摘　　要：选取具有典型意义的吉林省通榆县等地氟病高发区和松嫩平原作为研究区,对地下水及含水层进行系统取样,运用描述性统计分析及相关性分析等方法,综合研究松嫩平原地下水中氟的分布、来源及影响因素。结果表明:松嫩平原高氟地下水主要分布于第四系潜水中,平原四周及含水层组富氟的地质环境是其主要来源区,地貌条件、气候因素及水化学条件影响地下水中氟的富集与扩散,研究区第四系及前第四系承压水水量丰富,水质良好,氟含量低于规范要求,可作为地氟病区防氟改水的主要供水目的层。Taking the Songnen Plain,especially Tongyu County and other places in Jilin Province where the endemic fluorosis is typical,as the objective area,the authors systematically obtained the groundwater and aquifer samples.With descriptive statistic analysis and correlative analysis,we studied the distribution,source and influencing factors of the fluorine in groundwater.The results show that the high-F groundwater in Songnen Plain occurs mainly in the Quaternary phreatic water.The F-rich aquifer around the plain performs the major source of fluorine.The enrichment of fluorine in groundwater is affected by geomorphologic condition,climate factor and hydrochemical condition.It is concluded that the Quaternary and pre-Quaternary confined water,with abundant water amount,good quality and standard-reached F content,can be used as the main supplier of water for the endemic fluorosis areas.This study will provide scientific basis for the fluorosis preventing and water resources administration in Songnen Plain.
