摘　　要：以山尔省曹县为例，通过实地调查和样品采集分析，对高氟地下水的分布特征及成因进行了研究．结果表明：曹县浅层地下水中F-含量范围为0．2—3．2mg／L，超标高氟水呈片状广泛分布；大部分深层地下水F-含量也超出国家饮用水口生标准，需增设除氟设备降氟，才可作为供水水源．高氟的岩石和土壤是本区高氟水形成的物质基础，由于蒸发作用强烈，地形平坦低洼，地下水径流排泄不畅，加上适宜的水化学条件，造成了地下水中F-的累积和富集．此外，农业污染有可能是形成本区高氟地下水的人为原因．Distribution characters and origin of high - fluorine groundwater in Caoxian of Shandong Province were studied based on field investigation and samples collection. The results show that fluorine concentration of shallow groundwater in Caoxian ranged from 0.2 mg/L to 3.2 mg/L and high fluorine groundwater is widely distributed in study area. Fluorine concentration of most deep groundwater cannot measure up sanitary standard for drinking water, so fluorine control methods are necessary for human health. High fluorine rock and soil are the foundation of high fluorine groundwater. Soil and rock with high fluorine in Caoxian were leached by precipitation and flowed into groundwater, and fluorine was cumulated and enriched for strong evaporation, low -lying landform and groundwater discharged difficultly as well as suitable hydro -geochemistry condition. In addition, human activities, for example farming pollution, may increase fluoride of groundwater.
