Pugachev А. А. Biological Cycle Components in Ecosystems оf Dwarf Siberian Pine оf the Upper Kolyma River Basin // Forest Science (Lesovedenie). 2011. No.1. P. 13-18 (in Russian). In the ecosystems of dwarf Siberian pine (Pinus pumila) of the Upper Коlуmа River Basin, the underground phytomass reserves amount to 26-43 t ha-1, the total plant stock is 92.45-151.49 t ha-1, and the annual increment is 1.3-3.8 ha-1 per year. The falloff reserves were determined at 1/30-1/42 of the total phytomass. The contents of ash elements in separate organs of dwarf Siberian pine, shrubs, and dwarf shrubs were determined. Some parameters of the biological сусlе of elements and ash are characterized. The annual consumption of chemical elements bу the Pinus pumila increment is 44-104 kg ha-1, and the amount of annually returning chemical elements with the falloff is much lower than their annual entering to the plants - 20.2-41.0 kg ha-1. Dwarf Siberian pine, biomass, increment, falloff, biological сусlе of elements. |
