对宁夏盐池地区的地下水和土壤、岩石中的含氟量进行了系统调查。结果表明:盐池地区处于强烈的干旱积盐环境中,水土环境呈碱性反应。第三系泥岩和侏罗系泥砂岩地层的含氟量远高于其它地层,为本地区高氟地下水的主要形成因素之一。风积沙、厚层第四系冲洪积层和白垩系砂岩地层为本地区的主要低氟水赋存地层,是今后找水的目标含水层。 The amount of fluorine in groundwater, soil and rock in Yanchi area of ​​Ningxia was investigated systematically. The results show that the salt pond area is in arid and arid area, and the soil and water environment is alkaline. The Tertiary mudstone and Jurassic sedimentary sandstone contain much higher fluorine content than other strata, which is one of the main formation factors of high-fluorine groundwater in this area. Aeolian sand, thick Quaternary alluvium and Cretaceous sandstone strata are the main low-fluorine water-bearing strata in the region and are the target aquifers for water exploration in the future.
