# 制材出材率计算器

出材率与原木规则超产率——对照 FAO 与欧盟数据。

输入进厂圆木材积和出厂锯材材积，得到出材率，并与 FAO、欧盟及东南亚参考区间对照。也可补填原木规则板尺和实际锯得板尺，计算 Doyle/Scribner 的超产或欠产。

## FAQ

出材率多少算好？

取决于地区和原木质量：欧盟硬木厂平均约 38%，软木厂 48%，FAO 全球调查为 42–60%、均值 50.8%。东南亚热带人工林场用带锯约 52%，链锯只有约 39%。

什么是原木规则超产率？

原木规则估算一根原木应出多少板尺。超产率是实际产量超出规则估算的百分比：(实际 − 规则) ÷ 规则 × 100。Doyle 规则低估小径木，按 Doyle 收购的厂常见 10–30% 超产；大径木则可能欠产。International 1/4″ 是最准确的规则。

小型制材厂怎么提高出材率？

带锯的锯缝损耗小于链锯和圆锯（东南亚数据为 52% 对 39%）；用锋利的薄锯缝锯条、仔细的原木定位与裁边、按短规格出售都有帮助。第一步是按原木批次记录出材率并与上述基准对照。
