摘要
以北京地区栓皮栎人工林为研究对象,应用典型样地调查法和相对生长法对乔木生物量展开研究,结果显示:各器官中生物量大小顺序为树干>枝条>叶片,其中树干约占65%,树冠约占35%。通过回归分析探讨了各变量的相关性,并对其各器官的生物量与胸径和树高进行模型拟合。其中树干和树冠的生物量与胸径、树高的拟合方程分别是:W=0.018(D2H)1.09、W=0.9(D)2.128。
The typical plot survey method and relative growth method were used for the research of plantations of the biomass of Quercus variabilis Blume in beijing regions were studied in order to reveal the biomass allocation.The results showed that the size order of every organ's biomass in arbor layer was trunksbranchesleaves.Some 65 percent were trunks and 35 percent the crown.The correlations among various organs were probed by regression analysis.The biomass fitting models of various organs were W=0.018(D2H)1.09、W=0.9(D)2.128 respectively.
