摘要
为研究阜阳市集中式深层地下水饮用水源地水化学特征及成因,采集阜阳市14个深层地下水样品进行测试,运用数理统计分析、Piper三线图对水化学组成及类型进行分析,采用吉布斯图、相关性分析法对水化学成因进行讨论。结果表明:阜阳市集中式深层地下水饮用水水体阳离子以Na^+为主,阴离子以HCO^-3为主,水化学类型总体上表现为HCO^-3-Na^+型;吉布斯图和相关性分析结果显示,阜阳市深层地下水受“岩石风化”和“蒸发作用”双重影响,其中以“蒸发作用”为主。另外,外界环境的改变也对离子水化学组成产生影响。
In order to study the hydro-chemical characteristics and causes of drinking water source of concentrated deep groundwater in Fuyang City,fourteen deep groundwater samples are collected and tested.Mathematical statistics and Piper three-line graph are used to analyze the composition and types of hydrochemistry.Gibbs graph and correlation analysis are used to discuss the origin of hydrochemistry.The results show that:Na^+is the main cation in drinking water of concentrated deep groundwater in Fuyang City and the main anion is HCO^-3.Hydro-chemical types are generally HCO^-3-Na^+.Gibbs diagram and correlation analysis results show that,deep groundwater in Fuyang City is affected by both rock weathering and evaporation,evaporation is the main factor.In addition,changes in the external environment also have impact on the chemical composition of ionic water.
