摘要
北京地区地下水中盐分为研究对象,在资料收集、野外调查、样品采集及测试分析的基础上,结合区域地质、水文地质等特点,分析研究区内地下水盐分的分布特征,对盐分形成的影响因素进行统计和相关性分析,并利用Visual MODFLOW软件建立地下水量、水质模型,对地下水流场、溶质运移模型进行率定,并模拟地下水污染物运移,得出地下水中盐分迁移变化规律。根据盐分迁移变化机理及模型预测结果提出该地区的污染防治方案,为该地区地下水盐分污染防治提供一定的理论基础。
The object of study for salt in the groundwater in the Beijing area, on the basis of the data collection, field inves-tigation, sample collection and test analysis, with regional geological and hydrogeological characteristics of study area, analy-sising and research area groundwater salinity distribution characteristics,formationing the statistics of influence factors of salt and analysising the correlation,then by using the Visual MODFLOW software underground water quantity, water quality model is established, calibrationing of groundwater flow and solute transport model, simulating groundwater pollutant migra-tion, understanding salt in the groundwater migration change rule.According to the results of salt migration change mechanism and model prediction and put forward the pollution prevention plan, for the region groundwater salt pollution prevention and control to provide certain theoretical basis.
