| 摘 要： | 土壤侵蚀是重要的环境公害，侵蚀造成土壤有机碳的大量迁移、转化和流失，产生严重的环境问题，相关机理研究尚不清楚。本文阐述了水蚀和风蚀两种主要方式对土壤有机碳库的影响，侵蚀和二氧化碳温室气体排放的关系。介绍了林地转为农田、草地以及草地转为农田等土地利用方式的改变对土壤有机碳库的影响，免耕提高土壤固碳能力。提出了控制侵蚀，减少土壤碳流失的措施。

| 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. |

| Keywords: | Soil organic carbon(SOC) Soil erosion Land use Measures of prevention and control. |
