北京山地不同林分乔木层生物量和生产力研究
Studies on Biomass and Productivity in the Different Forest Stands of Mountains in Beijing
摘要
Abstract
7 artificial pure forest stands were taken as the research object in the Beijing Mountain.The method of the relative growth was used to quantitatively study the tree layer (stem,branch,leaf,root and the whole plant) biomass and productivity,and analyze biomass regression relationship.The results show that:the trunks,branches and whole plant biomass and tree height,diameter at breast height was power function,and the relationship between biomass of roots and leaves,and tree height,DBH was described with two polynomial relation(R>0.81); different species biomass of each organ are different; the tree layer biomass varies form 29.56 to 35.09 t/hm2,order is Picea meyeri>Pinus tabulaeformis>Juglans mandshurica Maxim >Pinus armandii Franch.>Pinus bungeana Zucc.et Endi >Populus davidiana Dode>Platycladus orientalis (Linn.) Franco; net productivity is in the range of 2.06~9.44 t/(hm2 · a),order from big to small a mount is J uglans Mandshurica Maxim.> P inus tabuli f ormis > P icea me yeri > P inus bungeana Zucc.et Endi >Pinus Armandii Franch> Populus davidiana Dode> Platycladus orientalis (Linn.) Franco.Stand biomass mainly accumulates in roots and stems,productive accumulation mainly occurres in the trunks and branches in terms of material accumulation in each organ of tree.关键词
