摘　　要：基于MATLAB平台,应用有限差分法,对以土壤含水率(θ)为应变量的一维非饱和土壤水分运动模型进行了离散,得到了该模型的有限差分方程,并对其进行了模拟。结果表明,该模型形式简单,计算简便,符合应用要求。Based on the MATLAB platform, using the fmite difference method, the one dimension water movement model in unsaturated soil with soil content （0） as dependent variable was dispersed, then the finite difference equation of the model was built. The soil water movement was simulated according to the model. Results showed that the model was suitable to practical application with its simple form and convenient calculation.
