摘  要:
利用156块人工林样地,建立了海南省松类、桉类、木麻黄、相思、橡胶等5个主要树种(组)的相对树高曲线模型。经检验,所有5个树种的模型,用于林分材积估计的总相对误差都在±1%以内,相对误差绝对值平均数小于3%,预估精度相当高。此外,还将5个树种合并进行了建模。将总模型分别树种进行材积估计检验,效果也相当理想,仍能满足建模精度要求。

摘  要:
The relative tree height curve models of main five tree species groups in Hainan Province, that is Pinus, Eucalyptus, Casurina, Acacia aug Hevea, are established by using 156 sample plots of plantation forests in this paper. All models of tive groups have high precision, the total relative errors for forest stand volume estimation are between ±1%, and the mean absolute reeors are lover than3%, in addition, a species-free model is established which work well for stand volume estimation of alltive tree species groups.
