臭氧（O3）是公认的最重要的空气污染物之一。目前，根据最悲观的预估，全球对流层臭氧平均浓度已从工业化前估计的38 nl L(-1) （25-45 nl L(-1)， 8小时夏季平均）在2000年增加到约50 nl L(-1)，到2100年增加到80 nl L（-1）。水稻是世界上最重要的粮食作物，因此，正确评价近地表O3浓度升高对水稻生长发育的影响具有重要意义。本文综述了大气臭氧富集对水稻可见损伤症状、光合作用、水分关系、物候、干物质生产与分配、叶膜保护系统、籽粒产量及其组成部分的影响。展望了该领域今后的研究方向。
Ozone (O3) is recognized as one of the most important air pollutants. At present, the worldwide average tropospheric O3 concentration has been increased from an estimated pre-industrial level of 38 nl L(-1) (25-45 nl L(-1), 8-h summer seasonal average) to approximately 50 nl L(-1) in 2000, and to 80 nl L(-1) by 2100 based on most pessimistic projections. Oryza sativa L. (rice) is the most important grain crop in the world, and thus, to correctly evaluate how the elevated near-surface layer O3 concentration will affect the growth and development of rice is of great significance. This paper reviewed the chamber (including closed and open top chamber)-based studies about the effects of atmospheric ozone enrichment on the rice visible injury symptoms, photosynthesis, water relationship, phenology, dry matter production and allocation, leaf membrane protective system, and grain yield and its components. Further research directions in this field were discussed.
