Smoke Production Ability during Combustion of the Four conifer-tree species in Hei Long Jiang Province

摘要

The combustibility of four conifer-tree species in Xiaoxing'an Mountain, Heilongjiang Province was studied by cone calorimetric analysis. The four species were Pinus koraiensis Sieb.et Zucc, Pinus sylvestris var.mongolica Litv, Picea koraiensis Naked, Larix gmelinii Rupr.. The thermal characteristics of leaves and barks, including smoke production rate(SPR), specific extinction area(SEA), the concentration of carbon dioxide (CO2), the production of carbon dioxide (P
