摘要
本文从能量平衡原理和质量守恒定律出发,描述了土壤-植物-大气连续体中的热量转换和水分输送,模拟了系统中水分和热量的动态变化过程,并用所建立的模拟模型计算了冬小麦群落的冠层温度、叶水势及系统的潜热与显热变化关系,结果表明该模型有一定的可靠性。
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.
