摘要
基于土壤水分运动基本理论,建立了地表滴灌条件下土壤水分运动二维数学模型;应用VB与MATLAB的混合编程技术,通过ActiveX自动化方式和文件传递参数方法,实现了VB中调用MATLAB文件对地表滴灌土壤水分运动进行模拟;另外,重点介绍了土壤水分特征曲线函数的参数计算以及渗透系数拟合公式的程序实现过程。
The paper builded two-dimensional mathematical model of soil water movement under Surface drip irrigation condition,based on theory of soil water movement.Using the mixed program of VB and MATLAB by ActiveX automation and document transfer reference,it realized the simulation of soil water movement under surface drip irrigation through invoking MATLAB files in VB.And mainly it introduced the program procedure of the parameters calculation of soil moisture feature curve function and the fitting formulas of permeability parameters.
