以东北“三大硬阔”为研究对象,采用外业调查和室内控制环境燃烧实验相结合的方法,分别对3种树木的枝、皮和干部进行气体排放量的测定,并对比分析不同树种及部位气体排放量的差异,通过计算分别得出CO2、CO、CxHy、NO和SO2气体的排放因子。研究结果显示:3种乔木各部位(枝、皮和干)之间CO2排放量、CO排放量、CxHy排放量、NO排放量、SO2排放量和含碳气体(CO2、CO和CxHy)总量以及5种气体(CO2、CO、CxHy、NO和SO2)总量平均值都存在差异,但差异显著性不相同;3种乔木燃烧皮部与干部的C0排放量、CxHy排放量、NO排放量以及SO2排放量平均值存在显著的差异(P〈0.05),而CO2排放量、含碳气体(CO2、CO和CxHy)总量以及5种气体(CO2、CO、CxHy、NO和SO2)总量平均值差异不显著;而枝部CO排放量与NO排放量3种乔木之间差异不明显;胡桃楸、水曲柳和黄菠萝的各部位的CO2平均排放因子分别为2.9608、3.0682和2.6492,CO、CxHyNO和S02的排放因子都比CO2要小很多。
以東北“三大硬闊”為研究對象,採用外業調查和室內控製環境燃燒實驗相結閤的方法,分彆對3種樹木的枝、皮和榦部進行氣體排放量的測定,併對比分析不同樹種及部位氣體排放量的差異,通過計算分彆得齣CO2、CO、CxHy、NO和SO2氣體的排放因子。研究結果顯示:3種喬木各部位(枝、皮和榦)之間CO2排放量、CO排放量、CxHy排放量、NO排放量、SO2排放量和含碳氣體(CO2、CO和CxHy)總量以及5種氣體(CO2、CO、CxHy、NO和SO2)總量平均值都存在差異,但差異顯著性不相同;3種喬木燃燒皮部與榦部的C0排放量、CxHy排放量、NO排放量以及SO2排放量平均值存在顯著的差異(P〈0.05),而CO2排放量、含碳氣體(CO2、CO和CxHy)總量以及5種氣體(CO2、CO、CxHy、NO和SO2)總量平均值差異不顯著;而枝部CO排放量與NO排放量3種喬木之間差異不明顯;鬍桃楸、水麯柳和黃菠蘿的各部位的CO2平均排放因子分彆為2.9608、3.0682和2.6492,CO、CxHyNO和S02的排放因子都比CO2要小很多。

The three broadleaved species (Juglans mandshurica, Fraxinus mandshurica, PheUodend onamurense) in Northeast China were used as study objects and the methods of field investigation and indoor combustion experiments in controlled environments were used to measure the gas emissions of tree branches, barks, and trunks, respectively. The gas emissions by species and tree parts were compared and analyzed and gas emission factors of CO2 , CO, CxHy, NO and SO2 were computed, respectively. The resuits showed that there are differences in the average gas emissions in CO2 emissions, CO emissions, CxHy emissions, NO emissions, SO2 emissions, the total carbon-containinggases (CO2, CO, CxHy) , and the total of five gases (CO2, CO, Cxny, NO, SO2)by different tree components (branches, barks, trunks), however, the significance of the differences are not the same. The average CO emissions, CxHy emissi.ns, NO emissions, and SO2 emissions in burning barks and trucks of the three species are significantly different ( P 〈 0. 05 ) , while the differences of CO2 emissions, carbon-containing gases ( CO2 , CO, CxHy ) , and total gas emissions (CO2 , CO, CxHy, NO, SO2 ) are not significant. There are no significant differences in CO and NO emissions during branch burn- ing among the tree species. The average CO2 emission factors of Juglans mandshurica, Fraxinus mandshurica, PheUodend onamurense are 2. 6492, 3. 0682, 2. 9608, respectively. The emission factors of CO, C.Hy , NO, and SO2 are dramatically smaller than that of CO2 emissions.
