中文摘要：
根据南水北调供水方案，南水北调进京10年后，受水区内垃圾场将会被地下水浸泡，如不采取防治措施，会对含水层水质造成严重污染。以北京西郊为研究区，利用Visual Modflow软件中的MODFLOW模块和MT3DMS模块分别建立了地下水水流模型和溶质运移模型，对研究区内污染物运移规律进行预测。预测结果表明，10a后氯离子（Cl^-）、硝酸盐氮（NO3^2-）和总硬度（THD）3种离子的最高浓度和被污染的面积均增大，预测结果可作为调整地下水开采与调蓄方案和垃圾场防渗规划设计的依据。
英文摘要：
According to the water supply scheme of the South-to-North Water Transfer Project, the dumps are soaked by groundwater on the water-recipient areas after ten years. If the prevention measures are not taken, the aquifer water quality will be severely polluted. Using MODFLOW and MT3DMS module in Visual Modflow software, the groundwater flow model and solute transport model are established and the pollution transport is predicted for a case study on the western suburbs in Beijing. The result shows that the highest concentration of three ions, including Cl^-, NO3^2- and THD, and the polluted area are becoming larger after ten years, which provides scientific basis for adjusting groundwater exploitation and storage scheme and designing seepage prevention planning.
