沧州市浅层地下水的咸化和淡化

Increase and decrease in salinity of the shallow groundwater in Cangzhou

摘要

摘要: 文章通过分析沧州市浅层地下水的长序列水位和水质历史资料,研究了河北平原地下咸水(非海相盐分起因)的形成原因。结果表明:区内地下水的咸化和淡化过程主要取决于当地的地质环境,咸化过程是研究基础,淡化则是已咸化地下水的稀释或混合过程。

Abstract: This paper discusses the salinization processes of groundwater(non-marine saline origin) in the eastern part of the Hebei Plain by analyzing the historical water-level and water-quality data of observation wells.The results indicate that change in Cl~-concentrations in selected wells depends on the local geological environment.Based on initial Cl~-concentrations in saline groundwater, the decrease in salinity shows a dilution or mixture with the infiltrating fresh water.
