摘　　要：森林凋落物是陆地生态系统的重要组成部分,它影响土壤有机质的形成,植物养分的供应,以及土壤碳的吸收和储存。通过对相关文献的查阅,从凋落物量动态、凋落物分解,以及凋落物持水性等方面分析了森林凋落物的特性。其中凋落物分解受到很多因素的影响,如气候、凋落物质量及土壤动物等因素。通过整理相关研究成果,综述了森林凋落物输入不同处理对土壤团聚体以及土壤有机碳储量的影响。Forest litter is an important part of terrestrial ecosystem,which affects the formation of soil organic matter,the supply of plant nutrients and the absorption and storage of soil carbon.By consulting the relevant literature,the characteristics of litter were analyzed from the aspects of litter dynamics,litter decomposition and litter water holding capacity.Among them,litter decomposition was influenced by many factors,such as climate,litter quality and soil animals.The effects of different treatments of forest litter input on soil aggregates and soil organic carbon storage were summarized by sorting out relevant research results.

关 键 词：森林凋落物 土壤团聚体 土壤有机碳
