| 摘 要： | 本文分析了线水源条件下地下滴灌土壤水运动的物理过程，认为其土壤水运动是一垂直毛管的平面二维流动；在此基础上，建立了饱和──非饱和土壤水二维流动的数学模型。采用ＡＤＩ法，结合Ｐ－Ｃ法对模型进行求解。计算结果与室内试验基本相吻合。

| Abstract: | Based on analysis of the physical process of soil water movement under line source condition of subsurface drip irrigation,a method of the numerical simualtion for predicting soil water movement under subsurface drip irrigation is presented.The model is solved by combining finite difference method(FDM)procedure involving the use of alternative direction implicit(ADI)and predictive-correction(P-C) techniques.Data obtained from the comparision between numerical simulation results and experiments showed that this model is right and applicable. |
