From the beginning of the 90's,the simulation of plant physiological ecology came into a stage of process\|based simulation from empirical methods We generalize and evaluate the basic processes of physiological ecology at leaf and canopy level,and then analyze some famous models and their methods in simplifying and parameterizing The leaf photosynthesis model is based on biochemical model and stomatal conductance model,such as Ball\|Berry model Canopy model is based on Ross's solar radiation transfer the...
