- Abstract:
-
Soil carbon loss is a never-ending process, however, soil erosion, the most dominantly driving force, deeply influences carbon cycle in the terrestrial ecosystem, which will contribute to the understand of the carbon budget and make relative policy under global climate change. The recent advances of related researches about water erosion and wind erosion were reviewed, the mechanism of soil erosion process as well as a discussion of main problems of ’source or sink’ existing in dynamic process of erosion were made, on-site and off-site environment effects were also summarized, and meanwhile, based on above analysis, the realistic questions and main research directions were brought forth for research in this field in the future. In the erosion process, carbon sequestration and loss existed simultaneously, carbon lost in the form of sediment transfer and soil respiration. Currently relative researches focused on the fate of eroded SOC. To reveal the relation of import and export of soil carbon and evaluate the influence of erosion on carbon loss and regional carbon cycles will be the urgent scientific issues in the future.
