贺兰山西侧山前平原地下水系统内氟离子分布规律及成因分析

The Distribution Rule and Genetic Analysis of Fluorion in Piedmont Groundwater System on the West Side of Helan Mountain

根据阿拉善左旗贺兰山山前平原地下水系统内井孔采样分析结果,得知系统内部分地区存在高氟水,地下水中F-的含量主要受F-物质来源控制。地下水中F-的富集受气候、地貌、地质、水文地质和水化学环境影响。由于系统内地下水储存条件、循环条件及影响因素不同,则地下水中F-含量差异较大。

According to the boothole sampling analysis results of piedmont groundwater system on the west side of Helan Mountain, Alxa Left Banner, this paper points out that there is the high-fluorine water in some parts of the system, and the F-content in the groundwater is controlled mainly by the material sources, and the F-enrichment in the groundwater is influenced by the climate, topography, geology, hydrogeology and hydro-chemical environment, and because the differences of water＇s storage conditions, cyclic conditions and influence factors,the difference of the F-content in the groundwater is bigger.
