摘要 选择伏牛山国家级自然保护区的五种典型植被类型作为研究对象,对15块临时样方内的乔木树种,分别测量出树高,胸径等因子,通过异速生长模型进行不同乔木树种生物量测定,进一步进行分析.结果表明,在选取的五种典型森林植被中,生物量大小依次为落叶针叶林>落叶阔叶林>针阔混交林>常绿针叶林>锐齿槲栎林.在落叶针叶林中,日本落叶松各个器官生物量在总的生物量所占比重从大到小依次为树干>树根>树枝>树皮>树叶.这一生物量分配格局既有利于日本落叶松的自身生长,也体现了对环境的适应性.在落叶针叶林、落叶阔叶林、针阔混交林、常绿针叶林、锐齿槲栎林中,乔木树种的地上生物量均大于地下生物量,尤其是对于落叶针叶林来说,地上生物量远远大于地下生物量. In this paper we chose five kinds of typical vegetation type as the research objects in the nature reserveof Funiu mountain within the 15 pieces of temporary samples on tree species,respectively,then measured the treeheight,diameter at breast height,and other factors. Through determination of different tree species biomassallometric growth model,we analyzed the biomass and further results. The selection of five kinds of typical forestvegetations,show the biomass sizes as deciduous coniferous forest〉deciduous broad-leaved forest〉mixed forest〉evergreen coniferous forest〉needle sharp tooth oriental white oak forest. In deciduous coniferous forest,Japaneselarch various organ biomass in total biomass accounted for the order from large to small is the trunk〉root〉branch〉bark〉leaf. The biomass allocation pattern is conducive to the growth of Japanese larch,also reflected the adaptability tothe environment. In deciduous coniferous forest,deciduous broad-leaved forest,mixed forest,evergreen coniferousforest,needle sharp teeth,oriental white oak forest,the ground biomass of tree species are greater than theunderground biomass,especially for deciduous coniferous forest,the biomass is far greater than the undergroundbiomass on the ground.
