中文摘要	中国西北属于干旱区,区域内发育有很多内陆河。在内陆河流域,地表水与地下水之间的转化十分明显。为探索干旱区地表水对地下水的转化特征,以便为有效开发利用水资源和预测地下水环境变化提供理论依据,本研究以塔里木河下游为研究区,对不同河段的河水与地下水进行了取样,并利用同位素技术研究了地表水对地下水的转化比率。结果表明:在塔里木河下游地区,河水向地下水的转化明显,阿拉干断面河水向地下水转化率最高;总体而言,沿河道向下游,河水向地下水的补给量呈减少趋势;本文运用质量守恒原理,并通过定量分析,得出塔里木河下游河水向地下水的平均转化率为43.36%,这对于合理利用区域内的水资源、正确评价生态输水效益具有重要意义。
英文摘要	Northwest China belongs to the arid region,and there are many inland rivers in the region. There were frequent conversion relationships between surface water and groundwater in inland river basin. In order to explore the characteristics of transformation between surface water and groundwater,so as to provide theoretical basis for effective development and utilization of water resources and prediction of groundwater environment changes,the lower reaches of Tarim River was taken as the study area,and the river water and groundwater in different sections were sampled. What’s more,conversion ratio of surface water to groundwater has been studied using isotope technology. Results show that: in the lower reaches of the Tarim River,conversion of river water to groundwater was remarkable,and the conversion ratio at Alagan section was the highest. In general,recharge of river water to groundwater presented a decrease trend along the river from upstream to downstream. Based on principle of mass balance and according to quantitative analysis,the average conversion ratio of river water to groundwater was 43.36%. This provides the foundation for evaluating ecological water conveyance efficiency correctly and is also helpful for rational utilization of water resources.
