浙江天童苦槠+白栎灌丛群落的生物量研究

Studies on the Biomass of ,i>Castanopsis sclerophylla+ Quercus fabri Shrubland in Tiantong Region,Zhejiang Province

摘要: 采用直接收获法研究了浙江天童地区苦槠+白栎次生灌丛群落的地上部分生物量。结果表明该区次生灌丛的地上部分生物量为16.77t/hm₂,还不到常绿阔叶林幼林生物量(地上部分)的1/3。次生灌丛生物量的分布,从群落层次上看,主要集中于灌木层;从垂直高度上看,主要分布在0～4m之间;从种类组成上看,主要分布于苦槠、白栎、山矾、茅栗等优势种中。根据生物量的研究,文中还对如何加速次生灌丛的进展演替进行了讨论。

Abstract: The harvest method is used to study plant aboveground biomass of Castanopsis sclerophylla + Quercus fabri shrubland in Tiantong region,Zhejiang Province.The result shows that the aboveground biomass of the shrubland is 16.77 t/hm²,less than 1/3 of that of evergreen broad leaved young forest.From the community layer,vertical height,and species composition point of view,the biomass mainly distributes in shrub layer,0～4 meter and dominant species such as Castanopsis sclerophylla,Quercus fabri,Symplocos sumuntia,Castanea seguinii respectively.Based on the biomass of the shrubland,the question on how to accelerate its progress succession is also discussed.
