摘　　要：为了探讨水氟与水质指标（pH、电导率和浊度）、土壤氟、大气降雨之间的相关性,测定了金华市萤石矿区各种水体的氟含量。结果表明,水氟含量范围在0.11~14.63 mg/L之间,算术均值为1.78 mg/L。水氟含量符合对数正态分布。矿区水氟明显高于非矿区,4个矿区地表水氟平均值排序为冷水坑矿区〉杨家矿区〉大仁矿区〉花街矿区。相关性分析表明：水氟与电导率显著正相关,与浊度、土壤氟含量呈极显著正相关,而与pH无明显相关性。此外,大气降雨对本区水氟含量有影响。Water fluorine in Jinhua fluorite ore areas was measured to discuss the correlation between water fluorine and water-quality index（p H, conductivity and turbidity）, soil fluorine content, and rainwater, respectively. It is shown that water fluorine contents, which conform to logarithmic normal distribution, range from 0.11 to 14.63 mg/L, with an average value of1.78 mg/L. Water fluorine contents in fluorite ore areas were significantly higher than that of non-ore area. The average water fluorine contents of four fluorite ore areas were decreased in the order as Lengshuikeng Yangjia Daren Huajie.Correlation analysis shows that a significant positive correlation between water fluorine contents with conductivity of water was found. There was an extremely significant positive correlation between water fluorine contents and turbidity, and soil fluorine contents, respectively, while no correlation with p H. In addition, the atmospheric rainwater has influence on the water fluorine content in this area.
