By the method of clear cutting, a measurement was made on the aboveground biomass (AGB) of 24-year old natural Castanopsis carlesii-Schima superba community in an 800 m2 plot in Xiaokeng of Nanling Mountains, South China. The distribution patterns of the total AGB in different forest layers, tree species, and tree layer organs were investigated, and the AGB regression models were constructed. The results showed that when constructing the AGB regression models, more than 12 samples would be feasible. Based on the measured AGB of 265 felled trees, the AGB models of mixed broadleaved species were AGB = 0. 128D(2.372) and AGB = 242.331(D2H)(0.947). The single tree's AGB model of C. carlesii, S. superba, and Cunninghamia lanceolata was also established. The total AGB of the forest community was 115.20 t x hm(-2), of which, the AGB of tree layer, understory layer, liana, and litter layer was 111.25, 1.01, 0.36, and 2.58 t x hm(-2), respectively. The AGB of C. carlesii and S. superba took up 39.1% and 28.7% of the tree layer AGB, respectively. The AGB of tree stem and branch-leaf occupied 81.0% and 19.0% of the tree layer AGB, respectively.
采用皆伐法，对中国南方南岭小坑一块800平方米样地中24年生天然米槠-木荷群落的地上生物量（AGB）进行了测定。研究了不同林层、树种和乔木层器官中总AGB的分布格局，并构建了AGB回归模型。结果表明，构建AGB回归模型时，12个以上的样本是可行的。基于265株伐倒木实测的AGB，混交阔叶树种的AGB模型为AGB = 0.128D(2.372)和AGB = 242.331(D2H)(0.947)。还建立了米槠、木荷和杉木单株的AGB模型。森林群落的总AGB为115.20 t·hm(-2)，其中乔木层、林下植被层、藤本植物层和凋落物层的AGB分别为111.25、1.01、0.36和2.58 t·hm(-2)。米槠和木荷的AGB分别占乔木层AGB的39.1%和28.7%。乔木树干和枝叶的AGB分别占乔木层AGB的81.0%和19.0%。
