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-containing gases and emission factors when combustible material coming from fourteen main arbor trees combust via emission 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

The CO 2 emission factors of each tree species are significantly higher than other gases. The average value of CO 2 CO C x H 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 is 5802.54mg 1398.18mg 82.06mg. The average total emission amount of carbon-containing gases is 7282.78mg.
