Carbon-removing ability of fir plantations of the Krasnoyarsk Territory forest-steppe zone

Abstract

Forest ecosystems play a global role in carbon sequestration and emission processes on a planetary scale. The topic of the functional ecological role of forests is urgent due to the problem of climate warming and an increase in the level of carbon dioxide concentration in the atmosphere. Currently, a differentiated (regional) approach to assessing the biological productivity of stands and their carbon-removing ability is important, which allows a detailed approach to organizing monitoring of the ecological balance and using the resource potential of forest ecosystems of a certain territory. The aim of this work was to assess the carbon-removing ability of modal stands of Siberian fir based on the study of the dynamics of the fractional composition of phytomass in the process of planting development. The studies were conducted in the conditions of the Central Siberian subtaiga forest-steppe region of the Krasnoyarsk Territory (the territory of the Bolshemurtinsky forestry). The object of research was fir stands of the third class bonitet. In the work, materials were used for eye-tracking taxation of 456 sections. The dynamics of the fractional composition was calculated using the conversion-volumetric method (Ph/M conversion) on the basis of the developed table of the growth course, followed by the conversion of the studied fir plantations to the carbon reserves deposited by the tree layer.
