소나무류 수관층 및 지표층의 CO2/non-CO2 배출량 분석 연구

초록

In this study, we carried out the emissions analysis of CO and non-CO2 for the age-classes of various pine trees(Pinuskoraiensis, Pinus densiflora, Pinus rigida Mill., Pinus thunbergii Parl.) to estimate of emission factors of the crown layer and surface layer in theforest fire. We used the thermal characteristic analyzer cone heater and NDIR analyzer in order to measure amount of emission. As aresult, the major emissions of Pinus koraiensis were CO2 and CH4 and that of Pinus thunbergii Parl. was only CO. The majoremissions of the most of pine trees were NO and N2O. The CO2 emission of Pinus thunbergii Parl. was the highest about as7.26×10-2~1.63×10-1 g and next came Pinus densiflora, Pinus koraiensis, Pinus rigida Mill.. And the CO emission of Pinus thunbergiiParl. was about 5.14×10-3~6.58×10-3 g and followed by Pinus densiflora, Pinus koraiensis, Pinus rigida Mill.. The emissions of CH4,NO, and N2O showed small differences between species and the emission of CH4 was 8.37×10-5~2.55×10-4 g, and NO was6.65×10-5~2.0×10-4 g and N2O was 1.42×10-4~2.09×10-3 g in all species. Particularly, the emission of Pinus thunbergii Parl. was thehighest in all pine trees except CH4
