【摘要】 以小兴安岭地区阔叶红松林下主要草本可燃物为研究对象,通过外业调查取样及室内控制环境燃烧试验,测定了42种主要草本可燃物燃烧过程中释放的CO2、CO、CxHy、NO、SO2的气体含量,计算了不同可燃物的排放因子及气体释放量。烟气分析结果表明:CO2、CO、CxHy、NO、SO2等5种气体的排放因子分别为2.930 1、0.459 9、0.013 9、0.008 7和0.022 7;试样燃烧过程中释放的5种气体总量的平均值分别为1 113.46、174.73、5.26、3.29和8.60 mg.g-1。CO2的排放因子和释放量均显著大于其他4种气体。聚类分析结果表明同一科内的草本植物具有相似的排放特性。更多还原

【Abstract】 Taking the main herbaceous fuels under broadleaved Pinus koraiensis forest of Xiaoxing’anling in Heilongjiang province as research object,through the method of wild investigation and laboratory burning experiments under controlled conditions,the amounts of CO2,CO,CxHy,NO,SO2 released from the combustion of 42 species of herbaceous fuels were determined;emission factors of different gases and their release amounts were calculated.Result of gas analysis shows that: emission factors of the main content of CO2,CO,CxHy,NO & SO2 are 2.930 1,0.459 9,0.013 9,0.008 7 & 0.022 7,respectively;emission quantity of CO2,CO,CxHy,NO & SO2 are 1 113.46,174.73,5.26,3.29 & 8.60 mg ·g-1,respectively.Emission factors and emission quantity of CO2 are greater than that of other 4 kinds of gases obviously.The cluster analysis result shows that the same family of herbs have similar emission characteristics.更多还原
