摘要
本文通过对太原市化工区120km^2区域环境水文地质条件的阐述概化,建立了二维地下水流动及溶质运移和弥散数学模型,并首次应用迭代的交替方向隐式差分法(IADI)求解了溶质运移模型。通过对氯离子的模拟研究,对研究区地下水的污染成因、污染途径作了分析探讨,并对地下水的水质发展趋势作了预报,为研究区防治污染,保护地下水资源提供了科学依据,同时也为太原市及其它城市地区进一步开展溶质运移模拟研究积累了经验。
Under describing environmental and hydrogeological conditions in the chemical industry district of Taiyuan city, 120km^2 in area, the ,mathematical model given in the paper simulates migration and dispersion of solute in flowing groundwater. The model couples the groundwater flow equation with the sohute-migration equation. An iterative altcrnating-direction implicit procedore(IADI) is used on solving the solute-migration and dispersion equation.The genesis and path of pollution of groundwater in study area are analyzed and evaluated by simulating the dion. The chamge tendency of water quality is predicted.
