| 摘 要： | 在大量的实测资科和参考资料的基础上,运用地球水化学分析、地质构造理论和同位素方法,探讨了该地区地下水化学组分的特征以及矿化度与各组分含量之间的相互关系,并对其水化学特征的形成机理进行了深入分析,认为该地区地下水有深部构造水和浅层地下水两种类型,这种组成特点与区内地质构造存在必然联系;地下水同位素等分析显示,该地区地下水的补给主要为现代大气降水及雪山融水,浅层水为就地补给,深部构造水为高山远距离运移补给;地下水化学组分的成因主要是溶滤作用和蒸发作用。

| Abstract: | In terms of geochemical analyses,geologic structure and isotopic theory, the paper analyzes the hydrochemical characteris tics of groundwater in the Zhangla Basin, northwestern Sichuan and water chemical compositions, based on a lot of on-the-spot surveying data and reference material, and profoundly studies the formation mechanism of hydrochcmical characteristics of groundwater in the region. It is considered that groundwater in the region consists of deep structure groundwater and shallow groundwater, which have the necessary relation with the regionally geologic structure. The isotopic composition of groundwater shows the recharge is dominated by modern meteoric water and ice-snow molten water. The major factors affecting the chemical composition of groundwater are dissolution or precipitation and evaporation. |
