地径-胸径对照表硬阔

1范围

本文件规定了抚顺市《地径-胸径对照表硬阔》的规范性引用文件、术语和定义、确定模型、地径

-胸径对照表建立和使用。

本文件适用于硬阔的单株地径-胸径对照测算。

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。

3术语和定义

下列术语和定义适用于本文件。

3.1

硬阔

黑桦、色树、榆树、花曲柳、水曲柳、胡桃楸、怀槐、黄波罗等。

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）5cm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。

4确定模型

地径-胸径模型

22

D1.3=1.857215+0.112094D0ln(D0)-0.003554D0…………(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-胸径对照表硬阔。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6cm-94cm。本文件可

参照确定模型适当推算至地径200cm。

本文件的最终解释权归编制单位。
