Atmospheric CO2 can be absorbed and dissolved in water among karst processes, not only occurred in the carbonate rock area but also in all other rock areas of the global continent. Therefore, the previous cal- culation data of the karst carbon cycle based on the carbonate area is less and should be calculated again based on all river basins in the world. Besides the dissolved inorganic carbon of the rivers into oceans, the carbon sink of karst processes can be formed in particulate organic carbon of waters deposited by aquatic vegetation and the karst soil organie earbon etc. many carbon sequestered fashions. Among them,only the particulate organic carbon of waters deposited by aquatic vegetation absorbed from bicarbonate ions can reach about 0.5 Gt. The ecological rehabilitation can promote the organic earbon fixed in karst soils and inorganic carbon sink of water in the basin. As a result, the treatment engineering of the rocky desertification in southwest China at least can raise karst carbon sink 0.2 to 0.3 Gt. If the carbon sequestered technology in karst proces- ses is considered and applied in ecological rehabilitation of the world, the global carbon sink effects should be very evident.
