Аддитивные региональные модели фитомассы деревьев и древостоев Eвразии. Сообщение 1: род Larix Mill.

Аддитивные региональные модели фитомассы деревьев и древостоев Eвразии. Сообщение 1: род Larix Mill.

Abstract

Впервые на уникальных по объёму базам фактических данных о фитомассе деревьев и древостоев на примере рода Larix Mill. разработаны трансевразийские аддитивные модели фитомассы лиственницы, и тем самым решена совмещенная проблема аддитивности и всеобщности моделей. Модель фитомассы деревьев гармонизирована двояко: в ней устранена внутренняя противоречивость «фракционных» и общего уравнения, и кроме того, она учитывает региональные различия равновеликих деревьев как по величине общей, надземной и подземной фитомассы, так и по ее фракционной структуре. Аддитивная модель фитомассы древостоев гармонизирована также по двум уровням, один из которых обеспечивает принцип аддитивности фракций фитомассы, а второй связан с вводом «фиктивных» переменных, локализующих модель по экорегионам Евразии. Модель демонстрирует различия фитомассы древостоев не только по абсолютным ее значениям для стволов, хвои, ветвей и корней, но и по их соотношениям, т.е. по структуре фитомассы. Предложенные модели и соответствующие таблицы для оценки фитомассы деревьев и древостоев лиственницы дают возможность определения их фитомассы в различных экорегионах Евразии по данным измерительной таксации. When using the unique in terms of the volumes of databases on the levels of a tree and stand of the genus Larix Mill., the trans-Eurasian additive allometric models of biomass of trees and forests for Eurasian larch 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 Larix 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 not only on total, aboveground and underground biomass, but also on its component structure, i.e. it reflects the regional peculiarities of the component structure of tree biomass. The additive model of forest biomass of Larix is harmonized in two levels too, one of which provides the principle of additivity of biomass components, and the second one is associated with the introduction of dummy independent variables localizing model for eco-regions of Eurasia.
