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.］
