摘　　要：为研究张承地区与高氟地下水有关的地质环境要素,在充分分析大气降水、基岩、富氟矿床、土壤、温泉及地表水等氟源的基础上,选取了4个典型地方性氟中毒发病村庄进行地质环境调查,并采集地表水、地下水样品23件进行实验与测试分析,研究了地下水化学对于地下水氟离子聚集的作用。结果表明:高氟地下水的氟源主要来自富氟基岩、矿床、土壤和温泉,而大气降水及地表水提供的氟元素相对较少;地形地貌对于地下水氟含量有着直接的控制作用,地质构造通过控制地形地貌以及温泉分布,对高氟地下水的形成有着间接的影响。In order to study the geological environment factors related to high-fluoride groundwater in Zhangjiakou-Chengde area,an analysis of various fluorine sources including atmospheric precipitation,bedrock,fluorine-rich deposits,soil,hot springs,and surface water was conducted.Four typical endemic fluorosis villages were selected for geological environment investigation,and 23 surface water and groundwater samples were collected for experimental analysis,and the effect of groundwater chemistry on the accumulation of fluoride ions in groundwater was studied.The results show that high-fluoride groundwater primarily originates from fluorine-rich bedrocks,mineral deposits,soil,and hot springs,with lesser contributions from atmospheric precipitation and surface water.Topography and landform directly influence the fluoride content of groundwater,while geological structure plays an indirect role in the formation of high-fluoride groundwater by controlling topography and hot springs distribution.
