摘  要:
应用吉林省汪清林业局金沟岭林场收集的83株过伐林云杉解析木资料,研究年龄与树高、胸径、材积之间的相关关系,经过拟和,结果表明云杉树高——年龄的生长方程为二次抛物线方程,胸径——年龄、材积——年龄的生长方程为S型曲线方程,相关指数达到97%以上,为预测金沟岭地区云杉树高、胸径、蓄积的生长及经营提供了依据。

摘  要:
Based on the data on 83 Picea koraiensis Nakai trees in the over-logged area of Jingouling forest farm of Wangqing County Jilin Province,the relevance between age and tree height,DBH,volume were studied.The result indicated that the growth equation of the optimum relations of height-age was Parabolic equation,and the growth equation of the optimum relations of diameter-age and volume-age both were S curve equation.Their related coefficient was above 95%.The research will offer basis for predicting the growth high,DHB and volume of Picea koraiensis Nakai in this area.
