摘　　要：分析焦作地区浅层地下水硬度污染物与地下水其他化学特征的相关性,研究该区浅层地下水硬度的污染机理,运用Visual Modflow软件建立水质模型,模拟预测浅层地下水中硬度污染物的迁移规律。结果表明:该区浅层地下水硬度污染严重,主要原因是工矿企业污废水排放和对浅层地下水的不合理利用,造成进入浅层地下水的污染物增多,直接引起浅层地下水硬度升高;另一方面使得本区浅层地下水的化学场、动力场发生变化间接引起本区浅层地下水硬度升高。模拟结果显示,浅层地下水中硬度污染物的迁移明显受到水文地质条件的影响,迁移方向与地下径流方向基本一致,自西北向东南方向迁移。Based on the characteristics of distribution hardness pollutants of shallow groundwater in Jiaozuo area, the correlations between the hardness of shallow groundwater and other chemical characteristics of shallow groundwater were analyzed. We studied the pollution mechanism of hardness of shallow groundwater in this area, used the Visual MODFLOW software to establish a model of water quality, and simulated and predicted the rule of migration of hardness in shallow groundwater. The results show that the main reason of hardness pollution of shallow groundwater in this area is industrial wastewater discharge and irrational utilization of shallow groundwater. These unreasonable production and development activities, on one hand, make more pollution into shallow groundwater, resulting in direct increase of hardness of groundwater. On the other hand, these reasonable activities make the chemical field and force field changed, causing the hardness of shallow groundwater increased indirectly. Simulation results show that the migration of hardness contaminant in shallow groundwater, from northwest to southeast just along the groundwater flow direction, is affected by hydrogeologieal conditions.
