Biologically conditioned traits of individual forest tree species (especially growth rate, both intraspecific and interspecific competition ability, shading tolerance, vitality, sprouting capacity, natural regeneration ability etc.) are the basic criterion for their use in forest stands. Soil-improving and reinforcement function of forest tree species, especially its effectiveness, is contingent not only on their quantitative composition, but also on their both structure and texture allocaton inforest ecosystems. In paper presented, there is taken a course both to soil-improvng and reinforcement function of forest tree species, and to problems of appropriate way to create stand mixtures, in connection with need to ensure desirable diversity of forest treee species.
