引  言

本标准根据LY/T2103-2013《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。

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。

LY/T2103根径立木材积表编制技术规程

3术语和定义

3.1

根径treerootdiameter

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diameteratbreastheight

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volumetablebasedonthetreerootdiameter

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/T2103执行。

4.2根径-材积计算方法

1

DB4205/T69—2020

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0.0255m3，则

该被砍伐杨树蓄积量为0.0255m3。
