摘要: 基于广西第七次、第八次森林资源清查数据中马尾松样地样木资料,对不同起源下的单木和林分材积生长率模型进行对比分析。结果表明:对数函数模型Y=a+bln(X)和幂函数模型Y=a×Xb,分别作为单木和林分不同起源下的最优材积生长率模型。马尾松幼龄林生长期,人工林材积生长率要高于天然林,且变化幅度大;生长后期,天然林材积生长率要高于人工林,变化趋向平稳。单木不同起源间的材积生长率差异显著,林分不同起源间差异不显著。

Abstract: Based on Pinus massoniana plot data of sixth and seventh continuous forest inventories in Guangxi Province,the analysis results of individual tree and stand volume growth rate model under different origins are as follows:logarithmic function model Y=a+bln(X) and power function model Y=a×Xb respectively as individual tree and stand under different origins of optimal volume growth rate model .In the growth period of young pinus massoniana forest,volume growth rate of the artificial forest is greater than the natural forest and has large varied amplitude,at the later growth stage,volume growth rate of the natural forest is greater than the artificial forest and has stationary varied amplitude.The difference of volume growth rate between different origins of individual tree is significant,the difference between different origins of stand is not obvious.

Key words: Pinus massoniana, volume growth rate, model
