摘要: 以Weibull方程为基础模型，使用1 680株标准木数据，分别为长白山主要的7个树种建立了树高曲线方程。研究发现，针叶树种的树高曲线具有较高的精度，决定系数R2均在0.8以上，而阔叶树的精度较低，尤其椴树Tilia amurensis和榆树Ulmus pumila的R2低于0.5。对比针阔叶树的树高曲线发现，在胸径较小时，阔叶树的树高普遍较高，而在胸径较大时，针叶树的树高较大。从相邻径阶的树高之差来看，针叶树的径阶树高生长量普遍较大。由于相同径阶的林木，径阶树高生长量越大，其材积生长量越大。因此，在林分调整采伐时，应尽量保留径阶树高生长量较大的林木。单纯从木材收获的角度出发，在长白山地区，相同径阶下主要针叶树种的采伐顺序应为臭冷杉Abies nephrolepis，红松Pinus koraiensis和红皮云杉Picea koraiensis。图2表2参8

Abstract: The study of height-diameter model is a basic research in forest growth and yield modeling. It might imply some information for regulation stands by comparing height-diameter models of different tree species in the same forest. The Weibull function was chosen to develop height-diameter models by using 1 680 sample trees of seven main species on Changbai Mountains，including three coniferous species：Picea koraiensis，Abies nephrolepis，and Pinus koraiensis，and four broadleaf species：Betula costata，Tilia amurensis，Acer mono，and Ulmus pumila. The decision coefficient R2 of height-diameter models for coniferous species were above 0.821 and for broadleaf species were between 0.474 － 0.746. When tree diameter was small，the height of broadleaf species was higher than coniferous species，whereas when diameter was large，height for coniferous species was higher. Also，the height increment between adjacent diameter classes was generally greater in coniferous species. Because volume will be greater for taller trees with the same diameter，when regulating the stands，trees with larger height increments should be maintained. Therefore，on Changbai Mountains if only timber production is considered，cutting the main coniferous species having the same diameter should be in the order：Abies nephrolepis，Pinus koraiensis，and Picea koraiensis.［Ch，2 fig. 2 tab. 8 ref.］
