- Аннотация: The intensity of biological cycling in urban park stands is assessed based on the following characteristics of the structure and functioning of forest litters: total litter stock, the stock and share of detritus in theL horizon, stock and share of easily degradable components (EDCs) in the L horizon, ratio of the stock inthe L horizon to the total stock in underlying horizons, ash content in L horizon, and EDC ash stock and itsshare in the total ash stock in the L horizon. The study has been conducted in the Bitsevsky Park underspruce, birch, and linden stands. The examined urban stands considerably differ from the natural ones in thecomposition of the living ground cover, which contains meadow and weed–ruderal species, suggesting ananthropogenic impact. The urban stands differ from the natural ecosystems by an increased intensity of biological cycling, which is indicated by total stocks and shares of detritus, EDCs, and ash of EDCs in the L horizon. Under urban conditions, the litter of coniferous stands is simple in its structure, thin (no thicker than 4–5 cm), and contains more ash in its individual components (over 10%), which reflects a considerable contribution of the mechanical migration of solid particles of different origins. In the majority of characteristics,the litter of deciduous urban stands is less different from the analogous natural litter as compared with the litter of coniferous urban stands. Correspondingly, the litter under spruce stands may act as an indicator ofanthropogenic impact on urban ecosystems. In general, the characteristics of biological cycling associatedwith the specific forest litter features suggest an increased intensity of biogenic migration as compared withthe analogous natural phytocenoses. This should be taken into account when predicting the development ofgreen urban landscapes.
