Abstract:

Based on the data of forest fire accounting and biomass estimation for every province,and employed emission factor method and emission ratio method,we estimated the amount of CO₂、CO and CH₄ released from forest fires to be 8.96 Tg C/a、1.12 Tg C/a and 0.109 Tg C/a,of which the components of undergrowth and litter contributed 39 %,47 % and 40 %,respectively.For each province,the amounts of CO₂,CO and CH₄ emission were dominantly determined by fire area.The contribution from Heilongjiang,Yunnan and Neimenggu provinces were more than 80*!% where fire occurred very frequently.CO₂ and CH₄ emissions from forest fire accounted for only 1.2 % and 0.35*!% of total national emissions,respectively.CO₂,CO and CH₄　emissions from froest fire in China were 0.3 %,0.5 % and 0.01 % of global emission from forest fires.
