利用δ（^18O）和δ（D）资料对黑河流域的冰雪融水、地表水、地下水的氘过量参数（d值）特征的研究结果表明：①黑河流域源区祁连山区冰雪融水的d值特别偏正，为16．0‰～24．8‰；②张掖盆地细土平原浅层地下水的d值（9．0‰～12．0‰）与深层地下水的d值（16．6‰～21．8‰）表现出明显的差异性，指示着不同的补给来源，浅层地下水主要由大气补给，深层地下水反映出冰雪融水补给的特．苣；酒泉盆地浅层和深层地下水的d值接近（介于15．8‰～19．6‰间），主要以山区冰雪融水和基岩裂隙水补给为主；③额济纳盆地大部分浅层地下水的d值介于2．6‰-8．8‰间，受到了一定程度的蒸发作用，这是干旱地区地下水的特殊特征；④古日乃地区地下水的d值特别偏负，达～30‰左右，这种现象在全球极为罕见；⑤东居延海地区附近的深层承压水的d值（～2．4‰～1．0‰）也表现出了一定的特殊性，表明该区地下水是在较寒冷的气候条件下形成的；⑥东居延海地表水和天鹅湖湖水的δ（^18O）和δ（D）均为正，远大干了海水的氧氚值，而且d值异常偏负，达-55．2‰～-35．8‰，这可能是极度干旱的环境下地表水过度蒸发的结果。研究揭示了流域水循环转化过程中和大气降水、冰雪融水、地表水、地下水之间的相互关系及其作用，为流域水资源管理和生态环境保护提供了有意义的信息。

英文摘要：

Deuterium excess parameter（d value）is of considerable hydrogeological significance, for it is an important parameter index in the study of surface water and groundwater. Heihe River, with fragile ecological environment, is one of largest interior rivers in the arid northwest region of China. Hence, the study on the characteristics of deuterium excess parameter about snow melting water, surface water and groundwater in Heihe drainage area will help to reveal the interrelation and interreaction with precipitation, snow melting water, surface water and groundwater during water cycle and transformation in the area and can provide useful information for protecting ecological environment and managing water resources. The research shows that： （1） the d value of snow melting water in Qilian Mountain, the source region of Heihe River, is specially much positive and reaches up to 16.0‰-24.8‰; （2） the d value has visible difference between shallow groundwater and deep groundwater in fine soil plain of Zhangye Basin, respectively 9.0‰-12.0‰ and 16. 6‰-21. 8‰, showing the different recharge resources. The d values of shallow and deep groundwater are both between 15.8‰ and 19.6‰ in Jiuquan Basin, where groundwater is mainly recharged by snow melting water and bedrock fissure water; （3） most shallow groundwater in Ejina Basin is influenced by evaporation, with d values of 2.6‰-8.8‰, which is the unique characteristic in the arid area; （4） the d value is more negative lowly to about -30‰ or so in Gurinai area, which is infrequent in the world, where the groundwater may be supplied by meteoric water in conditions of cold climate and be vaporized during slow flow for longtime; （5） the special was also found in deep groundwater near east Juyan Sea, with d values of -2.4‰- -1.0‰, showing that groundwater may be formed in cold climate; （6） the surface water in east Juyan Sea and Swan Lake has both positive values of δ（^18O） and δ（D）, far exceeding the seawater.
