大气中O3与CO2浓度升高对植物影响研究进展

由于工业的快速发展，大气中的O₃和CO₂浓度有逐年上升的趋势，对植物产生了很大的影响。目前，植物对O₃和CO₂浓度变化的复合作用的响应机制研究已经成为生态学研究的热点问题。文中阐述了O₃和CO₂浓度升高及其复合作用对植物的形态特征、光合作用、抗氧化系统及生物量等生理生化机制的影响，指出目前研究中存在并有待进一步研究的问题，以期为进一步开展高浓度O₃和CO₂对植物生理生态学影响研究提供科学参考和理论依据。

Research Advance in the Effect of Elevated Atmospheric O3 and CO2 on Plants

With the rapid industrial development, O₃ and CO₂ concentration in the atmosphere has increased year after year, which has imposed a great influence on plants. Currently, the mechanisms of plant response to the multiple effects of O₃ and CO₂ concentration changes have become a hot topic in ecological research. The paper described the influences of the elevated concentrations of O₃ and CO₂ and their multiple effects on physiological and biochemical mechanisms such as morphological characteristics, photosynthesis, antioxidant systems and biomass. The issues that exist in current study or that need further study were pinned down. This study was expected to provide a scientific reference and theoretic basis for the further research on the impact of high O₃ and CO₂ concentration on the physiology and ecology of plants.
