地下水中氟形成的控制因素及其分布规律

本文研究了地下水中氟元素形成的主要控制因素及其分布规律。结果表明，地下水氟的形成与断裂构造，地下水温度、气候条件、含水介质及其上覆土层中的氟含量，地下水的酸碱度与径流条件有密切的关系。深成断裂脉状地下水和萤石矿区的地下水氟含量高，不有作为生活饮用水源； 而浅层的地下水氟含量较低，大多数仍作为生活饮用水源。

THE CONTROL FACTORS OF THE F FORMATION IN GROUND-WATER AND ITS DISTRIBUTIVE REGULARITY

In this paper,the main control factors of formation of the F in groundwater and its distributive regularity are studied.The result shows that the formation of the F in groundwater is closely to the faulted structures,groundwater temperature,climatic conditions,the F contents of the aqueous medium and its covered soil,acidity-akalinity of groundwater,and the runoff condition. The vein groundwater in deep fractures and aquifer in the fluorine mines have high F content,therefore,it cannot be taken as domestic potable water resource,in contrast,the upper groundwater has a low F content and can be taken as domestic potable water resource.
