树冠是树木进行一系列生理活动的主要场所,采用全树收获法,对不同密度的枝叶生物量在冠内的垂直分布规律进行分析。结果表明,冠层位置对枝叶生物量分布影响显著,冠层枝生物量与叶生物量均随冠层深度的增加呈先增加后减少的变化趋势。 Canopy is the main site for trees to conduct a series of physiological activities. The whole tree harvesting method was used to analyze the vertical distribution of the biomass of branches and leaves in different densities in the crown. The results showed that the position of canopy significantly affected the biomass distribution of branches and leaves. The biomass of crown branches and leaf biomass increased first and then decreased with the increase of canopy depth.
