【Abstract】 Land use change is still a major source of carbon dynamics emission due to burning and cultivation,which caused to decline soil organic carbon contents in soils and degrade soil quality.The effects of cultivation on soil organic carbon dynamics in agroecosystems were reviewed in this paper based on the research results and recent advances in this field.Some future directions in the Black Soil Region of China were presented.更多还原
