摘要: The burned area, fuel type, crown fire percentage, and carbon release of the southern Siberia 2003 wildfire were analysed using AVHRR, MODIS, MERIS, ASTER images a model. More than 200 000 km2 from 14 March to 8 August 2003, which 71.4% was forest, 9.5% humid grassland, 2.15% bogs or marshes. During 1996 32.2% forested area 23.36% total burned, 13.9% affected by at least twice. Direct emission this around 400640 Tg. Siberian fires could well have contributed high increase atmospheric CO2 CO concentration in 2003. increasing human pressure coupled with intensive severity, recurrent frequency, occurrence summer droughts will reduce sequestration potential important pool.
