摘要
封闭、半封闭的地理条件有利于含氟水的汇集 .古地理条件对氟的迁移和富集有一定影响 ,古河床区的碎屑沉积物有利于含氟水的入渗和迁移 ,该区表现为低氟 ;在泛流带 ,细碎屑和粘土沉积物构成含氟水富集的基底而表现为高氟区 .蒸发浓缩作用控制浅层地下水中氟的存在形式 .含氟污水农灌。
Confining or semi?confining geographical factor is advantageous to come together fluorine?bearing water.Palaeo?geographical environment influence assemble of fluorine?bearing water too.Clastic sediments in palaeo?riverbed are advantageous to permeate and move fluorine?bearing water in it.This zone is low flourine area.In overflow area,fine clastic and clay make up bottom of high fluorine content water.The area is high fluorune area.Evaporation and concentration control are the forms of?fluorine?under?coordinate?of?meteorological phenomena.Agricultural irrigation by fluorine?bearing sewage,hydrogen fluoride subsidence and employment of fluorine?bearing agricultural chemical pollute soil and shallow groundwater.
