| Abstract: | The carbon pool and emission of carbon dioxide from terrestrial ecosystems in Chinahave been estimated. The carbon pool is 2.51×109-25.2×109 ton C in vegetation, and 49. 7×109ton C in soil. The carbon dioxide release from terrestrial ecosystems is 0.0317× 109- 0. 195× 109ton C due to changes in land-use in recent years, mainly caused by deforestation and degradation ofgrassland. This carbon release due to changes in land-use is approximately 17% of the current carbondioxide emission from fossil fuel combustion and cement production in China. As compared withthe global carbon pool, the carbon pool in vegetation and in soil in China are 1.8% and 3.3% ofthe global figures, respectively |
