. Future research directions in this field were discussed and it was proposed to carry out more in - depth research on under - ground level and molecular level of plants, in order to provide references for mitigate the influence of global climate change on forests and provide the basis for the management of the ecosystem.
