摘要：Coupled model of canopy stomatal conductance (Gs) and photosynthesis (Pn) was presented. This model could simulate the response of G_s to microclimatic factors and the diurnal variation. These established models were tested by the observation data in an apple (Malus domestica) Borkh. cv. 'Fuji') orchard (latitude 40o13' north, longitude 116o13′ east, altitude 79 m). The influences of the microclimatic factors on stomatal conductance were different. There were strong interactions among the various microclimatic factors. From this model, we can see that the diurnal course of G_s in the canopy showed a double-peak curve and G_s increased as the net radiation increased and decreased as the relative humidity and water potential decreased. There was a satisfactory correspondence between measured and simulated values of G_s with observation data in the apple orchard.
