摘要/Abstract

摘要： 本文收集99株220年生红松的材积连年生长量材料,采用聚类分析方法,对我国天然红松林合理划分龄组问题进行了探讨。研究结果是:幼龄林1—80年,中龄林81—140年,近熟林141—160年,成熟林161—200年,过熟林201年以上。方差分析和多重比较的结果表明,相邻龄组间林木连年生长量差异显著,又与中华人民共和国林业部1982年颁发的《森林资源调查主要技术规定》中天然红松林龄组划分标准相比较,均证明本文划分标准比较科学合理。

Abstract: In accordance with the data of annual volume increments of 99 trees, 220 year-old Korean pine, the age groups of natural Korean pine forests are studied and analysed by the method of category assembling. The results are as follows: young forests, 1—80 years;middle age forests, 81—140 years; near mature forests, 141—160 years; mature forests, 161—200 years;over mature forests, over 201 years.Through variance analysis and multi-layered comparison, it shows that the differences of annual volume increments among the age groups are significant, and it is demonstrated that the abormentioned standard is scientific and reasonable. Perhaps this standard is better than that in the"some technical rules of investigating forest resources" issued by the Ministry of Forestry of China in 1982.
