摘　　要：应用排放因子法,对大兴安岭林区1980—2005年间森林火灾中不同林型下灌木、草本和地被物层气体释放量进行估算。结果表明:大兴安岭25年间森林火灾灌木、草本和地被物层CO2,CO,CxHy,NO,SO2的释放量分别为25.04×106,5.72×106,0.21×106,0.09×106和0.24×106t。其中白桦-落叶松林、白桦-杜鹃林和蒙古栎-胡枝子林是气体释放量较多的林型,约占总排放量的70%以上。此外大兴安岭林区森林火灾SO2和NO的释放量可达到我国总生物质燃烧释放量的50%左右,其释放量与农业上备受关注的秸秆燃烧相当。By using the emission factor（EF） method,this paper estimated the gases released from shrubs, herbages and litters layer between different forest type in Daxin＇ an Mountains during forest fires from 1980 to 2005. The result showed that the amounts of CO2, CO, CxHy, NO and SO2 released from shrubs, herbages and litters layer were 25.04 ×10^6, 5.72 × 10^6, 0. 21 × 10^6, 0.09 × 10^6 and 0.24 × 10^6 t respectively. Betula platyphylla-Larix gmelinii, Betula platyphyUa- Rhododendron simsii and Quercus mongolica- Lespediza bicolor were the main forest type for releasing the gases, accounting for more than seventy percent of total release. Additionally, the amount of SO2 and NO released from Daxin＇ an Mountains would make up fifty percent of biomass fuels in China, it was almost the same quantity as the crop residues that are extensively concerned in agriculture field.
