摘    要:1 引 言林冠是森林生态系统中重要的组成部分。由于认识上、技术上和其它方面的原因 ,过去一直都把林冠当作“黑箱”来研究。近 2 0年来 ,随着对林冠生物多样性、林冠附生物在生态系统功能过程影响认识和研究技术上的提高 ,对林冠附生物的研究已逐步从个体水平转移到系统水平上。林冠现在被认为是一个适宜于许多动植物种类生存的场所 ,其物种数量比原先所想象的更为丰富。通过对林冠的研究 ,促进了对天然林生态系统中养分循环的了解 ,以及林冠干扰或破坏对自然和人类活动的影响。其中林冠附生物质在森林生态系统养分循环过程中的作用和影…

关 键 词:森林生态系统  物质循环  林冠附生物

Abstract:As a component of many forest ecosystems, Epiphytic material (EM) plays important ecological roles in nutrient cycling and conservation. The ecological research on EM in forest, which has become important content of forest canopies study and the basis for significant reappraisal of ecosystem function in temperate and tropical forest environments, have received much attention of scientists of ecology, biology, hydrology, etc. recently. This paper gives definition of EM, introduces background and contents of EM study, summarizes the advances on ecological researches of EM, and looks into the prospect for developing trend of EM study in the future. The paper points out that EM and its effects on nutrient cycling should be paid much attention in the study of structure and function of forest ecosystems in China in order to better understand the dynamics of forest ecosystem and make rational use and protection of forest resources.
Keywords:Epiphytic material  nutrient cycling  forest ecosystem
