摘要
地下水在黑河流域水文过程和水资源转化中发挥着重要的作用。近20年来,研究者们专门针对黑河流域提出了一批地下水的数值模拟模型。这些模型在结构上可分为单层平面模型、双层准三维模型和多层三维模型。对包气带、河流与泉、开采井、季节性冻融等关键因素,现有模型采取了相似或不同的刻画方法,取得了一定的进展。未来的黑河流域地下水模型应加强与地表水、土壤水、水利工程等关联模型的耦合。
Groundwater plays an important role in the hydrological process and water resources transform in Heihe river basin. In the past two decades, a group of numerical models have been developed for the basin, which could be classified into three types according to their structures： Single-layer model （2D）, double-layer model （Quasi-3D） and muiti-layer model （3D）. The similar or different methods have been applied to deal with the key factors such as the vadose zone, rivers and springs, discharging wells, seasonal froze and thawing. Some of the methods perform well. It is suggested that the models used in future should improve their abilities of coupling with models subjected to surface water, soil water and hydraulic engineering.
