【 摘 要 】

The article discusses the dynamics of decomposition of dominant plant species in mire complexes of the southern taiga of Western Siberia. The decomposition of plant remains in bogs occurs in the warm season, when the level of bog water decreases, and oxygen freely penetrates into the upper layer of the peat. The highest rate of decomposition is observed for Menyanthes trifoliate L., both leaves and rhizomes, losses of up to 80% of the initial mass during two years of experiment. The roots and stem bases were slowest to decompose: a 20% loss during two years. Sphagnum mosses lose from 20 to 40% of the initial mass in the same period.
