本文建立了一种使用交替方向隐式有限差分法（ＡＤＩ）来研究条带状覆盖情况下二维土壤水热流动的计算模型．该模型使用土壤表面能量平衡方程来确定热和水流的土壤表面的边界条件，讨论了模型中所需要输入的参数，并且经ＣｈｕｎｇＳ－Ｏ等人试验进行了验证，为评价地下水资源量提供可靠的依据．
In this paper, we establish a computational model of two-dimensional soil water-heat flow using the alternating-direction implicit finite difference method (ADI) to study strip-shaped soil cover. The model uses the soil surface energy balance equation to determine the boundary conditions of the soil surface under heat and water flow. The parameters required for the model are discussed and verified by the ChungS-O et al. Experiment to provide reliable estimates of groundwater resources in accordance with.
