本研究主要对俄罗斯西伯利亚下安加拉地区轻针叶林火灾后地表碳储量的结构进行了分析。在南部针叶松林和落叶松混交林进行了不同锋面强度的实验火灾。相当数量的地面和地面森林燃料(21-38tC ha−1)加强了低强度到高强度的火灾。火后碳储量随火势和蔓延速度的不同而降低16%~49%，烧伤深度为0.9~6.6 cm。碳排放量在4.48~15.89tha−1之间变化，这取决于火灾强度和森林类型。四个主要场地类型的烧伤深度和碳排放与基于天气的火灾危险指数相关。
This study focused on structural analysis of ground carbon storage following fires in light conifer stands of the Lower Angara region (Siberia, Russia). Experimental fires of varying frontal intensity were conducted at Scots pine and mixed larch forests of southern taiga. Considerable amounts of surface and ground forest fuels (21–38 tC ha − 1) enhanced low- to high-intensity fires. Post-fire carbon storage decreased by 16–49% depending on fire intensity and rate of spread, with depth of burn being 0.9–6.6 cm. Carbon emissions varied from 4.48 to 15.89 t ha − 1 depending on fire intensity and forest type. Depth of burn and carbon emissions for four major site types were correlated with a weather-based fire hazard index.
