Carbon Pools and Flux of Global Forest Ecosystems

摘要

Forest systems cover more than 4.1 x 10(9) hectares of the Earth's land area.Globally, forest vegetation and soils contain about 1146 petagrams of carbon, with approximately 37 percent of this carbon in low-latitude forests, 14 percent in mid-latitudes, and 49 percent in high latitudes. Over two-thirds of the carbon in forest ecosystems is contained in soils and associated peat deposits. In 1990,
