Published information about the effects of ozone on plants and ecosystems is synthesized into a conceptual model to explain the response of evergreen conifers, deciduous hardwoods and agricultural crops to ambient levels of ozone pollution. The effects of ozone on carbon balance and growth of individual plants can be quantified on the basis of concentration, external dose (concentration x duration of exposure), or uptake. For an equivalent dose within a single growing season, agricultural crops are the most sensitive to ozone, with hardwoods intermediate and conifers least sensitive. In contrast, all species display a similar decline in photosynthesis and growth in response to equivalent total uptake or uptake per leaf life span, with trees somewhat less sensitive than agricultural crops on a calendar time scale, but slightly more sensitive on a relative (leaf life span) time scale. Among species, differences in ozone uptake and response can be predicted from differences in the inherent leaf diffusive conductance.
已发表的有关臭氧对植物和生态系统影响的信息被综合成一个概念模型，以解释常绿针叶树、落叶阔叶树和农作物对环境水平臭氧污染的响应。臭氧对单株植物碳平衡和生长的影响可以根据浓度、外部剂量（浓度×暴露持续时间）或吸收量来量化。在单个生长季节内，对于同等剂量的臭氧，农作物对其最为敏感，阔叶树次之，针叶树最不敏感。相比之下，所有物种在响应同等总吸收量或每片叶子寿命期内的吸收量时，光合作用和生长都会出现类似程度的下降，从日历时间尺度来看，树木比农作物略不敏感，但从相对（叶子寿命）时间尺度来看，树木则略为敏感。在不同物种之间，臭氧吸收和响应的差异可以根据固有叶片扩散导度的差异来预测。
