中文摘要：
于2011年对环鄱阳湖区56口井的水质进行调查研究，应用SPSS和数学统计方法，研究了环鄱阳湖区地下水中氟含量特征及成因分析。结果显示：环鄱阳湖区地下水中氟化物普遍存在，F-离子浓度变化范围为0．001～0．418mg／L，平均值仅为0．089mg／L，氟含量普遍偏低，不能满足人们的日常需求，对当地居民的口腔健康存在一定威胁；土壤与岩石性质是影响地下水氟含量偏低的主要因素，另外，地下水的化学成分、气候条件、水体pH值及地下水径流条件等也都在不同程度上影响着地下水中氟的含量与分布。
英文摘要：
In South China, the phenomenon of lacking fluoride sampling wells around Poyang Lake Area was investigated to in groundwater is ubiquitous. In 2011, the groundwater quality of 56 analyze the content characteristics and causes of fluoride in shallow groundwater by applying SPSS and mathematics statistical methods. Results show that fluoride in groundwater is widely distributed around Poyang Lake Area Fluoride concentrations ranged from 0. 001 to 0. 418 mg/L, with the mean value of 0. 089 mg/L. Fluorine content is generally low, which fails to meet the daily needs of people, and has posed a certain threat to the oral health of local residents. Soil and rock properties are the main factors of low fluorine content in groundwater. In addition, the content and distribu- tion of fluorine in groundwater are affected by hydrochemistry types, climatic conditions, water pH and flow conditions of the groundwater.
