摘要
地下水作为中国北方地区的重要供水资源,保护地下水的水质安全是地下水资源合理开发利用的主要问题之一。以黑龙洞泉域作为研究区,以探索羊角铺水源地保护区划分为例,通过采用数值模拟的方法对研究区建立概念模型和数学模型,为减少因模型参数的不准确性带来的误差,在模型水文地质参数分区时结合遥感影像来确定含水层参数,之后再利用Visual MODFLOW软件模拟获取地下水流场和以开采井为中心溶质质点向外迁移的运动轨迹,并根据在不同的时间标准内所迁移的距离来确定地下水水源地一、二级保护区。结果表明,利用该方法客观详细地刻画了地下水水质运移的情况,保护区划分的结果可靠、准确,为相关管理部门提供了有效合理的依据。
Groundwater is an important water supply resource in northern China.Protecting the quality and safety of groundwater is one of the main problems of rational development and utilization of groundwater resources.Taking Heilongdong spring area as the research area and Yangjiaopu water source protection area as an example,both the conceptual model and mathematical model were established by numerical simulation method.In order to reduce the error caused by the inaccuracy of the model parameters,the aquifer parameters were determined by remote sensing image when the hydrogeological parameters of the model were divided,and then the groundwater flow field and the movement trajectory of the migration of solute particles centered on the mining well were obtained using Visual MODFLOW software simulation.According to the distance of migration in different time standards,the primary and secondary protection areas of groundwater source were determined.The results show that the method could objectively and detailedly describe the groundwater quality migration,and the result of the division of the protection area is reliable and accurate,which provides an effective and reasonable basis for the relevant management departments.
