中文摘要:

以揭示高氟地下水氟富集机理为研究目的,在了解关中盆地水文地质的基础上,分析了高氟地下水氟富集的影响因素,并分析和讨论了其形成机理。结果表明:高氟地下水分布区其水文地质特征有一定的特点；地下水中氟的含量与水温、pH等以及地下水的水化学成分有关,HCO-₃、Na⁺促进了含氟矿物向地下水中迁移和转化,而Ca²⁺抑制氟含量的增加；因子分析表明,水-岩相互作用,碳酸盐矿物的溶解和Na-Ca离子交换控制着关中盆地地下水氟富集的主要水化学过程；包气带中可溶性氟向下迁移主要是受溶滤作用影响,而氟在地下水中的富集则取决于蒸发浓缩作用。

英文摘要:

In order to reveal the enrichment mechanism of groundwater with high fluoride based on the hydrogeological conditions in the Guanzhong basin, the paper analyzed the impact factors of fluoride enrichment in groundwater. The results showed that high fluoride distribution in groundwater has certain hydrogeological characteristics. The fluoride content in groundwater contacts with water temperature, pH and chemical composition. HCO-_3and Na + promote the migration and transformation of fluorine-containing minerals to groundwater, but Ca²⁺ dominate the increase of fluoride content. Factor analysis showed that the water-rock interaction, dissolution of carbonate minerals and Na-Ca ion exchange controls the main hydrochemical process of fluoride enrichment of groundwater in Guanzhong basin. The soluble fluoride in vadose zone migrates downward mainly because of leaching effect.The fluoride enrichment is depend on the role of evaporation and condensation.
