Compared simulating value of model with measured value, the error was below 3% and relative coefficient was over 0. 9. The dispersion coefficient and average pore-water velocity of nitrate vertical transport in simulating process were also obtained. 在模拟过程中可同时得到销态氮垂直运移的弥散系数和平均孔隙水流速(averagepore-watervelocity)等参数。因此该模型可以直接用来确定农田土壤中硝态氮垂直运移的参数。
