| 摘 要： | 以吉林省敦化市落叶松和红松人工林为研究对象,随机抽取342株落叶松（Larix spp.）和298株红松（Pinus koraiensis Sieb.et Zucc.）为编表样木,利用非线性麦夸特迭代求解法选出最优一元材积模型。以202株落叶松和170株红松为验表样本,适用性检验结果表明,材积表估计的系统误差均小于3%,满足林业生产材积估计的精度要求。因此本文所编敦化市落叶松和红松人工林材积表适用于敦化地区,可应用于生产实践。

| Abstract: | This article takes artificial larch plantations and Korean pines in Dunhua City as the research object,randomly selects 342 larches（Larix spp.） and 298 Korean pines（Pinus koraiensis Sieb.et Zucc.） as samples and uses nonlinear Marquardt computation to select optimal unitary volume model.Based on the samples of 202 larches and 170 Korean pines,the result of applicability test shows that the systematic errors of volume table estimation are less than 3%,which meets the precision requirement of forestry production.Therefore,the volume table established in this paper is suitable for Dunhua area and can be used in production. |
