| Summary: | The development of renewable energy is one of the principal areas of decarbonization of the energy sector of Ukraine, including in forestry. Improving the efficiency of using wood biomass for energy purposes, along with providing an appropriate level of technological processes and technical equipment, requires reliable information tools for managerial decision-making. An essential component of this toolkit is regional assessments of the energy function of forest phytocenoses. The information base of this study included information from the database of Industrial Association “Ukrderzhlisproekt”, which contains a specific inventory characteristic of tree stands of the region under study, as well as a system of mathematical models for quantitative assessment of phytomass and mortmass of forests. As a result, quantitative values of the total energy intensity of phytomass and mortmass of the forests of Zhytomyr Polissia were established. The total amount of energy accumulated in the plant biomass of the region’s forests is 3,035.7 PJ, which is equivalent to 100.2 million tonnes of conventional fuel. At the same time, the share of the total energy intensity of mortmass is 11.1%. The structure of the energy intensity of plant biomass in the region is dominated by pine stands, which accumulate over 60% of the energy of the forests of Zhytomyr Oblast, namely 70.8% – in the phytomass of tree trunks. Over 40% of the energy is accumulated in the plant biomass of stands of the site index class I, which mainly grow in relatively poor forest conditions (subors). In the overall structure of the energy intensity of the mortmass (336.2 PJ), more than 60% belongs to the forest floor (212.8 PJ), but it is not considered as a source of renewable energy, dry matter – 12.3% (41.3 PJ), dry branches – 17 .8% (almost 60 PJ). The results obtained in this study will serve as an information basis to devise a strategy for the development of forest bioenergy in the Zhytomyr region |
