Tropospheric ozone is a dangerous atmospheric pollutant for forest ecosystems when it penetrates stomata. Thresholds for ozone-risk assessment are based on accumulated stomatal ozone fluxes such as the Phytotoxic Ozone Dose (POD). In order to identify the effect of ozone on a Holm oak forest in central Italy, four flux-based ozone impact response functions were implemented and tested in a multi-layer canopy model AIRTREE and evaluated against Gross Primary Productivity (GPP) obtained from observations of Eddy Covariance fluxes of CO. To evaluate if a clear phytotoxic threshold exists and if it changes during the year, six different detoxifying thresholds ranging between 0 and 5 nmol O m s were tested.

探索臭氧风险评估的新策略：动态阈值案例研究
当对流层臭氧穿透气孔时，对森林生态系统来说是一种危险的大气污染物。臭氧风险评估的阈值基于累积的气孔臭氧通量，例如植物毒性臭氧剂量（POD）。为了确定臭氧对意大利中部圣栎森林的影响，在多层冠层模型 AIRTREE 中实施和测试了四种基于通量的臭氧影响响应函数，并根据从观测中获得的总初级生产力 (GPP) 进行了评估CO 涡流协方差通量。为了评估是否存在明确的植物毒性阈值以及该阈值在一年中是否发生变化，测试了 0 至 5 nmol O ms 之间的六种不同的解毒阈值。
