本文研究均质土壤、表面供水强度已知但未超过土壤入渗能力的入渗模型。用FORTRAN语言编写数值计算的程序,并用垂直土柱试验验证了程序的可行性,也与Parlange解法作了比较。应用本程序对降雨或喷洒情况下的入渗;入渗后土壤水再分配;入渗后在表土蒸发或田间腾发条件下的水分运动等均进行了计算。对田间持水量和灌水管理问题进行了初步的讨论。 In this paper, the homogeneous soil is studied, and the infiltration model with known surface water supply strength but not exceeding soil infiltration capacity is studied. Numerical program was written in FORTRAN language. The vertical soil column test verified the feasibility of the program and compared with Parlange solution. The application of this program for rainfall or spray infiltration; soil water redistribution after infiltration; after infiltration in the topsoil evaporation or field conditions under the conditions of water movement were calculated. Field water holding and irrigation management issues were discussed.
