研究目的：分析草地不同利用方式对土壤碳库的影响，为草地的合理利用提供参考。研究方法：文献资料法、实证分析法。研究结果：围封样地有机碳含量显著高于放牧及开垦样地，特别是在地表20 cm以上土层中。从各土层土壤有机碳的变化幅度来看，表层（0-10 cm）土壤有机碳变化幅度最大，围封样地为33.24 g·kg-1，过度放牧样地为21.19 g·kg-1，开垦样地为22.95 g·kg-1，过度放牧与开垦样地的土壤有机碳含量比围封样地降低了近1/3。研究结论：通过科学合理放牧制度的建立，退耕还草、加强人工草地的建设以及科学合理草地规划的编制等措施降低人为干扰，增强草地的碳汇能力。

The purpose of this paper is to analyze the impact of different ways of grassland use on soil carbon sequestration. Methods of literature review and empirical analysis were employed. The results indicate that the organic carbon sequestration in the fenced plot is significantly higher than the grazing and reclamation areas, especially in the soil layer of 20 cm above the earth surface. The impact of grassland use was much obvious in the surface soil layer, i.e., 0-10 cm. In detail, the organic carbon sequestration of fenced plot was 33.24 g·kg-1, that of the overgrazing plot was 21.19 g·kg-1, that of the reclaimed samples was 22.95 g·kg-1.The latter two were nearly 1/3 of the first type of land use. It is concluded that in order to reduce the impact of grassland uses on soil carbon sequestration, and to enhance the carbon sequestration ability of the soil it is necessary to establish a comprehensive institution on grazing, reclaim the overgrazed grassland, strengthen the construction of artificial grassland, and enhance the design of scientific and rational grassland planning.
