摘要
根据1953—2011年小兴安岭森林调查数据和森林火灾统计资料,结合野外火烧迹地调查与室内控制试验数据,估算了小兴安岭1953—2011年森林火灾的碳排放量和含碳气体排放量.结果表明:1953—2011年小兴安岭森林火灾的总碳排放量为1.12×107t,年均排放量为1.90×105t,约占全国年均森林火灾碳排放量的1.7%;其中,含碳气体CO2、CO、CH4和非甲烷烃(NMHC)的排放量分别为3.39×107、1.94×105、1.09×105和7.46×104t,相应年均排放量5.74×105、3.29×104、1.85×103、1.27×103t分别占全国年均森林火灾含碳气体排放量的1.4%、1.2%、1.7%和1.1%.不同林型的燃烧效率和单位过火面积的碳排放量均为针叶林>阔叶林>针阔混交林.最后提出了合理的林火管理措施.
Based on the forest resources investigation data and the forest fire inventory in 1953- 2011, in combining with our field research in burned areas and our laboratory experiments, this pa- per estimated the carbonaceous gases carbon dioxide （CO2）, carbon monoxide （CO）, methane （CH4 ） , and nonmethane hydrocarbons （NMHC） emission from the forest fires in Xiao Xing＇ an Mountains of Heilongjiang Province, Northeast China in 1953-2011. The total carbon emission from the forest fires in the Xiao Xing＇ an Mountains in 1953-2011 was 1.12×107 t, and the annual emission was averagely 1.90×105 t, accounting for 1.7% of the annual average total carbon emis- sion from the forest fires in China. The emission of CO2, CO, CH4, and NMHC was 3.39×107 , 1.94 ×105, 1.09 ×105, and 7.46× 104 t, respectively, and the corresponding annual average emis- sion was 5.74 × 105, 3.29 × 104, 1. 85× 103, and 1.27 × 103 t, accounting for 1.4%, 1.2%, 1.7% , and 1.1% of the annual carbonaceous gases emitted from the forest fires in China, respec- tively. The combustion efficiency and the carbon emission per unit burned area of different forest types decreased in order of coniferous forest 〉 broad-leaved forest 〉 coniferous broadleaved mixed forest. Some rational forest fire management measures were put forward.
