中文摘要	本文利用稳定同位素(2H和18O)及水化学方法识别黑河流域地下水的补给来源,估算黑河水与地下水的转化数量.研究结果表明,黑河流域地下水的主要补给来自山区出山河流,山前戈壁带是地下水快速补给区,中下游盆地地下水补给来源为引河灌溉和河流侧渗.黑河干流出山河水在张掖以上河段约4.410~8 m~3/a渗漏补给地下水,约占出山迳流量的27%.张掖一正义峡河段道地下水向河道平均排泄量为11.410~8 m~3/a,占该段河流迳流量的69%.研究成果不仅对黑河流域地下水的开发管理有着重要意义,对我国西北类似的内陆盆地地下水的开发管理有着借鉴意义.
英文摘要	Detailed information on groundwater recharge is vital for the proper management of groundwater resources in arid areas. The present study is to clarify groundwater recharge mechanism by using isotopes (H, H, O)and chemical measurements in the Heihe River basin, and estimate groundwater exchange with the Heihe River using water budget and isotope mass-balance approaches. The tracer data suggest that recharge source to the aquifers was from a series of ephemeral or perennial mountain streams. Recharge occurs directly by rapid infiltration in the piedmont of the Qilian Mountains. Infiltration from river and irrigation mainly occurs in the riverside and agricultural area. The delta~(18)O and (D values are high and show a strong isotopic evaporation before recharge. River infiltration into the aquifers along the intervals between Yingluoxia and Zhangye is 0.44 * 10~(-9)m~3/a (27% of the river discharge), and groundwater inflow into the river along the intervals between Zhangye and Zhengyixia is 1.14 * 10~(-9)m~3/a (69% of the river discharge). The common features established in this paper is significant not only in the Heihe basin but also in the similar inland areas in northwest China.
