模拟氮在人工快渗系统运移转化的可行性分析

Solute transfer model in the porous media is an important method in researching the solute transportation and transition process in soil. The transportation and transition process of nitrogen in the constructed rapid infiltration (CRI) system and the agricultural soil system are similar. By comparing the transportation and transition process of nitrogen in CRI and agricultural soil system, the feasibility of simulation the transportation and transition process of nitrogen in CRI with soil solute transfer theory is discussed. After analyzing the main characteristics and research status of soil transfer model at home and abroad, It is pointed out that the Convection-Dispersion Model is more appropriate to simulate the transportation and transition process of nitrogen in CRI, and the problems which may be aroused in the simulation are also discussed.
