摘要
本文在室内试验的基础上，提出了考虑土壤吸附作用时非饱和土壤溶液中ＮＨ＋４－Ｎ浓度的计算方法，并对氮肥（碳铵：ＮＨ４ＨＣＯ３）在非饱和土壤中的运移与转化过程进行了数值模拟．
On the basis of laboratory experiments, the calculation method for concentration in unsaturated soils moisture considering soil absorption is developed. The mathematical model of the transport and transformation of NH-N in unsatutsted soils is established and solVed by the method of finite difference. The calculated results are compared with the observed data, well agreement is attained.
