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,分别拟合椴树最优树高-年龄、胸径-年龄、材积-年龄的生长方程,经检验达到精度要求,为预测该地区椴树树高、胸径、蓄积的生长提供理论依据。
Analysing the data on 38 anatomized Tilia amurensis trees in the over-logged area of Jingouling forest farm of Wangqing County,Jilin Province, the relevances between age and tree height, DBH,volume are studied. Its optimal growth equations of height-age, diameter-age and volumeage are imitated,which can come to the required precision. The research will offer theoretical basis for predicting the growth of high, DHB and volume. of Tila amurensis there.
