摘　　要：高氟地下水是一种典型劣质水源,长期饮用可致人体患地方性高氟病。本次研究以禹城—平原地区为研究对象,对区内地下水进行氟含量、水化学类型和氟离子的影响因子等研究。结果表明,浅层地下水氟离子含量大部分不超过1.0 mg/L,其水化学类型主要有HCO_(3)-Na和Cl·SO_(4)-Na型,深层地下水氟离子含量大部分均超过1.0 mg/L,其水化学类型为HCO_(3)·SO_(4)-Na和HCO_(3)·Cl-Na型。通过对pH和地下水水化学演化因素的研究,认为碱性环境一定程度能够促使氟离子聚集,但并不是唯一决定因子,高氟水的形成机制主要是水岩相互作用和蒸发浓缩作用。High fluorine groundwater is a typical poor quality water source.It can cause endemic high fluorine disease.In this study,taking Yucheng Pingyuan area as the research object,the fluorine content,hydrochemical types and influence factors have been studied.It is showed that most of the fluorine content in shallow groundwater is not more than 1.0mg/L,and hydrochemical types are mainly HCO_(3)-Na type and Cl·SO_(4)-Na type.Most of the fluorine content in deep groundwater is more than 1.0mg/L,and hydrochemical types are HCO_(3)·SO_(4)-Na type and HCO_(3)·Cl-Na type.Based on the study of pH and chemical evolution of groundwater,it is regarded that alkaline environment can promote fluorine ion aggregation to a certain extent.It is not the only decisive factor,and the formation mechanism of high fluorine water in this area are mainly water rock interaction and evaporation concentration.
