摘　　要：研究区域地下水的水化学特征、水文地球化学过程对地下水开发利用及保护有着重要的意义。运用离子比值法结合水文地质条件对新疆巴里坤县汉水泉洼地承压水中的主要离子比值变化特征进行了分析,并用单因子评价法对汉水泉洼地承压水质量进行评价。结果表明:汉水泉洼地承压水沿地下水流向,水动力条件逐渐变差,水交替程度逐渐变弱,总溶解固体逐渐升高;汉水泉洼地承压水不是海相沉积水;汉水泉洼地承压水质量属于Ⅴ类,水质较差。Study on regional groundwater chemical characteristics and hydrogeochemical processes are of great significance on exploitation and protection of groundwater. We analyzed the changes of the main ions ratio in confined groundwater in Hanshuiquan depression of Balikun Country of Xinjiang by ion ratio method combined with hydrogeological conditions. Confined groundwater quality of Hanshuiquan depression were assessed by single-factor assessment method. Results showed that hydrodynamic condition of the confined groundwater belong groundwa- ter flow direction gradually becomes poor, groundwater exchange intensity gradually becomes weaker, total dissolved solid gradually increased in Hanshuiquan depression. Confined groundwater in Hanshuiquan depression is not marine deposit groundwater. The confined groundwater quality ranks in class V, the confined groundwater quality is worse in Hanshuiquan depression.
