摘　　要：综合统计分析了水源地的水化学特征,运用Piper三线图、Schoeller图、Gibbs图、离子关系图等方法,对研究区的地下水主要组成成分进行了分析研究。结果表明:水源地地下水总体呈弱碱性;主要阳离子为Ca^(2+)和Mg^(2+),阴离子为HCO_(3-)和SO_4^(2-);地下水化学类型主要为HCO_3.SO_4-Ca.Na型;岩石风化及水岩作用是地下水水化学类型形成的主要控制因素,地下水中化学组分主要来源于碳酸岩矿物的风化和水岩作用。Analysis of mineral groundwater samples taken from a groundwater sources in Tibet was carried out firstly.And then the descriptive statistics,Pearson correlation matrices,the Piper diagram,Schoeller diagram,Gibbs diagram and the ratio coefficient of the main ions were used to analyze the hydro-chemical characteristics and causes of groundwater in the area.Following results were obtained:the groundwater quality present weak alkalinity.Ca 2+,Mg 2+,HCO-3 and SO 2-4 are major ions in groundwaterand the major hydro-chemical types are HCO 3,SO 4-Ca and Na.Rock weathering and water rock interaction are the principal factors that control the groundwater hydro-chemical type formation mechanism.The main components in groundwater are gradually formed by these two processes.
