| 摘 要： | 通过烟气分析系统测定小兴安岭地区15种森林可燃物类型地被物未分解层和半分解层燃烧过程中CO2,CO,CxHy,NO和SO2的排放因子和释放量,并分析不同可燃物类型的排放差异性和5种气体的相关性.结果表明:15种可燃物类型地被物燃烧5种气体的排放因子分别为3.16,0.31,0.007 0,0.005 4和0.019;5种气体总量、含碳气体总量和C02的释放总量分别为:1 330.56,1 321.25和1 200.56 mg·g-1,且均为半分解层大于未分解层;而CO,CxHy,NO和SO2的释放总量分别为:118.02,2.66,2.06和8.21mg·g-1,半分解层均小于未分解层;CO2,CO,CxHy和SO2的释放量之间存在着极显著的相关性(P＜0.01),而NO与这4种气体之间无显著相关(P＞0.05).研究结果将为评价森林火灾对大气环境造成的影响以及森林地被物的管理提供一定的科学依据.

| Abstract: | The release amounts and emission factors of CO2,CO,CxHy,SO2 and NO from the combustion of fifteen types of fuels in un-decomposed layer and semi-decomposed layer in Xiaoxing'an Mountain were determined by using the gas analysis system. We also analyzed the differences in the release amounts of fifteen types of fuels and the correlation of five gases from the combustion. The results showed that the factors of the five emitted gasses from fifteen types of fuels were respectively 3.16,0.31,0.007 0,0.005 4,0.01... |
