摘　　要：地下水系统是水文地质学的研究热点之一。学术界对"地下水系统"的概念尚没有明确和统一的认识,不同学者对"地下水系统"的理解各有侧重,划分依据与标准不一,划分结果各异,故在应用上常造成混乱。文中基于地下水流系统的概念,归纳了地下水系统划分的原则和依据,认为地下水系统划分应以自然状态不同级别的地下水流系统为首要依据,以含水层系统为判断水力联系和流动系统内部结构的重要基础,提出了一套划分中国北方地下水系统的方案,将其划分为4个地下水系统区块、10个一级地下水系统和56个二级地下水系统。地下水系统区块主要依据特大区域尺度上具有相似地下水循环特征且在地域上毗邻的盆地(流域)的组合体划分:一级地下水系统主要依据盆地(流域)尺度的区域地下水流系统和区域地下水流向划分;二级地下水系统主要依据区域水流系统的分区特征(受次级盆地或次级流域控制)划分。这一方案为中国北方区域地下水资源评价、地下水资源管理、地下水与环境等相关问题的研究提供地下水系统的框架基础。Groundwater system is a research hotspot in hydrogeology.There is no clear definition and unified understanding of its meaning in academia till now.Different scholars put different emphases on the understanding of the concept and divided the groundwater systems according to different criteria,leading to the different results,which have caused the confusion in its application.Based on the concept of groundwater flow system,a clear concept of the groundwater system was redefined.We summarized the principles and bases of the groundwater system division;the primary division basis is groundwater flow system（different levels）under natural conditions;and the important foundation for judging hydraulic connection and internal structure of groundwater flow system is the aquifer system.In this paper,we put forward a scheme of groundwater system division in northern China,and divide it into 4groundwater areas,10first scale systems and 56subsystems.The division of the groundwater areas is mainly based on the combination of adjacent groundwater basins which have the same characteristics of groundwater circulation at a large regional scale;the division of the first scale groundwater systems is based on the regional groundwater flow system and groundwater flow direction;and the division of the subsystems is based on the subarea of regional groundwater flow system,which are affected by subbasins.The results provide a scientific basis for the evaluation and management of the regional groundwater resources,and a research frame for groundwater and environmental issues in northern China.
