一、前言研究非饱和土壤水分运动的基本途径是数值模拟和实验。用计算机模拟非饱和土壤水分运动从60年代以来不断有研究成果,非饱和土壤水分运动的研究经验到理论,由定性到定量的深刻变化。由于土壤水分运动是一个十分复杂的过程,很多模拟研究的成果只能适用于某些特定的情况,通
I. INTRODUCTION The basic ways to study the movement of unsaturated soil moisture are numerical simulation and experiment. Computer simulation of unsaturated soil moisture movement from the 1960s continuous research results, the unsaturated soil moisture movement research experience to theory, from qualitative to quantitative profound changes. Because soil moisture movement is a very complicated process, the results of many simulation studies can only be applied in some specific situations.
