摘要
基于土壤水动力学原理,建立了针对地下滴灌(SDI)具体条件下土壤水分运动的数学模型。对建立的特定模型进行了ADI交替隐式差分求解。模拟计算结果得到了室内试验的验证。
Based on the principle of soil-water dynamics, a mathematical model of soil-water movement is presented for subsurface drip irrigation (SDI). Alternative direction implicit technique (ADI) is used to solve specific SDI model developed by the authors. Results of simulation are verified by the results of laboratory test.
