林业数表编制数据采集技术规程3术语和定义下列术语和定义适用于本文件。3.1柞树柞树（Quercus L.）属于壳斗科栎属植物，落叶乔木，分布于抚顺市的主要种有：辽东栎（Quercusliaotungensis）、蒙古栎（Querus mongolica）、檞栎（Quercus aliena）等。3.2胸径树干直径分为带皮直径和去皮直径两种，测量单位是厘米（cm）。树干直径随其在树干上的位置不同而变化，从根颈至树梢树干直径呈现出由大到小的变化规律。其中位于距根颈1.3m处的直径，称为胸高直径，简称为胸径。3.3地径指林木距地面（坡面时上坡口）0cm处伐根围尺直径。3.4建模单元具有地域的连接性和行政区的完整性以及自然条件的一致性的区域组合。DB2104/T 0025-202324确定模型地径-胸径模型D1.3=2.740324+0.356272ln(D1.50)-0.002111D20(1)式中：D0地径；D1.3胸径。5地径-胸径对照表建立和使用5.1地径-胸径对照表建立以非线性模型为基础，根据编表样本地径变化范围，按胸径表格式建立地径-胸径对照表柞树。详见附录A。5.2使用范围地径-胸径对照表应在编表区域内满足编表单元条件的林木中使用，地径径阶8cm-96cm。本文件可参照确定模型适当推算至地径300cm。本文件的最终解释权归编制单位。DB2104/T
