摘要/Abstract

摘要： 清江下游地区发育一套第三系的红层,其岩性为砂岩夹泥岩、页岩,下部以成分为灰岩、白云质灰岩为主的砾岩。厚度在300 m以上,有一定程度的岩溶发育,其中一个洞穴具有开发价值。为进一步掌握红层地下水水质变化趋势,对红层区地下水采集30组样品进行测试,应用描述性分析、相关性分析等统计方法,总结地下水类型及水化学特征。结果表明:红层区地下水类型主要以 HCO₃-Ca 或 HCO₃-Ca·Mg 型为主,地下水化学成分具有明显的空间变异性;2个水点Al超出了地下水V类质量标准值(500 μg/L),应引起重视,防治水质污染;19个水点的Sr含量超过了天然饮用矿泉水的标准值(200 μg/L),建议进行锶矿泉水的评估工作。

Abstract: The Tertiary red-bed, widely spread in the downstream of Qingjiang River, is composed of sandstone with mudstone, shale,and the bottom of conglomaerate. The thickness is more than 300 meters, some degree of karst development, one of which karst caves has the development value. To further grasp the red layer of groundwater quality change trend, 30 groups of samples were taken from the red beds area groundwater, using descriptive analysis, correlation analysis and other statistical methods, the hydrochemical characteristics of groundwater are summarized.The results showed that the groundwater type in the red zone was mainly based on HCO₃-Ca or HCO₃-Ca·Mg, and the groundwater chemical composition had obvious spatial variability. Two points Al exceeds the standard value of the groundwater V quality(500 μg/L), which should be taken seriously to prevent water pollution. The Sr content of 19 water points exceeds the limit of natural drinking mineral water(200 μg/L), which suggests the evaluation of strontium mineral water.
