潍北平原高氟地下水的分布及成因分析

Analysis on Distribution and Origin of High-fluorine Groundwater in Weibei Plain

摘要:

通过环境地质调查及水样测试，从地层、气象、地貌、水文地质等几个角度进行了系统分析，潍北平原高氟地下水的分布、形成条件受地质、气候、地貌和水文地质的控制，大气降水在入渗过程中通过水岩作用及淋滤作用将岩石和土壤中氟元素带入地下水中，在蒸发作用下浓缩，最终形成高氟地下水。

Abstract:

Through environmental geology investigation and sample test, from the aspect of strata, weather, landform and hydrological aspects, comprehensive analysis has been carried out. It is regarded that distribution of high- fluorine groundwater and formation condition are controlled by geology, climate, landform and hydrogeology. In the process of infiltration, atmospheric precipitation will bring fluorine in the soil into the undergroundwater through water rock interaction and leaching, evaporated under the action of concentrated, and formed high fluorine groundwater.
