| 摘 要： | 本文从土壤水热耦合运移的基本方程出发，依据能量平衡原理和质量守恒定律，系统地描述了ＳＰＡＣ中的水分传输和能量转换，模拟了系统中水分和热量的动态变化过程。经夏玉米生育盛期模拟值与实测值的比较分析表明，用本文提出的模型模拟田间土壤水热动态和作物生理特性的变化过程具有较高的精度。

| Abstract: | Starting from basic equations of moisture and heat movement and based on the principle of energy balance and the law of conservation of mass,the paper presents systematically not only moisture transport and heat transmorfation, but also simulation of dynamic changes of moisture and heat. Comparisons of simulated values and measured ones for summer corn field show that the model developed in this paper has a higher precision and gives an ideal approch to the solution of some of the problems in agriculture production. |
