Abstract
The results of research allowed to estimate the energy potential of pine (Pinus sylvestris L.) and black locust (Robinia pseudoacacia L.) plantations in stands located in Northern Steppe. The area of pine plantations in the investigated region is 21,472.2 ha (32.5 % of the area covered by forest vegetation) and black locust stands is 17,683.7 ha (26.9 % of the area covered by forest vegetation). The general values of aboveground phytomass components were evaluated in the context of the age structure of the plantations. Carbon sequestration by biomass components such as wood and bark of trunks, branches, foliage mass were calculated in different age groups. The main reservation of carbon pools for both studied species are the middle-aged stands of 41–60 years old. They accumulate 1,019.78 thousand ton for for pine and 675.16 thousand ton for black locust. In the component structure of aboveground phytomass, the stem wood contribute dominatly to the total carbon sequestration; the share is 81.6 % for pine stands and 65.9 % for black locust stands. The main carbon pools were examined in the different components of aboveground phytomass of pine and black locust plantations. The results of the evaluation of the energy content in the aboveground phytomass is given. The energy potential of the carbon accumulated in the pine stands phytomass reaches 40,556.84 GJ and it is 32,188.14 for black locust stands.
