地下水是玛纳斯河流域主要的供水水源，为宏观掌握该区地下水化学特征，了解区域地下水主要形成过程，运用舒卡列夫分类法、数学统计法、吉布斯图、离子比及同位素的方法，在分析玛纳斯河流域平原区典型剖面的地下水水化学常量组分、吉布斯图、离子比和同位素特征的基础上，进行了研究区水文地球化学特征研究。结果表明：研究区潜水和承压水水力联系紧密；从上游、中游到下游，潜水、承压水的δ18 O、δD值逐渐增大。地下水形成主要受蒸发浓缩、大气降水及碳酸盐岩和硫酸盐岩的溶滤作用。

Groundwater is main source of water supply in Manasi River Basin.In order to understand groundwa-ter hydrology characteristics and main process of groundwater formed,hydro-geochemistry in Plain of Manasi River Basin is studied according to the analysis of constant chemistry component,Gibbs graph,ion ratio and i-sotopic characteristics of groundwater in typical profile using the method of Shukaliefu classification,mathemati-cal statistics method,Gibbs graph and ion ratio.It is found that unconfined water and confined water have a close hydraulic relationship.The values ofδ18 O and δD are increase from upstream to downstream.Hydrolysis process occurring in groundwater systems which decided the chemical characteristics of research area,includes evaporation concentration,precipitation and lixiviation of carbonate rock and sulfate rock.
