Abstract：Guanzhong Basin has a groundwater system with complete hydrogeological structure, relatively independent water system and open water cycle. This paper introduces the regional hydrogeological structure and characteristics of groundwater cycle. Based on the textural association and distribution characteristics of groundwater aquatic media and the characteristics of groundwater circulation, the groundwater system in Guanzhong Basin is divided into six categories: pore-fractured water system in loess terrace like plain, pore water system in alluvial plain, pore water system in aggraded flood plain, water system in Weibei karst, Neogene and Paleogene pore-fractured water system in sand and mudstone interbedded fracture, and fracture water system in bedrock. Also the water-richness, bucket diameter, hydrochemistry and dynamic characteristics for each aqueous system are summarized. The purpose of this paper is to provide a basis for the objective evaluation of the current situation of water resources in Guanzhong Economic Zone, and for the optimal allocation of water resources, development and utilization and protection programs, which is of great significance to the construction of good and livable ecological environment and sustainable economic development.
