在对各省火灾统计资料和生物量估计的数据基础上，用排放因子法和排放比法，得出中国森林火灾释放的CO2、CO和CH4年平均分别为8.96Tg C/a、1.12Tg C/a和0.109Tg C/a，其中林下植物和地表枯落物的贡献分别为39%、47%和40%。各省年平均森林火灾释放的CO2、CO和CH4量主要是由火灾受害面积决定的，森林火灾较多的黑龙江、云南和内蒙古的这3种气体的排放量占全国的80%以上。森林火灾释放的CO2和CH4分别为全国所有源排放的1.2%和0.35%。中国年平均森林火灾释放的CO2、CO和CH4量分别为全球森林火灾排放量的0.3%、0.5%和0.01%。

Based on the data of forest fire accounting and biomass estimation for every pro vince,and employed emission factor method and emission ratio method,we estimate d the amount of CO2、CO and CH4 released from forest fires to be 8.96Tg C/ a、1.12Tg C/a and 0.109Tg C/a,of which the components of undergrowth and lit ter contributed 39%,47% and 40%,respectively.For each province,the amounts of CO2,CO and CH4 emission were dominantly determined by fire area.The cont ribution from Heilongjiang,Yunnan and Neimenggu provinces were more than 80% w h ere fire occurred very frequently.CO2 and CH4 emissions from forest fire acc ounted 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.
