In order to protect the four spring groups in Jinan, it is very important to study the formation characteristics of the karst spring in Jinan. Based on the geological and hydrogeological conditions of Jinan spring group outcropping area, this paper makes a comprehensive study on the karst aquifer void type, spring water supply source, spring water gushing state, spring water flow, spring water temperature and conductivity, spring water chemistry data in the recharging area, so as to determine the genetic types of four spring groups. The results are as follows: (1) Baotu spring and Heihu spring have a similar genetic structure, their circulation depth is relatively shallower, and they are greatly affected by Ordovician karst water in the direct recharging area. Tanxi spring and Pearl spring have a similar genetic structure with a deeper circulation depth, which are greatly affected by Cambrian karst water in the indirect recharging area. Tanxi spring and Pearl spring have a similar genetic structure with a deeper circulation depth, which are greatly affected by Cambrian karst water in the indirect recharging area; (2) Baotu spring and Heihu spring are long-running cold springs recharged by confined water, which belong to erosion rising spring; Pearl spring and Wulongtan are long-running large and medium-sized cold springs recharged by pressurized water, which belong to contact rising spring. The research on the genetic characteristics of spring provides a scientific basis for spring protection in Jinan.
