土壤水分运动数学模型的建立及应用

Foundation and Application of Numerical Simulation of the Soil Water Movement

以土壤水动力学原理为基础 ,研究了垂直入渗条件下土壤水分运动规律 ,结果表明 ,试验实测数据与模型计算值吻合较好 ,说明所建立的模型及选取的参数是可行的 。

This paper, based on theory of soil water dynamics, studies the soil water movement under condition of vertical infiltration. It shows that the results of numerical simulation of model are in good agreement with the measured field data of experiment. According to the above research, the infiltration model is reliable and provides a reliable foundation for the evaluation of the water resources in the area of Xinjiang.
