摘　　要：本文综述了目前的全球土壤碳储量、密度及其分布规律,从全球升温、大气CO2浓度增加以及气候变化引起土壤侵蚀加剧等几个方面阐述了土壤碳动态对全球气候变化的响应,并介绍了近年来国内外相关的一些研究成果。This paper deals with the global soil carbon storage, density and distribution laws at present, and illustrates the soil carbon responses to the climatic changes from several aspects： such as the increase of the global temperature, the addition of the CO2 concentration in the atmosphere and the intensification of soil erosion caused by climatic changes. In addition, some relevant research achivements at of home and abroad are also described in this paper.
