摘要: 以土壤水分运动基本方程为依据,根据长白山北坡山地棕色针叶林土的实际土壤层结构,建立了该地区一维垂向非饱和土壤水分运动数学模型,并推导了该模型的数值离散方程,编制了用于该模型数值模拟的计算程序.最后通过数值模拟对模型进行验证.结果表明,模拟值与实测值能够较好吻合.

Abstract: This paper established a mathematical model to simulate the vertical one-dimensional flow processes in unsaturated zone, based on the basic equation of soil water movement and the actual layer structure of coniferous forest brown soil on northern slope of Changbai Mountains. The numerical discrete equations of this model were derived, and the procedure for the numerical simulation of the model was programmed. This model was validated with numerical simulation, and the simulation values were consistent well with the measurements.
