Abstract

Soil organic carbon releases CO2 at the aeration status, which results in greenhouse effect and consequently influences global change. Currently sequestrating CO2 to agricultural soil is a front field in soil carbon cycle studies, among which whether agricultural soil redistribution leads to carbon sequestration has developed scientific,political and social interests. In this paper, the effects of soil redistribution on soil organic carbon in multi-scales are discussed. The significance of soil erosion and redeposition in the study of terrestrial carbon cycles, the relationship between soil redistribution and the missing sink, and the mechanism of carbon sequestration resulting from soil redistribution are expounded. Based on above analysis the stringent problems needed to resolve are put forward.
