中文摘要	详细了解干旱区地下水的补给机制对地下水资源管理来说是非常重要的,天然环境同位素在过去的40年里广泛应用于解决有关地下水补给、流动等问题。笔者通过分析酒泉张掖盆地水的环境同位素变化特征,识别地下水的补给和流动。研究结果表明,酒泉张掖盆地地下水的补给源主要来自山区出山河流,补给发生在祁连山前戈壁带,在山前冲积扇带地下水主要为1963年以来的快速补给,而部分深部地下水为1952年以前补给。同时,环境同位素指示盆地存在深部区域流系统和浅部局域流系统,酒泉盆地和张掖盆地之间不存在明显的水力联系。该研究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 and flow is vital for the proper management of groundwater resources in the arid area.Natural stable and radiogenic isotopes of water have been widely and extensively used over the last forty years to probe into problems related to the groundwater recharge and flow system.The present study aimed at the integration of a variety of isotopic measurements for analyzing the recharge and flow of the groundwater system in the Jiuquan-Zhangye Basin.The tracer data suggest that the recharge water of the basin is derived from the drainage of mountain rivers.Recharge to the aquifer occurs through the high permeability recharge zone in the piedmont area.Groundwater in the alluvial fan zone seems to be rapidly recharged water from the infiltration of mountain rivers since 1963,whereas some groundwater within the confined aquifers was recharged before1952.The tracers also indicate that there are two groundwater flow systems,i.e.,regional and local flow systems,and there are no significant hydrodynamic contact between the Jiuquan Subbasin and the Zhangye Subbasin.The common features established can not only serve as a case study but also contribute to the groundwater resource sustainable development in similar inland areas.
