Research Abstract

Allometric relationships are the powerful tool for estimating forest biomasses. However, these relationships often show the segregation among forest types and tree species. For establishing them in fields, laborious works are necessary, and so common equations based on some biological laws are awaited for applying them to various types of forest stands. In this study, the pipe model and static model of plant forms are used for establishing allometric relationships on the above-ground weight and root weight of trees, based on the individual tree weights of cool-temperate and warm-temperate forests. The relative errors of determined common equations were 13.84% and 19.00% respectively for above-ground and root weights. These relative errors were less than those of ordinary allometric relationships used for estimations. These common equations will become a powerful tool for estimating biomasses in temperate forests.
