森林冠层结构与功能及其时空变化研究进展

The Research Advances on the Structure and Function of Forest Canopy,as well as Their Temporal and Spatial Changes

林冠是森林与外界环境相互作用最直接和最活跃的界面层 ,同时 ,它本身又承载了森林生物多样性的主体部分。森林冠层研究的方法和技术在近些年取得了长足发展 ,从而促进了有关林冠结构与功能的研究。这些研究深化了人们对于林冠结构与光能截获以及群落干物质积累之间关系的认识 ,同时 ,对于森林冠层的物质循环和能量传输以及冠层内各营养级之间相互关系动态也有了更为深入的理解。考察森林冠层的结构与功能及其时空变化是深入理解整个森林生态系统的格局、过程及其运作机制的重要基础。

Forest canopy is regarded as a most direct and active interface between the forest and its outer environment. At the meantime, it also contains the main part of the forest biodiversity. The methods and techniques for studying forest canopy have progressed greatly in the recent years, which promoted the researches on the forest canopy structure and function. These researches deepened the recognition on the relationships between the forest canopy, light capture and dry matter accumulation within the community, and also, deepened the understanding of the material cycle, energy flow and the dynamics of interrelations among the trophic levels within the canopy. The studies on the forest canopy structure and function as well as their temporal spatial changes are the bases for deep understanding the pattern, process and mechanism of whole forest ecosystem.
