Model description
The mechanistic canopy photosynthesis model includes three components: (i) a canopy architectural model; (ii) a forward ray tracing algorithm; and (iii) a steadystate biochemical model of photosynthesis. The different physiological parameters for individual leaves can be incorporated into this model. As a result, this model predicts different architectural and physiological properties on canopy photosynthetic CO2 uptake rates. With this model, even the impacts of varying growth regions and planting density, planting direction on the total canopy photosynthetic CO2 uptake rates can be evaluated as well.
