摘要

The article presents the results of long-term (40-45-year) studies of vegetation restoration and mycorrhizal associations in recultivated and non-recultivated areas of the ash dump of the Verkhnetagil state district power plant (VT GRES) (Verkhny Tagil, Middle Urals). It is shown, that recultivation measures (covering the ash with strips of soil) accelerate the formation of forest phytocoenoses with domination of early successive species: Betula pendula Roth, Populus tremula L., Pinus sylvestris L. By the age of 20-30 years old late species appear in forest communities: Picea obovata Ledeb., Larix sibirica Ledeb., Abies sibirica Ledeb., Pinus sibirica Du Tour. On non-recultivated areas of the ash dump, vegetation restoration is delayed by 10-15 years: by the age of 35-40 years, forest phytocoenosis is formed with the prevalence of P. tremula, Betula pubescens Ehrh., B. pendula, with undergrowth P. sylvestris and P. obovata. With increasing age of plant communities, there is an increase in the number and proportion of mycorrhiza species. Most of the species growing in the conditions of the ash dump are weak mycotrophic. Indicators of mycotrophy are lower than in natural plant communities. By the age of 40-45 years, a wide range of mycorrhizal associations (types of mycorrhiza) characteristic of forest plant communities of the boreal zone are formed in plant communities at the ash dump of the Verkhnetagilskaya power station. The diversity of the spectra of mycorrhizal associations is largely determined by the zone-climatic conditions, and also depends on the edaphic features and recultivation measures.
