摘要
用长白落叶松人工林３０２株解析本的数据，以全林分生长模型、林分结构分布模型、林分自然稀疏模型及因子相关模型为基础，配合削度方程和材积比方程，编制了林分材种出材率表，经检验精度符合要求，并实现了计算机选择材种、计算材积和出材率。
Stand outturn tables of wood sorts for Olga hay Larch(Larix olgensis)plantations were constructed based on stand growth models.models of distribution of stand structure, stand natural thinning models and factor correlation models and with equations of the taper. the ratio of volume and data of 302 stem analysis trees.By testing,the precision was satisfing. Wood buck could be done by computers.
