Abstract: From the viewpoint of the globe and ecosystem,this paper reviewed the effects and the possible action mechanisms of plant process on soil organic carbon concentration.Plant process could affect the source and sink of soil organic carbon,which was likely related with ambient temperature,and forest process could be in favor of the accumulation of soil carbon.Future tasks in this field were put forward to reduce the CO2 concentration in atmosphere through controlling the respiration of soil surface layer and keeping ecosystem balance.It is crucial to make efforts in increasing plant biomass to enhance soil organic carbon storage.

Key words: Soil organic carbon, Plant process, Ecosystem
