摘　　要：为掌握木材在"采伐—运输—销售"过程中的变化,以广西斯道拉恩索林业有限公司(SEGX)的一个作业小班为例,将采伐机自动记录的去皮数据作为原始参考值,测算小班原木分楞堆、卡车和销售3个阶段的材积,并分析材积的变化,其结果显示:除楞堆到卡车运输的材积变化较大外,其他过程的差异均在许可范围(±10%)内。Log output volume was a reflection of commercial forest value,which would directly affect the economic profits of forest management units,so it played an important role in capitalized management of forest recourses.In order to master output changes during the process of harvesting-transportation-sale,this paper took an operational sub-compartment of Guangxi Stora Enso Forestry Co.,Ltd（SEGX） as a sample,and considered the harvester under-bark data as original reference value.Log volume was measured and calculated for three times which were pile measurement,truck measurement and sale.Changes of volume among each stage were also analyzed.Results showed that the error between pile measurement and truck transportation was bigger（13.9%）,other errors were reasonable（±10%） except this one.

关 键 词：原木出材量 楞堆测量 卡车测量 材积变化
