A Review of Researches on Forest Litterfall

The paper give an overall introduction to the concept of forest litterfall, ecological function, methodology, influencing factors of litterfall and the composition of forest litter. The results showed that the litterfall was influenced by the climatic factor such as temperature, precipitation and the length of the vegetation growing season, but the leading influencing climatic factor was annual mean temperature. This paper mainly study fallenwood, death rootsystem、forest litter fallin broadsense. The research method, physical and chemical processes of Litter decomposition, influence factors of Litter decomposition and dynamic process of decomposition and nutrient release, which are all reviewed in research progress, Deriving research progress of Litter fall in forest ecosystems and elucidating dynamic study of litter currently through Longitudinal compare. The research and development direction of litter fall are discussed, summarizing the existing problems simultaneously.
