桂林寨底地下河水化学特征及离子来源分析
Analysis of hydro-chemical characteristics and ion resource from Zhaidi underground river in Guilin
摘要
Abstract
Hydro-chemical analysis is one of the main methods of underground river research.From Zhaidi under-ground river,the water samples were analyzed in August 2012 in wet season in addition to on-site measurement. Chemical analysis shows groundwater chemical type and salinity and hardness.It elaborates the characters of con-tent distribution of K +,Na +,Ca2 +,Mg2 +,HCO -3 ,SO2 -4 ,Cl - and the ion source.Two hydration analysis meth-ods that include ion ratio methods and principal component analysis study the ion source.The result indicates that ion sources come from carbonate dissolution and water rock interaction.The result shows Zhaidi underground river belongs to micro hardness,related to Ca2 +,HCO -3 .Water chemistry type is HCO3 -Ca,ion mainly comes from dissolution of carbonate rock,dolomite and human activity,with regularities of distribution.关键词
