摘　　要：地下水系统的划分是正确评价黄河流域地下水资源的基础,该文阐述了黄河流域地下水系统划分的原则,即以地下水的循环特征和水力联系为依据,一级地下水系统以黄河一级支流流域分水岭为边界,二级系统主要考虑含水介质的类型(孔隙、裂隙、溶隙)以及黄河支流流域的分布。根据划分原则,将研究区分为9个一级地下水系统,31个二级系统,并论述了各地下水系统的主要水文地质特征。此外,该研究还对黄河下游地区和鄂尔多斯闭流区的地下水系统边界进行了讨论,认为在鄂尔多斯盆地北部地表闭流区内,同样存在有相应的浅层地下水闭流区系统;黄河下游地上悬河段,则充分考虑了黄河作为分水岭对两岸地下水的补给,即以黄河对地下水的补给范围作为地下水系统划分的边界;在入海口地区,从地下水的生态作用出发,进行了单独的划分。This paper focuses on the groundwater system division of the Yellow River Basin, which is the basis of accurate evaluation of groundwater resources. According to groundwater cycle characteristics and hydraulic relation, the principles of groundwater system division are presented in this paper: the first scale groundwater systems are on the boundaries of the first surface watersheds; and the second groundwater systems (subsystems) are divided on the basis of aquifer's mediums and the watersheds. The Yellow River Basin is divided into 9 first scale systems and 31 subsystems, whose main hydrogeological characteristics are described. Furthermore, the special boundaries of inner flow area in Erdos and the affected zone in the Down-Yellow River are discussed: 1) similar to the surface inner flow area in northern Erdos, there is of a groundwater inner flow area for the phreatic aquifer system; 2) in the affected zone of the Down-Yellow River, from the point of the river's influence, the boundary of groundwater system here is defined by the margin of the Yellow River's recharge to the groundwater; 3) the Yellow River Delta is separately divided as a groundwater subsystem for the sake of emphasizing the groundwater ecological problems in detail. The paper will provide theoretical foundation for evaluation of groundwater resources, study of groundwater renewable capacity, development and management of basin water resources in the Yellow River Basin.
