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 1 6.77t/ 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 。
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/hm 2,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.
