標準解讀

《GB 4814-1984 原木材積表》是中國關于原木體積計算的標準規(guī)范，發(fā)布于1984年。此標準主要用于統(tǒng)一和規(guī)范原木體積的測量方法與計算規(guī)則，確保在林業(yè)生產(chǎn)、貿(mào)易及科研活動中，原木體積的測定有統(tǒng)一的標準可循，以提高數(shù)據(jù)的準確性和可比性。以下是該標準的主要內(nèi)容概覽：

  1. 適用范圍：本標準規(guī)定了不同樹種、直徑區(qū)間原木的材積計算方法。適用于未經(jīng)去皮或已去皮的原木體積估算，不包括鋸材和其他木制品。

  2. 原木分類：根據(jù)原木的直徑大小，標準將原木分為若干直徑區(qū)間，每個區(qū)間對應不同的體積計算公式或圖表，以適應不同尺寸原木體積變化的特點。

  3. 材積計算方法：標準提供了基于原木直徑和長度的體積計算公式。通常，計算過程涉及測量原木的小頭直徑（即原木兩端中較小一端的直徑）、大頭直徑（較大一端直徑）以及原木的實際長度，然后依據(jù)這些尺寸在材積表中查找到對應的體積值或通過公式直接計算。

  4. 材積表使用：標準附帶的原木材積表是按樹種和直徑區(qū)間編制的，用戶需先確定原木的樹種和直徑范圍，再根據(jù)實際直徑和長度查找或計算出相應的體積。材積表可能包括一系列預計算的體積值或插值方法，以便于快速準確地獲取體積數(shù)據(jù)。

  5. 修正系數(shù)：在某些情況下，如原木形狀不規(guī)則、有明顯彎曲或瑕疵時，標準可能提供修正系數(shù)或指導原則，用以調(diào)整初始計算得到的體積，以更接近實際可利用的木材量。

  6. 精度要求：標準對測量工具的精度、測量方法的規(guī)范性以及最終計算結果的精確度提出了具體要求，確保所有操作符合一定的技術標準，減少誤差。

  7. 實施與監(jiān)督：標準的實施旨在促進原木交易的公平合理，提升行業(yè)管理效率。相關部門負責監(jiān)督標準的執(zhí)行情況，確保其在實際應用中的準確性和一致性。

本標準適用于所有樹種的原木材積計算。

1檢尺徑自4～12cm的小徑原木材積由公式

V＝0.7854L（D＋0.45L＋0.2）2÷10,000

確定。

2檢尺徑自14cm以上的原木材積由公式

V＝0.7854L〔D＋0.5L＋0.005L2＋0.000125L（14－L）2·（D－10）〕2÷10,000

確定。

3原木的檢尺長、檢尺徑按GB144.2—84《原木檢驗尺寸檢量》的規(guī)定檢量。

4檢尺徑4～6cm的原木材積數(shù)字保留四位小數(shù)，檢尺徑自8cm以上的原木材積數(shù)字，保留三位小數(shù)。
