Abstract: 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.
