摘要: 测定了小兴安岭林区凉水林场10种乔木和9种灌木可燃物燃烧过程中释放的CO2、CO、xHy、SO2和NO等气体含量,计算了不同可燃物的气体释放量及排放因子.结果表明:乔木和灌木可燃物试样燃烧过程中释放的CO2、含碳气体总量和5种气体总量的平均值分别为1 277.04和1 149.06 mg·g-1、1 476.27和1 147.18 mg·g-1、1 486.21和1 459.67 mg·g-1,乔木均大于灌木;乔木和灌木的CO、NO和SO2释放量平均值分别为231.58和282.93 mg·g-1、3.61和5.03 mg·g-1、6.32和7.46 mg·g-1,灌木均大于乔木;乔木和灌木的CO2、CO排放因子分别为2.8853和2.7718、0.4558和0.2425,乔木大于灌木.

Abstract: The amounts of CO2, CO, CxHy, SO2 and NO released from the combustion of 10 arbor and 9 shrub species in Liangshui Forest Farm of Xiaoxing’an Mountain were determined, with the release amounts and emission factors of these gases calculated. The results showed that the released CO2, the total amount of carbon-containing gases, and the mean value of the total amount of the 5 gases during combustion were larger for arbors than for shrubs, being 1 277.04 and 1 149.06 mg·g-1, 1 476.27 and 1 147.18 mg·g-1, and 1 486.21 and 1 459.67 mg·g-1, respectively, while an opposite pattern of the mean release of CO, NO and SO2 was observed, being 231.58 and 282.93 mg·g-1, 3.61 and 5.03 mg·g-1, and 6.32 and 7.46 mg·g-1 for the arbor and shrub species, respectively. The emission factors of CO2 and CO were also larger for arbors than for shrubs, being 2.8853 and 2.7718, and 0.4558 and 0.2425, respectively.
