Фитомасса деревьев лиственниц сибирской и Гмелина: сравнительный анализ

It is revealed that the averaged estimation of fractional structure of larch tree biomass by the stem diameter and the tree height increases the standard error of determining the needle mass by 19%, branches by 30%, stems by 35% and aboveground biomass by 46% as compared to similar local (regional) estimation. That suggests the need for local standards for estimating larch tree biomass. In different ecological regions the fractional biomass structure of larch trees of equal sizes varies and biomass percentage of needles, branches and stems in the total aboveground biomass of equal trees reveals regional features. The proposed regional tables for estimating larch tree biomass may be used as a basis for calculating the biomass of larch forests in different ecological regions of Siberia and Northern Kazakhstan.
