Recovery of tree stand after clear-cutting in the ural mountains

摘要: For the mountain forests of Middle Urals (Russia) recovery tree stand after clear-cuttings was studied. Two options drained habitats have been studied: steep slopes southern exposition with small stony soils and lower parts gentle thick soils. description biomass dynamics pine (Pinus sylvestris L.) birch (Betula pendula Roth, B. pubescens Ehrh.), their interference in course forest formation were constructed on basis systems that connected logistic equations model coexistence. We developed mathematical descriptions two alternative ecodynamic series vegetation clear-cutting: regeneration initial (after cuttings cowberry shrub forests) long-derivative grass-reed grass forests).
