地徑-胸徑對照表軟闊

1范圍

本文件規(guī)定了撫順市《地徑-胸徑對照表軟闊》的規(guī)范性引用文件、術(shù)語和定義、確定模型、地徑

-胸徑對照表建立和使用。

本文件適用于軟闊的單株地徑-胸徑對照測算。

2規(guī)范性引用文件

下列文件對于本文件的應(yīng)用是必不可少的。凡是注日期的引用文件，僅所注日期的版本適用于本文

件。凡是不注日期的引用文件，其最新版本（包括所有的修改單）適用于本文件。

3術(shù)語和定義

下列術(shù)語和定義適用于本文件。

3.1

軟闊

凡是木材端面硬度達(dá)到701公斤/平方厘米及其以下的，即稱軟闊葉樹種。

包括白樺、山楊、柳、椴樹等。

3.2

胸徑

樹干直徑分為帶皮直徑和去皮直徑兩種，測量單位是厘米（cm）。樹干直徑隨其在樹干上的位

置不同而變化，從根頸至樹梢樹干直徑呈現(xiàn)出由大到小的變化規(guī)律。其中位于距根頸1.3m處的直徑，稱

為胸高直徑，簡稱為胸徑。

3.3

地徑

指林木距地面（坡面時上坡口）0cm處伐根圍尺直徑。

3.4

建模單元

具有地域的連接性和行政區(qū)的完整性以及自然條件的一致性的區(qū)域組合。

4確定模型

地徑-胸徑模型

1.2

D1.3=-5.662372+0.246904D0+3.831239ln(D0)………………(1)

式中：

D0—地徑；D1.3—胸徑。

5地徑-胸徑對照表建立和使用

5.1地徑-胸徑對照表建立

以非線性模型為基礎(chǔ)，根據(jù)編表樣本地徑變化范圍，按胸徑表格式建立地徑-胸徑對照表軟闊。詳

見附錄A。

5.2使用范圍

地徑-胸徑對照表應(yīng)在編表區(qū)域內(nèi)滿足編表單元條件的林木中使用，地徑徑階6cm-82cm。本文件可

參照確定模型適當(dāng)推算至地徑200cm。

本文件的最終解釋權(quán)歸編制單位。
