tailieunhanh - Carbon Sequestration in Forest Ecosystems

Forest ecosystems cover large parts of the terrestrial land surface and are major components of the terrestrial carbon (C) cycle. Most important, forest ecosystems accumulate organic compounds with long C residence times in vegetation, detritus and, in particular, the soil by the process of C sequestration. Trees, the major components of forests, absorb large amounts of atmospheric carbon dioxide (CO2) by photosynthesis, and forests return an almost equal amount to the atmosphere by auto- and heterotrophic respiration. However, a small fraction of C remaining in forests continuously accumulates in vegetation, detritus, and soil. Thus, undisturbed forest ecosystems are important global C sinks | Klaus Lorenz X V Rattan Lal lAW iáSOĩỉ o Ễ ấ 3 i Sequestration in Forest Carbon Sequestration in Forest .
