In the past, the forest management was based on the theory of hinges, according to which the non-productive role of the forest can best be ensured in the veil behind the production of wood raw material, as an automatic effect of the forest ecosystem management. The hinge theory states that the production of wood and the fulfillment of others non-production functions of forests is identical or at least parallel. However, this opinion disappeared in the result of the forest management development by its intensification and increased social demand after the non-production functions of forests. Solving the problem between forest production and other non-forest production functions requires a detailed examination of individual relationships. Therefore, the aim of this thesis is assessment of the relationships between individual forest functions expressed by selected indicators of the given function with the use of the SIBYLA growth simulator and the method of interactive decision maps. For the purposes of research, we have predicted the development of homogeneous equatorial stands consisting of beech until the age of 100, when begins the recovery phase in case of most woody plants. We used the results of the growth simulator as indicators of the fulfillment of the given function of the forest and displayed them through two-dimensional decision maps. We have assessed the relationships between individual indicators of forest function fulfillment using two-dimensional decision maps, whereby we have found that there are indicators complementary and mutually competitive, where it is not possible to ensure a high value of indicators at the same time, but compromise solutions need to be sought.
