บทคัดย่อ

This study focuses on the fire characteristics and carbon mass balance of dead leaves open burning from prescribed fires in mixed deciduous forest (MDF) in Ratchaburi Province, Thailand. The leaf litter fuel load and leaf litter consumed in MDF was 5.31ฑ1.51 and 3.23ฑ1.87 t/ha respectively. The only top layer of biomass fuel was burnt due to the compactness and the leaf litter load is composed of a mixture of tree and bamboo leaves that the later had low heating value. In addition, the combustion factor of leaf litter burning was lesser than 60% and the low level of fireline intensity was 42 kW/min. Carbon analysis in leaf litter fuel consumed and residues after burning was 120.68ฑ40.38 and 11.81ฑ0.44 gC/m2. The amount of carbon output to oxidize to the atmosphere was 108.87ฑ39.95gC/m2 that is 11 times higher than residues after burned. Mixed deciduous forest fires released carbon into the atmosphere for more than 90% of carbon in leaf litter consumed and 10% of carbon on ground soil by residues after burnt form.
