Carbon absorption ability of pine forest plantations in Kyiv Polissya

Purpose. Develop mathematical dependences of conversion coefficients to establish the accumulation of phytomass and volumes of absorbed carbon by pine forest plantations of Kyiv Polissya by age, using the methods of domestic and foreign scientists. Methods. In order to establish the carbon absorption capacity of pine plantations Kyiv Polissya in state-owned enterprises: Ivankov Forestry, Polissya Forestry, Teterysh Forestry temporary plots have been laid. According to the procedures P.I. Lakida, A.A. Storochinskogo, A.I. Poluboyarinov, A.C. Atkin, A.J. Bard phytomass pinetums installed in an absolutely dry state and obtained conversion coefficients are allowed to evaluate the difference between the CO2 emissions and carbon absorption. Results. Among thirty main forming species in Ukraine Scots pine (Pinus sylvestris L.) is the dominant tree species, particularly in the Kiev Polissya an area of 211.2 thousand hectares (61% of all tree plantations). According to the analysis of the distribution of areas of forest land areas for pine plantations in Kyiv Polissya, the overwhelming majority is occupied by pine forests of IІ and IV category (operational, recreational and health) are their share — 78%, so their carbon absorption capacity is significant. The resulting empirical equation exponential regression established that pine forests Kiev Polissya operating in its phytomass accumulated 1.21 million tons of carbon, and recreation and fitness — 1.17 million tons. Conclusion. Pine forests Kiev Polissya annually absorb carbon 16.0—21.0 tons of air that is approximately 0.3—0.7% of the annual carbon emissions.
