摘要
利用吉林省汪清县金沟岭林场收集的38株过伐林椴树解析木资料,研究椴树年龄与树高、胸径、材积之间的相关关系,结果表明椴树最优树高-年龄、胸径-年龄、材积-年龄的生长方程为:H=0.329e-0.133 1A;D=-0.001 1A2-0.001 8A+0.243 2;V=-7E-05A2+0.000 8A-0.000 8,经检验精度为92.3%。
The paper studies the relevance between the age and tree height, diameter at breast - height as well as volume of timber through the data of 38 anatomized Tilia amurensis trees of over - logged area in Jingouling Forestry Farm, Wangqing county of Jinlin Province. The result indicates that the growth equation of the opti- mum relations of height-age, diameter - age and volume - age as following： H = 0.329e^-0.1331A; D = - 0.001 1A^2 - 0.001 8A ＋ 0.243 2; V = - 7E - 05A^2 ＋ 0.000 8A - 0.000 8. Through testing, the precision shows 92.3 % as a result.
