摘    要:经过对条件的概化,建立了带有作物根系吸水项的垂向一维土壤水分运动的数学模型,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。通改数值模拟对模型的验征,计算值与实测值拟合较好,这表明,该模型是可靠的,数值方法是可行的,可以用来模拟作物生长条件下田间土壤水分的运动。

关 键 词:数学模型,数值模拟

Abstract:Through simpllflcation to the conditions, the mathematical model of one-dimensionalsoil water flow with the water uptakd by the crop root is set up, and the numerical simulationprogram of the model is compiled. The results of calculation are that the simulated values and themeasured data ard very close. This shows that the model is reliable, the numerical method is feasible, and the model can be used in simulating soil moisture movement in field on the condition ofthe crop growth.
Keywords:mathematical model  numerical simulation
