摘要
文章在资料收集、水文地质调查、取样分析的基础上,研究了安徽省淮北平原浅层地下水中氟的分布规律和来源,结果表明：高氟水主要分布于淮北平原西部、北部河间地区,面积2 085 km2,ρ（F-）平均为1.05 mg/L,且高氟水地区与土壤水溶性氟ρ（F-）为4.5~6.0 mg/L的地区范围有一定的重合性;淮北平原浅层地下水氟分布受到自然风化和人类活动共同作用控制,高氟水分布中心区和主要城镇基本一致,但F-与Cl-相关关系不强;F-分布与环境条件有关,F-与Ca2＋的负相关性表明高ρ（Ca2＋）的环境有利于F-沉淀下来;F-与pH值的正相关性表明该地区的偏碱性地下水环境为矿物岩石溶解提供了有利条件。
The distribution rule and contamination source of fluorine in shallow groundwater of Huaibei Plain,Anhui Province were investigated in this paper based on data collection,hydrogeologic survey and sample analysis.The results indicate that the high-fluorine water is mainly located in the shallow groundwater of west of Huaibei Plain and north interchannel area,and the average fluorine content is 1.05 mg/L and total area is 2 085 km2,meanwhile the region with high fluorine coincides with the region that contains water-soluble fluorine of 4.5-6.0 mg/L in the soil to some extent.The distribution of fluorine in shallow groundwater of Huaibei Plain is controlled by both human activities and natural weathering process： in general,the distribution of high-fluorine water of main urban central areas is in agreement with that of main towns,however the correlation of F-and Cl-is weak.Environmental conditions have impact on the distribution of the F-： the negative correlation between F-and Ca2＋ indicates that the reaction between these two ions leads to the precipitation of F-as the forms of phosphorus-containing ores and fluorite,etc.,and the positive correlation between F-and pH implies that the slight alkaline groundwater environment in this area provides an advantage for the dissolution of minerals.
