Characteristics of gas release during combustion of main arbor and shrub species in Xiaoxing''an Mountain
小兴安岭主要乔、灌木燃烧过程的烟气释放特征

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 1277.04 and 1149.06 mg x g(-1), 1476.27 and 1147.18 mg x g(-1), and 1486.21 and 1459.67 mg x 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 x g(-1), 3.61 and 5.03 mg x g(-1), and 6.32 and 7.46 mg x 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.
