在西北干旱区内陆河流域，地表水与地下水转化频繁，流域内河流和含水层之间的相互作用历来是水循环研究的关键环节。环境同位素作为水循环研究中的示踪剂，可以有效地揭示流域河流-含水层之间的转化关系。根据张掖盆地黑河河水及其两岸地下水中的稳定氢氧同位素资料及氘过量参数（ d）值，分析了张掖盆地内不同水体中的δD、δ18 O和 d值的分布规律及其所指示的地下水主要补给来源和地下水与黑河河水的相互作用关系。结果表明，张掖盆地内地下水和地表水同源于山区的降水和冰雪融水，不同深度地下水之间的水力联系密切，为统一的河流-地下水系统。在张掖盆地灌溉区，绿洲农田灌溉严重影响了地下水和河水之间的转化，导致地下水补给地表水的增加。运用质量守恒原理，定量分析了盆地地下水与地表水转化的转化量，为正确评价和合理利用水资源奠定了基础。

In the arid inland river basin of western China ,groundwater and surface water exchange frequently ,and the interaction between the river and aquifer in the river basin is an important research aspect of water cycle .Environmental isotopes can effec-tively reveal the relationship between the river and aquifer as tracers in the water cycle .Based on the environmental isotope fea-tures of hydrogen ,oxygen ,and deuterium excess (d) in groundwater and Heihe River of the Zhangye Basin ,the spatial charac-teristics of δD ,δ18 O ,and d in different water bodies were analyzed ,which may indicate the main sources of groundwater and the interaction between groundwater and Heihe River .The results indicated that the groundwater and river water are mainly derived from the snow milting water and rainfall and the hydraulic connection of groundwater in different depths is very high .In the ir-rigation area of the Zhangye Basin ,flood irrigation on vast farmlands has caused significant impacts on the interaction between groundwater and river water ,resulting in the increasing of groundwater recharging river water .The exchange between groundw-ater and river water was analyzed quantitatively using the mass conservation principle ,which can provide scientific basis for ac-curate assessment and reasonable utilization of water resources .
