- 摘要:
- 利用水化学、氢氧同位素分析，结合研究区水文地质条件，阐述了研究区水环境特征，为工程建设提供了参考依据。水化学、同位素分析表明，该区地下水径流条件较差，水交替性弱；溶滤作用和蒸发作用对于该区地下水中各化学组分的形成有较大的贡献；大气降水和雪山融水为该区水体主要来源。以石英砾岩（P1）为界的双层含水系统，上部的风化裂隙水为就近的大气降水渗入补给，下部含水系统接受长距离运移的高山补给源补给。
- Abstract:
- Utilizing hydrochemistry analysis and oxygen and hydrogen isotope analysis, integrating with hydrogeologic condition, the water environment of study area is described and reference to engineering construction is provided.From the results of hydrochemistry and isotope analysis, it can be seen that the groundwater runoff condition and the water alternate condition is relative bad, the dissolution or precipitation and evaporation has great contribution to the formation of each groundwater chemical constituent and the main source of water in this area is precipitation water and ice-snow molten water.The two aquifers are divided by quartz conglomerate (P1).The upper weathering crevice water are recharged by precipitation water.The under aquifer accept alpine recharge by long distance moving.
