摘要: 以杉木和马尾松604株样木的地上生物量和212株样木的地下生物量实测数据为基础,利用非线性混合模型和哑变量模型方法,建立了包含林分起源的立木地上生物量和地下生物量模型,分析了林分起源对模型参数的影响。结果表明:不同起源的立木地上生物量模型没有明显差异,而地下生物量模型则存在显著差异,相同直径和树高天然林木的地下生物量明显高于人工林木;杉木天然林木的地下生物量比人工林木大近30%,而马尾松天然林木的地下生物量比人工林木要大约45%。

Abstract: Based on the measurement data of aboveground biomass from 604 sample trees and underground biomass from 212 sample trees of Chinese fir(Cunninghamia lanceolata)and Masson pine(Pinus massoniana)in southern China,the single tree above and under ground biomass models involving forest origin were constructed by using nonlinear mixed model and dummy variable model approaches,and the impact of forest origin on biomass models was analyzed.The results showed that the aboveground biomass models for different origins had no significant difference,while the underground biomass models were significantly different,from which the underground biomass estimate of natural tree with same diameter and height was highly greater than that of planted tree.Specially,the underground biomass estimates of natural trees are nearly 30% and about 45% greater than those of planted trees for Chinese fir and Masson pine respectively.

Key words: aboveground biomass, underground biomass, forest origin, mixed model, Chinese fir, Masson pine
