| Abstract: |
| The rapid growth of fossil fuel-based economies during the last several decades has increased emission of ozone precursors, and thus raises atmospheric ozone concentrations. It is well documented that high ozone concentrations have negative effects on agricultural crops and induce significant yield losses in species such as wheat, rice and soybean. The negative effects of elevated ozone on the crops and food safety have drawn extensive attentions. It is important to establish more accurate models for evaluating the yields loss of crops under elevated surface ozone, and ensuring food security and controlling ozone pollution. In this review, concentration response, dose response and flux response models and their applications to biomass and yield loss were evaluated. Dry deposition models of surface ozone and flux model were compared. Based on the observation and ozone dry deposition model, a new research field was proposed to study techniques for evaluating crop yields loss under ozone stress in the natural farmland ecosystems. |
