Understanding the hydrogeochemical processes of carbonate aquifers is essential for utilizing local karst groundwater resources sustainability. Integrating hydrochemistry, environmental isotopes and hydrogeological conditions was used to study hydrogeochemical characteristics of a closed karst groundwater basin located in Shandong Province, North China. The dominant hydrochemistry type was HCO3–SO4–Ca in the karst groundwater system. Carbonates dissolution (especially calcite dissolution) as the main rock chemical weathering dominated the chemical compositions of the carbonate aquifers. Hydrogeochemical evolution processes of the closed karst groundwater basin were mainly carbonates dissolution accompanied with weak influences of human activities and weak evaporation during the recharging of atmospheric precipitation.
