Additive allometric models of single-tree biomass of two-needled pines as a basis of regional mensuration standards for Eurasia

Abstract

When using the unique in terms of the volumes of database on the level of a tree of the subgenus Pinus spp., the trans-Eurasian additive allometric model of biomass of trees for Eurasian forests are developed for the first time, and thereby the combined problem of model additivity and generality is solved. The additive model of tree biomass of Pinus is harmonized in two ways: it eliminated the internal contradictions of the component and the total biomass equations, and in addition, it takes into account regional differences of trees of equal sizes on total, aboveground and underground biomass. The proposed model and corresponding tables for estimating tree biomass makes them possible to calculate two-needled pine biomass (t/ ha) on Eurasian forests when using measuring taxation. © 2018 Plant Archives.
