摘要
本研究根据吉安地区不同立地条件的大量解析木资料,在分析其干形变化特点的基础上,首次提出了湿地松二元立木动态材积模型。材积模型经适用性检验表明:具有精度高、稳定可靠的特点。该模型不但能充分利用样木信息,而且参数能对样木信息资料所反映的客观规律作出解释。材积模型可以在研究区域范围内推广使用。
Slash plive plantation becomes one of the most important forest resources in Jiangxi provinceAccording to the stem analysis data under different soil condition in Jian region, and based on the analysis of the variation traits of the stem form, a binary standing volume model of slash pine is provided for the first time. The results of goodness-of-fit test show that the volume model has the characteristics of high precision, stability and reliability for application. The model can not only use the sample information fully but also explain the objective rules reflected by the information. It can be applied within the research area.
