Structure and dynamics of deciduous trees debris forest stands of northern macroslope of Khamar-Daban ridge (Sonth Pribaikalye)

Results of paleocrystic (2002-2005) accounts of sheets debris of Mountain ashes Siberian - Sorbus sibirica and Asian white birches - Betula platyphylla in radical afforestations of northern macroslope of Khamar-Daban ridge (Sonth Pribaikalye) are analysed. Structure of sheets debris, intensity and terms of its accumulation in soil are revealed. The degree of participation of sheets debris of Sorbus s and Betula p. are shown in total annual debris sum, and also its comparative estimation with sheets debris mass of Cedar Siberian - Pinus sibirica and Firs Siberian - Abies sibirica is given. Year dynamics of sheet debris fraction accumulation and its spatial variations is characterized.
