692020III引言本标准根据LY/T 2103-2013根径立木材积表编制技术规程和湖北省一元立木材积表，结合宜昌市的树种根径及胸径调查数据编制，分别按照区域、起源和树种进行计算，共形成27个树种组（树种）的对应一元根径立木材积表，为森林资源调查提供了基础性工具。DB4205/T 6920201宜昌市一元立木根径材积测算技术规程1范围本标准规定了立木根径材积测算的术语和定义、单位及精度、适用区域及树种、根径测量方法、立木材积查找方法。本标准适用于宜昌市范围内松类（包括国外松、落叶松、马尾松、油松、华山松等）、杉类、硬阔、软阔、栎类、柏木及速生杨树（普通杨树归并为软阔类）等通过测量根径查找立木材积。2规范性引用文件下列文件对于本文件的应用是必不可少的。凡是注日期的引用文件，仅所注日期的版本适用于本文件。凡是不注日期的引用文件，其最新版本（包括所有的修改单）适用于本文件。LY/T 2103根径立木材积表编制技术规程3术语和定义3.1根径 tree root diameter树干距地面5cm处的直径。对于根部显著膨大的树种，根径为地面以上距地面不超过20cm处的直径，在数据采集时，可根据树种分别确定。3.2胸径 diameter at breast height又称干径，指乔木主干离地表面1.3m处的直径。对于1.3m以下分叉时，分株检尺；1.3m处树干异常的，在上下等距离（如10cm）分别检尺取平均值。3.3根径立木材积表 volume table based on the tree root diameter以根径为自变量、立木材积为因变量建立的对应关系。4宜昌市一元根径立木材积表编制方法4.1根径-胸径数学模型计算方法参照LY/T 2103执行。4.2根径-材积计算方法DB4205/T 6920202利用4.1计算出来的根径-胸径数学模型，结合湖北省一元立木材积表，得出根径-材积的数学模型。5单位及精度根径、胸径单位：cm，保留一位小数；立木材积单位：m3，保留四位小数。6适用区域及树种6.1适用区域1)宜西北自然区（鄂西北自然区）：远安县；2)宜东自然区（鄂东自然区）：枝江市、当阳市、宜都市；3)宜西南自然区（鄂西南自然区）：兴山县、长阳土家族自治县、五峰土家族自治县、秭归县、宜昌城区（含夷陵区）。6.2适用树种宜东杨树、宜东柏树（天然林）、宜东杉木（人工林）、宜东马尾松（天然林）、宜东马尾松（人工林）、宜东硬阔（天然林）、宜东硬阔（人工林）、宜东软阔（天然林）、宜东软阔（人工林）、宜西北柏木（天然林）、宜西北马尾松（人工林）、宜西北马尾松（天然林）、宜西北软阔（人工林）、宜西北软阔（天然林）、宜西北硬阔（人工林）、宜西北硬阔（天然林）、宜西南杨树、宜西南硬阔（天然林）、宜西南硬阔（人工林）、宜西南杉木（天然林）、宜西南杉木（人工林）、宜西南马尾松（天然林）、宜西南马尾松（人工林）、宜西南软阔（人工林）、宜西南软阔（天然林）、宜西南柏木（人工林）、宜西南柏木（天然林）。7根径测量方法检尺使用分度值为0.1cm的钢围尺，读数记到0.1cm。检尺时，应清除影响检尺的附着物，测量者在样木的上坡位，围尺应垂直、紧贴树干。8立木材积查找方法检尺之后，根据区域、树种、起源查找一元根径立木材积表（附录A）得出对应的材积。一元根径立木材积表按照纵向标题栏为根径整数位，横向标题栏为根径小数位，所对应的数值即为材积。例：在枝江市对已砍伐杨树树桩通过钢围尺检尺得到根径为10.3cm，按上述方法查询本规程附录A（宜东杨树一元根径立木材积表），纵向标题栏为10，横向标题栏为0.3，对应材积值为0.0255 m3，则该被砍伐杨树蓄积量为0.0255 m3。DB4205/T 6920203AA附录A（资料性附录）宜昌市一元根径立木材积表4DB4205/T
