Impact of forest structure to biomass allocation 

quantifying the relationship between the structural parameters of forest stand with different types of silvicultural practies and increment of biomass, the effect of stand structure on the allocation of carbon in aboveground and belowground organs of tree and soil, modeling of forest growth from individual trees to the forest complexes undetr the influence of global chance, forestry, silviculture, leaf area index, biomass allocation, carbon content, carbon sequestration, competition index, spatial relationship in forest
