Abstract: Soil carbon pool is the largest carbon pool in terrestrial ecosystems. It plays a very important role in regulating global climate change and ecosystem carbon cycle. Soil inorganic carbon(SIC) is the second largest carbon pool in the soil, second only to soil organic carbon(SOC),which mainly exists in arid and semi-arid areas. In this paper, the distribution and influencing factors of soil inorganic carbon, the mechanism of soil carbon sequestration and the application of carbon stable isotope technology are discussed,aiming to emphasize the role and status of soil inorganic carbon in global climate change and carbon cycle. We should strengthen the research on the role of soil inorganic carbon in terrestrial ecosystem, and deeply explore the cycling process of soil inorganic carbon, so as to provide reference for correctly determining the carbon source and sink function of terrestrial ecosystem.

Key words: soil carbon pool, soil inorganic carbon, secondary carbonate, stable isotope
