Abstract: Soil organic carbon is a key component of global carbon cycle,and its storage and stability are strongly influenced by human activities.Human activities affect directly or indirectly the reduction of carbon storage in soil.This review summarizes the losing pathways of soil organic carbon and concerning research progress.On the one hand,land use and management will turn wetland,forest,grassland and other lands with high organic matter content into farmland,therefore reducing soil carbon sequestration capacity directly.On the other hand,climate change can increase soil carbon flux,affecting indirectly the loss of soil organic carbon.Considering both direct and indirect influences is of great significance for the study of soil carbon pool.It is proposed that it will be very effective to maintain soil carbon storage by promoting a series of land use/coverage change measures such as returning farmland to forest,returning grazing to grass and wetland protection.
