摘　　要：枯落物是草地生态系统的重要组成部分,其积累与分解对草地自肥、维持生态系统功能有重要作用。文章综述了目前草地枯落物研究方法、枯落物动态与环境的关系及其对土壤性质的影响研究;分析了枯落物在土壤碳库、草地水文及植被更新等方面的生态功能;为深入了解草地生态系统的结构和功能,保证草地生态系统的稳定和可持续发展提供理论指导。Litter is an important part of the grassland ecosystem, its accumulation and decomposition play an important role in grass rejected and maintaining ecosystem function.The present paper reviewed the current studies involving the research methods of grass litter,the relationship between litter dynamic and the environment, the effect of litter dynamic on soil properties and so on, to clarify the ecological function of litter on soil carbon pool,grass hydrology and vegetation update,etc.That can provide the oretical guidance for in-depth understanding of the structure and function of grassland ecosystem and ensuring the stability and the sustainable development of grassland ecosystem.
