Estoque de carbono em cerrado sensu stricto do Distrito Federal

Abstract: RESUMO -O objetivo do trabalho foi estimar o estoque de carbono da parte aérea (troncos, galhos e serapilheira) e subterrânea (raízes e solo) da vegetação lenhosa de um cerrado sensu stricto, localizado na Fazenda Água Limpa, da Universidade de Brasília, Distrito Federal. A área de estudo foi amostrada a partir de parcelas de 20 x 50m alocadas sistematicamente. Em cada parcela foram inventariados todos os indivíduos lenhosos arbóreo-arbustivos, vivos e mortos em pé, com no mínimo 5 cm de diâmetro tomado a 30 c… Show more

“…To decrease the amplitude, average values per vegetation type were generated (Table 3), and the values are similar to those shown in other studies (IPCC 2006;Caldeira et al, 2008;Vieira et al, 2010;Froufe et al, 2011;Paiva et al, 2011;Ribeiro et al, 2011;Watzlawick et al, 2012;Morais et al, 2013;Torres et al, 2013) for various vegetation types. The differences among the averages for physiognomies correlated with the number of trees and biomass stock, which means the higher the values of these characteristics, the higher the stocks of biomass and C in the litter.…”

“…Deforestation is responsible for about 25% of annual atmospheric CO 2 emissions across the globe Faria, 2007). On the other hand, in Brazil, land use changes and deforestation are the main practices that contribute to soil carbon flow into the atmosphere, placing the country in fourth position, along with the United States, China and Russia, in the ranking of countries that emit the most CO 2 into the atmosphere (Matthews et al, 2014).…”

“…In several works, quantitative data can be found of carbon stock in several forest formations, such as humid tropical (NGO et al, 2013), woody savannas (PAIVA; REZENDE; PEREIRA, 2011;REZENDE et al, 2006) and temperate forests (THURNER et al, 2014). However, the few studies related to the quantification of carbon stocks in dry forests, compromises understanding of the process of CO 2 conversion in these ecosystems, underestimating its importance as a regulator of the carbon cycle.…”

“…O estoque médio de serapilheira observado na área de Cerrado Típico no presente estudo apresentou valor próximo ao verificado em uma área de Cerrado sensu stricto em Curvelo, MG, (6,46 t ha -1 ) (Paiva et al, 2011). No entanto, foi menor quando comparado com uma área de Cerrado Típico em Brasília, DF, (média de 7,11 t ha -1 ) Figura 1.…”
