近地层臭氧作为最重要的大气污染物之一, 对植物形态特征、光合作用、生育期、物质生产与分配、抗氧化特性、生物量以及产量构成等都有显著负面影响, 已成为当今世界研究者及公众关注的重要问题.目前由于人类活动和工业迅猛发展, 近地层臭氧浓度正以每年0.3%～2%的速度增加, 准确评估近地层浓度不断升高的臭氧对植物的影响具有重要意义.本文从浓度响应关系、剂量响应关系和通量响应关系3个方面综合评述了植物对近地层高浓度臭氧响应的评价方法及其国内外研究进展, 同时对各评价方法的优缺点进行了总结比较, 旨在为建立适合我国地域和农业特点的臭氧污染评价指标体系和方法提供科学依据.

Elevated near-surface ozone is one of the most important air pollutants with a range of negative impact on plants, including plant morphology, photosynthesis, growth, material production and distribution, antioxidant property, biomass and yield component, etc. arising a considerable scientific and public concern. At present, ambient ozone concentration is increasing at the rate of 0.3%～2% per year due to increased human activity and rapid industrial development. Accurate assessment of elevated tropospheric ozone impact on plants is an absolute necessity. This paper reviews the evaluation methods (including relationships based on concentration, dosage and flux) of the effect of elevated tropospheric ozone concentration on plants. The merits and demerits of the evaluation methods are also compared and summarized. This review may lay scientific basis for establishing ozone concentration evaluation index system that is adaptable to China's geographic and agricultural characteristics.
