The study developed a system of mathematical models and obtained information and reference data to determine the phytomass of the structural components of trees and stands of robinia false acacia. Qualitative indicators of phytomass of trunk, crown and assimilation fraction of robinia trees are determined. Based on the results of the research, an algorithm for calculating annual production was developed and its evaluation for modal robinia stands was carried out. Ecosystem functions of robinia stands are estimated, regularities of accumulation of inorganic contaminants in aboveground phytomass in the conditions of polyelement pollution of soil by metals are established. Indicators of thermodestruction of phytomass of trunks are received, energy function of robinia stands is estimated. The total amount of accumulated organic plant matter, deposited carbon, oxygen produced by robinia stands of the Bayrach steppe of Ukraine is determined.
