Taking the Dagouhe Basin in Guangxi as a study area, the influences of land covers on carbon sink of underground rivers on both the east and west banks are analyzed. The forest land and farmland respectively occupy 56.3 % and 15.15 % of the total area on the east bank, but in the west bank they only respectively occupy 20.8 % and 12.95 % of the total area. The differences of land covers on the east bank and the west bank of the Dagouhe lead to a lot difference of geochemical indexes in the carbon cycle of the underground river between the two banks are lower than that on the west bank, 0.38 and 7.85, respectively. Therefore, there are stronger karst dynamic conditions on the east bank. That is why the mean carbon sink intensity of the underground river on the east bank is 14% higher than that on the west bank.oft-com:office:office" />
