Characteristics of carbon-containning gases release during combustion of main arbor in Heilongjiang Province of China

摘要

Based on the study on spatiotemporal pattern of fires in forestry areas in Heilongjiang Province of China, outside field investigation is combined with indoor experiment to calculate the emission amount of carbon-containning gases and emission factors when combustible material coming from fourteen main arbor trees combust via emisson factor method in forestry areas in Heilongjiang Province. The results showed that CO_2 is the main components generated by combustible material of trees when they burn. The emission amount of carbon-containning gases remain diverse when different tree species combust but to varying degrees. The average value is 54531.82, 14612.08, 1269.27 respectively. The CO_2 emission factors of each tree species are significantly higher than other gases. The average value of CO_2, CO, C_xH_y factors are 2.6827 g·kg~(-1), 0.5800 g·kg~(-1), 0.0264 g·kg~(-1) respectively. The average value of emission amount given off by five kilogram test sample are 5802.54mg, 1398.18mg, 82.06mg. The average total emission amount of carbon-containning gases is 7282.78mg.
