The research degree of karst groundwater in Jinan area is high. But there are more disputes in the spring field boundary and system name. As the unified ideological understanding,setting groundwater system theory as the guidance,and based on the principles of the boundaries and name,Jinan monoclinic karst water system is divided into a threelevel system. The boundaries of the system are clearly defined at all levels. Through analyzing main tectonic hydrogeological characteristics, hydraulic connection and drainage relationship between typical spring fields have been studied. Through comprehensive study on karst groundwater system division and hydraulic connection, geological basis can be provided for spring protection and water supply in Jinan city.
