以大兴安岭林区兴安落叶松林、樟子松林和杨桦林中的草本、枯枝和半分解层为研究对象,采取外业调查取样及室内控制环境燃烧实验相结合的方法,分析了不同林型、不同可燃物燃烧过程CO2、CO、CxHy、NO和SO2释放量的差异。结果表明,草本燃烧CO2排放量阔叶林(杨桦林)大于针叶林(兴安落叶松林、樟子松),针叶林(兴安落叶松林、樟子松)枯枝CO2排放量大于阔叶林(杨桦林),而半分解层兴安落叶松林CO2排放量大于杨桦林和樟子松林。兴安落叶松林半分解层除NO释放量以外,其它四种气体与草本、枯枝无显著的差异。
Taking herbaceous, litter and semi-decomposed layers of Larix gmelinii forest, Pinus sylvestris var. Mongolica and Populus bryaucronii forest in Daxing’anling as study object, this paper analyzed the effects of different forest types, Differences in CO 2, CO, CxHy, NO and SO 2 Release During Combustion of Combustibles. The results showed that the CO 2 emission of the herbaceous plantation was larger than that of the coniferous forest (Larix gmelinii forest, Pinus sylvestris var. Mongolica) and the coniferous forest (Larix gmelinii forest, Pinus sylvestris var. Mongolica) than that of the broadleaf forest Yang birulin), while the CO2 emission of the Larix gmelinii forest in the semi-decomposed layer was larger than that of the poplar and Pinus sylvestris var. Mongolica forests. Larix gmelinii forest semi-decomposition layer in addition to the NO release, the other four gases and herbs, dead branches no significant difference.
