    Construction of tree volume equations for Chinese fir plantation in Guizhou Province, southwestern China.

    • 摘要: 森林蓄积是森林生物量的主要组成部分,是各类森林资源监测的重要指标,森林蓄积的计量标准是立木材积表或材积方程。本文利用贵州省1 840株人工杉木的立木材积实测数据,通过采用度量误差模型方法,研究建立了中心区和一般区的相容性一元和二元立木材积方程及树高曲线方程。结果表明:中心区和一般区的一元立木材积方程和树高曲线方程有显著差异,而二元立木材积方程则相差很小。在此基础上建立了全省通用的二元立木材积方程。

       

      Abstract: Forest volume, being the major component of forest biomass, is an important item in forest resource monitoring, which is estimated from tree volume tables or equations. Based on tree volume data of 1 840 sample trees from Chinese fir (Cunninghamia lanceolata) plantations in Guizhou Province of southwestern China, the compatible one and twovariable tree volume equations and tree height curve equations for central and other regions were constructed using errorinvariable modeling method. The results showed that onevariable tree volume equations and height curve equations between central region and other region were significantly different, neither the twovariable volume equations were. Based on this, the provincial generalized twovariable tree volume equation was established.
