摘要
林冠层作为森林生态系统的组成部分之一,截获光能、降雨,决定林分郁闭程度,从而影响林分生产力及空间利用程度,是树木重要的生理生态活动场所,因此对低质低效林林冠层格局的改变是林相改造的重要手段。本文对陆地乔木树冠结构中枝条属性因子、树冠轮廓形状、树冠大小、叶片、树冠生物量5个方面进行研究综述。研究树体结构,尤其是树冠的空间结构对实现森林质量精准提升、加快生态修复、人工林产业化发展有着重要意义。
Crown layer is one of the component structures of forest ecosystems.It can intercept sunlight,rainfall and decide canopy density,thus it affects forest productivity and spatial utilisation rate.It is a place of important physiological and ecological activity for trees.For low-quality forest stands,changes to the forest canopy structure can be one way to effect forest form improvement.In order to guide research on crown structure,the authors summarized reported research results under five aspects of tree canopy structure:branch attributes;crown profiles;crown size;leaf biomass;and,canopy biomass.The study of tree structure,especially the spatial structure of the canopy,is of relevance to improving forest quality,accelerating ecological restoration and developing industrialization of plantation forests.
