摘 要:广义干曲线方程是研究林分生产力状况的有效方法.利用所建立的杉木人工林广义干曲线模型模拟不同立地、不同密度、不同年龄杉木人工林单株材积和林分蓄积量,并与杉木二元材积公式(《立木材积表》(Ly208-77))计算的相应单株材积和林分蓄积量进行对照,比较结果高度一致.说明运用该广义干曲线模型模拟不同集约经营条件下的杉木人工林具可行性,在生产实践中有可应用性.The generalized stem form model proved to be a useful method in stand productivity studies. Based on the established generalized stem form model (GSFM) for Chinese fir plantation, the single-tree volume and stand volume of plantations, in different site conditions and with different densities and ages, were calculated. The result (V) was compared with that (V0) obtained from binomial volume function for Chinese fir, approved by the tree volume table (Ly208-77), and the difference between V and V0 was extremely small. This indicates that the GSFM could be applied in practice to analyzing the single-tree or stand volume for Chinese fir plantation under different intensive cultivation conditions.
