摘  要:
草地是我国重要的土地利用类型之一,草地生态系统有机碳库是全球碳循环的重要组成部分,其积累和分解的变化直接影响全球的碳平衡,研究草地土壤有机碳库的影响因素,对于准确评估我国草地生态系统的固碳潜力具有重要的科学意义。该研究在对现有资料整理的基础上,着重综述了自然因子、人类活动以及气候变化等因素对草地土壤碳储量影响的国内外研究进展,指出了目前草地土壤有机碳研究存在的问题,探讨草地固碳对外界因子的响应机制和适应对策,提出了草地土壤碳储量影响因素研究的发展趋势,并对今后草地土壤有机碳研究进行了展望。

摘  要:
Grassland is one of the important land use types in China.Grassland ecosystem organic carbon pool is an important component of the global carbon cycle,which directly affects the accumulation of decomposition to global carbon balance.Influence factors for grassland soil organic carbon pool has important scientific significance for the assessment of carbon sequestration potential of grassland ecosystems.In this study,this paper focused on the natural factors,human activities,climate change and other factors affected the domestic and international research of grassland soil carbon reserves in progress,pointed grassland soil organic carbon study existing problems and discussion on grassland carbon fixation mechanisms and adaptation strategies in response to external factors.Besides,this paper made a grassland soil carbon storage factors research trends and prospects for the future study of grassland soil organic carbon.
