摘　　要：编制马尾松二元立木材积表,为准确测量广西马尾松森林蓄积量提供理论依据。在广西马尾松Ⅰ类、Ⅱ类和Ⅲ类产区采集712株样木,选取4个常用模型分别构建马尾松二元材积模型,综合总相对误差(TRE)、平均百分标准误差(MPSE)、平均系统误差(ASE)、预估精度(P)以及参数变动系数等指标进行对比选优,确定山本式固定参数模型V=0.000 076 45×D1.758 591 82×H1.008 345 76为马尾松二元材积模型。对该模型进行整体、分产区、分胸径和树高段及独立样本检验,结果表明该模型的拟合质量高,预估效果良好,达到编制二元材积模型的精度要求,可广泛适用于广西马尾松森林资源调查、林业司法鉴定和伐区作业调查设计等工作。The construction of a binary standing tree volume table for Pinus massoniana provides a theoretical basis for accurately measuring forest stock volume in Guangxi.This study collected data from 712 sample trees across three production areas(Class I,II,and III)of P.massoniana in Guangxi.Four commonly used models were selected to construct binary volume models for P.massoniana.Through a comprehensive comparison of total relative error(TRE),mean percent standard error(MPSE),average systematic error(ASE),forecast accuracy(P),and parameter variation coefficients,the Yamamoto fixed-parameter model,V=0.00007645×D1.75859182×H1.00834576,was determined to be the optimal binary volume model.The model was then subjected to validation by production areas,diameter,height segments,and independent sample testing.Results showed that this model demonstrated high fitting quality and excellent predictive performance,meeting the accuracy requirements for constructing binary volume models.It can be widely applied in forest resource surveys,forestry judicial appraisal,and operation surveys and designs for P.massoniana forests in Guangxi.
