大气CO2浓度R升高引起全球气候变暖，因此，陆地生态系统碳固存已经受到世界各国科学家的普遍关注。作为世界上植被类型分布最广的草原，既是重要的生态安全保障，又是重要的碳汇资源库。然而，长期以来人们仅注重了它承载牲畜的作用，但草原生态系统的碳储藏能力仅于森林，其能抑制温室效应。通过从草原生态系统的碳汇功能，草原生态系统固碳能力和高寒草地生态系统面临危机3个方面论述了草原的碳汇功能不容忽视。因此，开发碳汇草业价值，发挥我国草地生态系统的功能，特别是加强高寒草甸草原资源保护，将会对全球碳的保存、CO2的减排具有极其深远的意义。

Under the background of global climate warming caused by increasing concentration of CO2 in the atmosphere, the potential to sequestrate carbon for the global terrestrial ecosystems has received universal concern from the scientists over the world. Grassland possesses the richest vegetation types and plays important roles in both ecological security and carbon sequestration. However, people only pay attention to its capacity for grazing in a long time. The capacity of carbon storage of grassland ecosystem is only lower than forest and it can largely limit the greenhouse emission.
