摘要
Carbonate rocks, as soluble rocks, will dissolve and experience karstification driven by flowing water. This process consumes CO2from the air and converts atmospheric CO2and CO32-of rocks into HCO3-, resulting in the transfer of carbon from the atmosphere to the hydrosphere. Part of those dissolved HCO3-in the groundwater and surface water will degrade as CO2and return to the atmosphere.Furthermore, some HCO3-will be utilized by aquatic photosynthetic organisms to be converted into organic carbon,
