一个组合模型来模拟CO2和H2O气体交换在叶尺度上的参数化使用的数据从现场叶尺度观测的CO2和H2O气体交换的日变化和季节变化的四个温带落叶阔叶树，使用孔隙度的方法。该模型由一个球等。型气孔导度子模型[Ball，Woodrow & Berry，pp. 221-224 in Progress in Photosynthesis Research（ed. I. Biggins），Martinus-Nijhoff Publishers，多尔德雷赫特，荷兰，1987]和Farquhar等。类型的光合作用的生化子模型（Farquhar，von Caemmerer & Berry，Planta 149，78-90，1980）。在这些子模型中，几个参数进行了优化，为每个树种作为代表的气体交换相关的定量特征。结果表明，光合作用生化模型中V-cmax 25的季节性生理变化可用于估算长期CO2气体交换量。对于光合作用生化模型中的R-d25和Ball et al .型气孔导度模型，应在展叶期计算差异。
A combined model to simulate CO2 and H2O gas exchange at the leaf scale was parameterized using data obtained from in situ leaf-scale observations of diurnal and seasonal changes in the CO2 and H2O gas exchange of four temperate deciduous broad-leaved trees using a porometric method. The model consists of a Ball et al . type stomatal conductance submodel [Ball, Woodrow & Berry, pp. 221-224 in Progress in Photosynthesis Research (ed. I. Biggins), Martinus-Nijhoff Publishers, Dordrecht, The Netherlands, 1987] and a Farquhar et al . type biochemical submodel of photosynthesis (Farquhar, von Caemmerer & Berry, Planta 149, 78-90, 1980). In these submodels, several parameters were optimized for each tree species as representative of the quantitative characteristics related to gas exchange. The results show that the seasonal physiological changes of V-cmax25 in the biochemical model of photosynthesis should be used to estimate the long-term CO2 gas exchange. For R-d25 in the biochemical model of photosynthesis and m in the Ball et al . type stomatal conductance model, the difference should be counted during the leaf expansion period.
