四川省泸沽湖地区地下水水化学特征研究

On underground water chemical characteristics in Luguhu area Sichuan province

通过研究区的泉点、地表水的水化学组成、氢氧同位素分析,结合水文地质条件,阐述了研究区地下水环境特征,分析表明,研究区地下水化学类型以HCO3-Ca,HCO3.Cl-Ca.Na为主,大气降水为该区各水体主要补给来源。

According to analysis on spring point of the research area,water chemical composition of the underground water,and the hydrogen oxygen isotopes,it combines with hydrogeology condition,describes underground water environment characteristics in the research area,analysis proves that the water chemical type of the underground water in research area mainly is HCO3-Ca and HCO3·Cl-Ca·Na,and the meteoric water is the main water supply resource of this area.
