Carbonate rock is the basic material of karst ecosystem, and its formation in geological era has an important role on the atmospheric CO2 decreasing, about 99.5％ of the carbon in the earth is sealed in carbonate rock;Karst ecosystem is characterized as rich calcium, alkaline, impacting carbon cycle: carbonate rock is the sedimentary rock deriving from clean ocean, its acidic insoluble matter is usually less than 10％, which lead shortage of the soil resources in karst area, therefore the total amount of limestone soil carbon in karst area is small.
