Based on field investigation, the burned areas and consumed fuel loadings in Daxing' anling region caused by forest fires in 2005-2007 were estimated by comparing the normalized difference vegetation index (NDVI) before and after burning. The burned areas were classified with fire intensity, and the carbon emission from the fires was estimated by the fuel consumption and the average carbon content of plants. It was estimated that the total burned area was 436512. 5 hm2, of which, the severe, moderate, and light burned areas occupied 207178.4, 150159.2, and 79159.4 hm2, respectively. The consumed fuel loadings were 3.9 x 10(6) t in total, and the emitted carbon was 1.76 x 10(6) t, with 0.34 x 10(6), 0.83 x 10(6), 0.27 x 10(6), and 0.32 x 10(6) t from larch (Larix gmelini) forest, conifer and broadleaves mixed forest, broad-leaved forest, and grassland, respectively.
基于实地调查,通过比较火烧前后的归一化植被指数(NDVI),估算了2005 - 2007年大兴安岭地区森林火灾造成的过火面积和消耗的燃料负荷。根据火灾强度对过火面积进行分类,并通过燃料消耗和植物平均碳含量估算火灾的碳排放量。结果表明,总过火面积为436512.5公顷,其中重度、中度和轻度过火面积分别为207178.4公顷、150159.2公顷和79159.4公顷。消耗的燃料负荷总量为3.9×10⁶吨,排放的碳为1.76×10⁶吨,其中落叶松林、针叶阔叶混交林、阔叶林和草地排放的碳分别为0.34×10⁶吨、0.83×10⁶吨、0.27×10⁶吨和0.32×10⁶吨。
