摘要:

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8.96TgC/a、1.12TgC/a和0.109TgC/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%。

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.
