摘要：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。
In this paper, the authors summarized and concluded the research progress in litter accumulation of forest ecosystem in China based on literature review. The results showed that the current researches of litter accumulation are mainly focused on subtropical and temperate forests, with little attention put to the researches on tropical forests. Harvest is the main research method adopted now, but there is no unified standard for the quadrant layout, area and quantity as well as for sampling time. In a large scale, climate is the leading influencing factor affecting litter accumulation in forest ecosystems, and litter accumulation in forest of different climatic zones could be ordered as follows ： temperate forest 〉 subtropical forest 〉 tropical forest. Forest litter accumulation is also influenced by origin, community development, community composition and structure, soil, terrain condition and interference. This paper also discussed the problems found in the research on forest litter accumulation in China under global climate change and explored the directions of future litter accumulation research.
