树高是计算材积三要素之一,林分平均树高的高低直接影响林分蓄积量的大小。然而,现实林分的平均树高与原始林分平均树高(未经破坏)不一样,原始林分平均树高比现实林分平均树高要高。各径级树高的差异也较明显,笔者收集了丽江县云南松未经破坏的原始 Tree height is one of the three elements of calculating volume, the average height of the tree stand directly affects the size of the stock volume. However, the average tree height of the actual stands is not the same as that of the original stands (unspoiled), and the average height of the original stands is higher than that of the actual stands. The difference between the different diameter tree-level is also more obvious, I collected Lijiang County, Yunnan pine untouched primitive
