| 摘 要： | 为估算长白落叶松的去皮直径及树皮厚度等,利用小兴安岭南部68株长白落叶松解析木与生物量数据,对带皮胸径与去皮胸径之间、树干材积与木材材积之间、树皮厚度与相对树高之间、树皮因子与树高之间等相关模型进行了研究.结果表明,长白落叶松胸径处去皮直径的最优模型为D1B=0.922DOB(R2=0.99),胸径处树皮因子和树皮调整...

| Abstract: | Models expressing relationships between outside and inside bark diameter at breast height(DOB and DIB),stem volume and wood volume,bark thickness and relative tree height as well as bark factor and tree height were studied using data of analytic wood and biomass of 68 sample trees of Larix olgensis in southern Xiaoxing'an Mountains,Northeast China,in order to estimate the diameter under bark and bark thickness.Results showed that the best fitting model for inside bark diameter at breast height was DIB=0.922... |
