碳主要在通气状态下释放出CO2以温室效应的形式影响全球变化。当前，农田土壤固碳过程是土壤碳循环研究中的一个前沿领域，其中农田土壤再分布过程能否导致土壤固碳已引起科学上、政治上以及社会上广泛的兴趣。本文从不同的尺度阐述土壤再分布过程对土壤有机碳的影响。分别阐述土壤侵蚀和再沉积过程在全球碳循环，陆地碳库研究中的作用，土壤侵蚀与农田景观土壤有机碳动态、活性组份以及碳通量之间的关系，土壤再分布过程引起的土壤固碳机理。在此基础上指出今后迫切需要解决的问题。

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.
