摘　　要：查明地表水与地下水的转化关系是建立区域水循环模式、揭示水资源形成机制、评价水资源总量以及可持续开发利用水资源的必要环节。马莲河位于我国西北干旱半干旱气候区,流域内水资源时空分布不均,生态环境脆弱,水资源问题严重。受到区域气候、地质构造和自然地理环境的影响,河水与地下水的转化频繁、关系复杂。在分析了流域内地下水动力场特征的基础上,应用水化学方法和同位素技术相结合的方法分析了马莲河河水与地下水的相互转化关系。马莲河河水主要以接受地下水补给为主,仅在中游个别河段与地下水的水力联系较弱。It is the key work to determine the hydraulic relationship between surface water and groundwater for setting up the local water hydrologic cycle, opening out water resources forming-mechanism, evaluating water resources quantity and sustainably developing wafer resources, in Malianhe River catchment located in arid and semi-arid climatic zones, water resources are unevenly distributed in temporal and spatial with fragile ecological environment, therefore water resources problem become serious. Affected by local climate, geological structure and geographical environment, the interaction between river water and groundwater can not be understood yet due to the frequent and complex interaction. Therefore, the interaction of surface water and groundwater has been studied by hydrogeochemical and isotopic methods based on analyzing the characteristics of groundwater hydrodynamic field. Through the analysis, it can be known that Malianhe River water is dominantly recharged by the groundwater of Lower Cretaceous Huanhe aquifer except for minority section in the midstream where hydraulic connection between the river and the groundwater is weak.
