摘要
根据已测定的土-水系统反应动力参数和动力学参数,确定了土壤的物理性质和化学性质,建立了研究区典型剖面上的水量-水质耦合模型,采用数值分析方法,模拟不同土壤在不同条件下水分和氮污染物的迁移、分布和转化规律,对参数进行调整,可以分析不同影响因素对土-水系统中氮污染的影响程度,从而提出合适的调控方案。
According to recent monitored parameters of the dynamic reaction of the contaminants in the water-soil system and the hydro-geological parameters in the vadose zone, physical and chemical properties of were confirmed. The mass-flow coupling model of the typical profiles was established. The numerical simulation was attempted to simulate the regulation of the migration distribution and transformation of the nitrogen in the soil - water system. In this dissertation, the numerical simulation was attempted to simulate these processes on different initial and boundary conditions, then some practical plans were presented to control the groundwater contamination.
