This paper discussed the background of studies on tree form factor,the advantages and disadvantages of tree form factors existed,the significance and deficiency of New Absolute Formfactor,and possible way for further studies in this field.
论述了林木树干形数研究的历史背景、现有各种形数的优缺点、新绝对形数的意义、不足之处以及可能的发展方向。
Tree form factor growth regularity was studied using New Absolute Form factor(NAF) developde in 1997 by the authors,and a general trend was discovered that tree form factor increases as the tree age increases,and increases as the tree height increases.
利用创立的新绝对形数研究林木形质生长规律 ,发现林木形质生长的总趋势是随年龄增长而增长 ,且随树高的增大而增大 ;揭示了形数与高径比的关系 ;根据形数随年龄增长而增长的规律 ,提出了分别年龄组编制二元材积表的构想 ,并以华北落叶松为例编制了 ～ 龄级的二元材积
