摘要
杉木人工林为安福县重要的森林资源,本研究根据1 526株样木数据,在分析其干形变化特点的基础上,建立了符合安福县实际的杉木人工林二元立木材积动态模型。经适用性检验,该模型精度高,其参数稳定可靠,能对样木客观规律作出解释。模型适合在安福县使用。
Cunninghamia lanceolata plantation has become an important forest resource in Anfu County. This paper is based on the data of 1 526 sample trees. On the basis of analyzing the characteristics of the tree trunk changes, the two-way tree volume model which being validated for the C. lanceolata plantation in Anfu County was established. After testing the applicability, the model has high accuracy, stable and reliable. The parameters of the model can explain the objective law of wood reflected. The model is recommended for use in Anfu County.
