土壤水、热和溶质耦合运移研究进展

总结和概括了国内外土壤水热耦合运移、土壤水和溶质耦合运移及土壤水、热和溶质耦合运移研究的基本理论和代表性成果。Philip-De Vries和De Vries的土壤热耦合运动方程与Taylor-Cary基于不可逆热力学定律的线性流动方程是土壤水热耦合运移研究的两种主要理论。土壤水和溶质迁移的数学模型，可分别由水分运动、溶质运移两个方程耦合组成。Nassar关于土壤水、热和溶质耦合运移理论的研究取得了一定进展。在此基础上，探讨了土壤水、热和溶质运移耦合系统需要进一步研究的问题。

Development in the Research on Simultaneous Transport of Heat, Water and Solute in Soils

The basic theories and outstanding results in the studies of coupled heat and water transport, coupled solute and water transport, simultaneous transport of heat, water, and solute in soils are summarized synthetically. The equations of coupled heat and water movement developed by PHILIP DE VRIES and DE VRIES and TAYLOR CARY's linear flow equations based on the law of irreversible thermodynamics are two major methods for the study of coupled heat and water transport in soils. The mathematical model of solute and water transport is composed of two coupled equations of water movement and solute transfer. Some development in the theory of simultaneous transport of heat, water and solute in soils proposed by NASSAR is required. On the basis of the formers,some further research fields of simultaneous transport system of heat, water and solute in soils are discussed.
