摘　　要：土壤中的氟处于淋失和富集两种地球化学作用过程的平衡之中。淋失过程占优势的条件下,在干旱半干旱地区内的特定区域形成地带性的高氟地面水和地下水,这是饮水型地方性氟中毒发生的物质基础。在氟的富集占优势的条件下,湿润气候地区将形成富氟土壤,并与其它条件结合则产生燃煤型地方性氟中毒。在决定风化壳中氟平衡状态的诸因素中,粘土矿物对氟的吸附与解吸附性质是最关键的因素。Fluoride is in the geochemical balance of enrichment and leaching in the soils.Under the conditions of the leaching process being dominant,high-fluoride surface water and groundwater form in the arid and semi-arid areas,and drinking water type endemic fluorosis forms.Under the conditions of the enrichment being the dominant process,fluorine-rich soil forms in humid climatic regions,and combined with other conditions coal-combustion type endemic fluorosis forms.Fluoride adsorption and desorption on clay minerals is the most critical factor in the various factors affecting the equilibrium of fluorine in weathering crust.
