This work solve problems of forest cutting regulation using by methods of mathematical model at chosen working-plan area, forest user units and forest management units. From obtain number of working-plan area, forest user units and forest management units have been generated more groups on the base of determinate criteria. The second group was chosen for solution of problems of cutting regulation of forests. Age structure of the units is characteristics by different age class representation. Evaluation unevenness age structure of units was performed with using of index of variation and indexes of loss of variability. From analyze of indexes in individual units result, that the gradual regulation of age structure is possible reach of equal age structure. In watched working-plan area was value of indexes of variation of original age structures between 72.51% and 81.57% and reduced to 30.56%. In forest user units was value of coefficients of variation in original age structure between 63.79% and 86.91% and reduced to 30.27%. Similar course of index of variation we can observe in others chosen units, too. Proposed method has shown possibility of phased achievement equal age structure in the forest spatial distribution units.
