К синтаксономии искусственных лесов города Курска

Abstract

Geobotanical survey and classification of communities of oak plantations of the city of Kursk has been carried out. The described phytocoenoses are attributed to the non-rank community Fraxinus pennsylvanica–Quercus robur within the order Carpinetalia betuli, whose species are most represented in the coenoflora of this syntaxon. Variants with thr differences in the species composition and habitat conditions have been established in the community: typica, Lonicera caprifolium, Robinia pseudoacacia. Lonicera caprifolium is dominant in the phytocoenoses of var. Lonicera caprifolium and has the characteristics of an aggressive invasive plant. It forms a dense cover in the grass layer and suppresses shrubs and woody growth. Communities of var. Robinia pseudoacacia are characterized by a high closeness of the crowns of the shrub layer formed by Robinia pseudoacacia. The grass layer in them is poorly developed due to the allelopathic effects of this invasive species. The conducted research makes it possible to assess the current state of the artificial forests of the city of Kursk and monitor changes in their composition and structure.
