In order to ensure the efficient and reasonable utilization of groundwater and the sustainable development of groundwater systems in Jinan City, a hydrogeological survey was conducted in the study area of the spring area, collecting groundwater dynamic observation data over the years, and sampling and testing the water chemistry of the spring water. The characteristics of spring water flow and spring water chemical dynamics comprehensively summarize the spring water dynamics. Research shows that besides the influence of precipitation, the water level of Baotu Spring is also affected by the discharge of Wohushan Reservoir and various recharges, especially artificial supplementary measures have played a certain role in maintaining the water level attenuation of Baotu Spring during the dry season; The change law of spring water flow and groundwater level is the result of the combined effects of direct recharge of atmospheric precipitation, indirect recharge of river leakage, and groundwater excretion; due to the influence of human activities, the conventional ion composition of spring water has an upward trend. The research results provide technical basis for spring water protection.
