Estimativa de biomassa de plantios de eucalipto no Brasil

摘要

The aim of this work was to model growth of eucalypt plantations in Brazil. It was intended to evaluate influence of key climatic variables on eucalypt productivity. The database employed was obtained from the Soil and Eucalypt Nutrition Program of the Soil Department of the Federal University of Vi?osa. Climatic characteristics and age were a model important component. The region with the highest productivity produced three times more aboveground biomass than the poorest region. Regions with low water availability exhibited the lowest biomass production. Strong reduced in canopy proportion was observed within 3.5 years following planting. After that the canopy proportion reduced more slowly.
