摘　　要：高氟地下水的形成机理研究是目前相关理论研究的关键问题,文章在系统思想指导下将传统的水化学类型分类方法进行改进,以组态分析的方法进行形成机理研究,得出以下结论:(1)高氟地下水的形成是多因子协同作用的结果;(2)作为非线性系统,高氟地下水的形成是个多态问题,就某一个区段而言是一个"暂态",一直处于多态的变化过程中,在此过程中各个因子相互作用形成多组态;(3)Na+>Ca2+型的水化学组态的高氟率(平均51%)明显大于Na+<Ca2+型(平均12%),在高氟区段,具有代表性的水化学组态有Na.Mg.Ca-H.S.C、Na.Mg.Ca-H.C.S,其高氟概率分别为86%、76%。The study of high fluoride groundwater formation mechanism is very important.Under the guidance of system theory,classification of traditional water chemistry was improved and configurating analysis was used to study the formation mechanism.It was found that high fluoride groundwater was formed by synergic functions of multiple components.As for non-linear system,high fluoride groundwater formation was polymorphic.As for one section,it was a temporary state,and continually changing.The high probability of water chemistry configurate of Na＋ Ca2＋ was more than Na＋ Ca2＋ type.In high fluoride groundwater,water chemistry configurates of Na.Mg.Ca-H.S.C and Na.Mg.Ca-H.C.S were representative,with high probability as 86% and 76% respectively.
