林冠是树木光合作用的主要层次,林冠结构造成的林下光环境差异对于植物的生长和群落的更新演替有着重要的生态学意义。冠层结构的重要作用已引起全球生态学家的高度重视,国际科学界已举行了三届国际冠层大会,认为合作并发展全球冠层研究计划是必须的。文章较系统地介绍了国内外冠层结构、林内环境、林下植被组成及土壤环境之间的一系列相互关系的研究进展,并将近年来有关森林冠层结构最新研究方法作简单介绍,为今后的同类研究提供参考。
Light conditions are very important determinant of forest understory vegetation pattern.Forest canopy structure is the main photosynthetic layer and determined light status of the understory.It is a consensus in forest ecology that understory light plays a prominent role in the growth of the plant and affected the succession of the forest community.International scientists considered it is necessary to develop and co-operate the plan of the canopy study in the world.The importance of the canopy study has at...
