摘　　要：Carbonate rocks, as soluble rocks, will dissolve and experience karstification driven by flowing water. This process consumes CO_(2)from the air and converts atmospheric CO_(2) and CO_(3)^(2-)of rocks into HCO_(3)^(-), 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 CO_(2) and return to the atmosphere.
