在参考大量相关文献的基础上,对我国森林生态系统枯落物现存量研究进展进行了归纳总结。我国枯落物现存量的研究主要集中在亚热带和温带,热带相对较少;枯落物现存量的研究主要采用收获法,但取样样方的布设、面积、数量及取样时间等尚没有统一的规定;在大区域尺度上,气候是影响森林枯落物现存量变化的主导因子,不同气候带森林枯落物现存量的大小顺序为温带>亚热带>热带;森林枯落物现存量还受林分起源、群落组成和结构、群落发育阶段、土壤、地形条件及干扰的影响。文中还针对全球变化背景下我国森林枯落物现存量研究中存在的问题及今后的研究方向进行了探讨。
On the basis of a large number of related literatures, this paper summarizes the research progress of the existing stock of forest litter in our country. The studies on the existing stock of litter in China mainly focus on the subtropical and temperate regions with relatively few tropical species. The research on the existing stock of litter mainly uses the harvesting method. However, the layout, area, quantity and sampling time of the sampled species are not unified The climate is the dominant factor that affects the change of the existing stock of forest litters. The order of abundance of forest litters in different climatic zones is temperate zone> subtropical zone> tropical zone. The existing amount of forest litter is also affected by forest Sub-origin, community composition and structure, community development stage, soil, topographical conditions and interference. The paper also discusses the existing problems in the study of forest litter in the context of global change and the future research directions.
