主要树种的生产力

1、4.华北地区主要森林类型生物量和生产力研究4.1 华北落叶松生物量和生产力研究4.1.1 华北落叶松生物量研究本文运用生物量模型的方法来估计落叶松林生物量，误差较小。常用的森林生物量模型估算方法主要是利用树木(包括树干、树枝、树叶和树根)实测的生物量与树木胸径(D)或胸径平方与树高的乘积(D2H)建立相对生长方程来进行估算的。本文在韩有志、李玉娥等在华北落叶松人工林林木生物量的研究成果及谭绪泉等人研究华北落叶松自然稀疏模型基础上，结合标准地调查，解析木分析计算获得了承德地区落叶松林各部分生物量，计算结果如下表：图4-1 华北落叶松各部分生物量比例表4-1 承德地区落叶松单株各部分生物量表 (
