Дистанционная регистрация таких таксационных показателей деревьев, как ширина кроны и высота дерева, получила широкое распространение при оценке биомассы деревьев. Имеется множество аллометрических моделей биомассы разных древесных пород в разных климатических условиях, но для оценки биомассы дистанционными методами они представлены единичными публикациями. В исследовании использована авторская база экспериментальных данных 249 модельных деревьев Fagus L. и 78 деревьев Fraxinus L. Евразии с замеренными показателями высоты дерева, ширины кроны, а также биомассы ствола, листвы, ветвей и корней. Для всех компонентов надземной биомассы установлена положительная связь с шириной кроны и высотой дерева. Составлены двухвходовые таблицы для таксации биомассы двух древесных родов. Полученные результаты дают представление о том, насколько может различаться структура биомассы равновеликих деревьев таких пород, как бук и ясень, может ли эта структура изменяться в градиенте зимних температур Евразии и каким может быть вклад климатической переменной в объяснение изменчивости биомассы деревьев.

Remote registration of such taxation indicators of trees as crown width and tree height has become widespread in assessing the biomass of trees. There are many allometric models of the biomass of different tree species in different climatic conditions, but for the assessment of biomass by remote methods, they are presented in single publications. The authors used the experimental data base of 249 and 78 model trees of Fagus spp. and Fraxinus spp. correspondingly with measured indicators of tree height, crown width, as well as the biomass of trunk, foliage, branches and roots. For all components of aboveground biomass, a positive relationship was established with the crown width and the tree height. Two-input tables for the taxation of the biomass of two genera are compiled. The results obtained give an idea of how much the biomass structure of equal-sized trees of such species as beech and ash can differ, whether this structure can change in the winter temperature gradient of Eurasia, and what can be the contribution of the climate variable to the explanation of the variability of tree biomass.
