Abstract: A large amount of soil organic carbon (SOC) was transported, transformed and lost by soil erosion, which can resulted in serious environmental problems, so soil erosion was considered as an important environmental hazard. Relative mechanism was still uncertain. Effects of water erosion and wind erosion on SOC and CO2 were illuminated. SOC was also affected by the change of land use such as forestry to farmland or grassland and grassland to farmland, and zero tillage can improve soil carbon sequestration. Measures that can control erosion and reduce the loss of soil carbon were put forward.
