摘　　要：凋落物是陆地生态系统的重要组成部分,在陆地生态系统中,凋落物不仅是土壤有机质的重要来源之一,而且还是连接土壤和植物之间的桥梁。凋落物通过淋溶、分解等过程对土壤养分产生影响,同时,凋落物也是土壤微生物的主要碳源。本文通过对相关文献的查阅,从土壤酶活性、土壤微生物生物量、土壤微生物群落结构以及土壤微生物功能多样性等方面分析了凋落物多样性对土壤微生物特性的影响,以期能够更好的利用凋落物,为维持土壤肥力提供保障。Litter is an important part of terrestrial ecosystem.In terrestrial ecosystem,litter is not only one of the important sources of soil organic matter,but also a bridge between soil and plants.Litter affects soil nutrients through leaching and decomposition,and it is also the main carbon source of soil microorganisms.By consulting the relevant literature,this paper analyzed the effects of litter diversity on soil microbial characteristics from the aspects of soil enzyme activity,soil micro bial biomass,soil microbial community structure and soil microbial functional diversity,so as to make better use of litter and provide guarantee for maintaining soil fertility.
