沟底膜孔灌水条件下土壤水入渗规律的数值模拟

Numerical simulation of soil water movement under condition of film hole irrigation

以土壤水动力学原理为基础 ,研究了沟底膜孔灌水条件下土壤水分运动规律 ,建立了二维入渗模型。对模型检验表明 ,试验实测数据与模型计算值吻合较好 ,说明所建立的模型是可行的。

Based on theory of soil water dynamics, this paper studies on the soil water movement under condition of film hole irrigation, and develops a two-dimensional infiltration model for film hole irrigation. The examination of the model shows that the results of numerical simulation of the model are in good agreement with the measured data of film hole irrigation experiment in the field and the model is reliable.
