| Abstract: | Based on the principles of energy balance and mass conservation the heat transformation and water transport processes in a soil-plant-atmosphere continuum system have been described, and canopy temperature, leaf water potential, latent and sensible heats, and soil surface temperature were calculated for winter wheat with the simulation model established in this paper. The results show that the simulated values are very close to the measured values.This model and method presented in this peper are demonstrated to have a certain reliability. |
