摘要(Abstract)：

大同盆地是典型的高氟地下水分布区,其分布规律和成因在类似地区具有代表性。在对盆地地下水水化学特征和空间变化特征分析的基础上,深入讨论了高氟地下水的空间分布规律、控制因素及其形成的水文地球化学过程。结果表明,整个盆地浅层孔隙水中的氟质量浓度普遍较高,变化范围为0.29~6.22mg/L,平均值为1.82mg/L。氟质量浓度高值区主要分布于盆地中部和北部,呈现出由盆地边缘至盆地中心,质量浓度趋向于升高的变化规律。强烈的蒸发浓缩作用以及高pH、高碱度、高钠低钙含量的水化学特征有利于氟富集。大同盆地高氟地下水的形成是含氟矿物的溶解、离子交换和蒸发浓缩作用等水文地球化学过程共同作用的结果。
