THE MODELS OF CONVERSION COEFFICIENS OF TREE STANDS PHYTOMAS'S COMPONENTS OF NATIONAL NATURAL PARK ''HOLOSIIVSKYI'

One of the largest forests territory in the capital of Ukraine is National natural park "Holosiivskyi". By accumulating organic mas, the park's forests carry out a number of ecological functions that ensure a normal functioning of the city. Oxygen production, stock of phytomass and deposited carbon in it are important indicators reflecting ecological functions of forests. The assessment of the carbon stock in the forest ecosystem at the regional level will enable us to characterize ecological functions of the NNP "Holosiivskyi" tree stands. According to the results of field and laboratory researches that were processed on the computer using special application programs (MS Exel table processor, statistic program SPSS Statistic Base 21) the database of temporary trial plots was collected and analyzed. The database was further used for developing of multiple regression equations of conversion rates of the NNP "Holosiivskyi" tree stands. Great number of conversion coefficients mathematical models phytomas's components of wood, bark, branches and leaves were investigated. Regressive equations of phytomas's components for pine, oak, hornbeam and alder were created. Received models ancount regional peculiarities of tree stand as well as their taxation structure.
