草地生态系统碳蓄积的研究进展

The research progress of carbon storage in grassland ecosystem

介绍了全球碳循环与全球气候变化下草地生态系统碳蓄积研究的进展,并对世界和中国草地生态系统在陆地生态系统碳储量、碳循环及在全球气候变化中的地位和作用进行了分析。同时,对草地初级生产力、土壤有机碳、枯落物、放牧利用、草地开垦等因素影响草地生态系统碳蓄积的研究进行了评价,提出了中国草地生态系统碳蓄积研究需解决的主要问题和研究前景。

The paper introduced the research progresses of carbon accumulation in grassland ecosystem. The carbon storage, carbon cycle in grassland ecosystem and its role in global climate change were discussed. The factors affecting carbon stock in grassland ecosystem were evaluated, including primary productivity, organic carbon in the soil, plant litter, grazing and cropland exploitation. The main problems need to be resolved in the research of carbon stock in grassland ecosystem were pointed out.
