摘要
通过对大兴安岭地区1987年“5.6”大火后中幼龄樟子松个体死亡情况与火烧状况之间关系的研究,建立了该地区樟子松个体火烧后死亡状况的线性判别模型。判别因子包括个体的树高、胸径、胸高处皮厚、第一枯枝高和树干熏黑高度。模型准确率达80%。
Relationship between postfire mortality of Scotch pine and fire characteristics was studied based on the investigations of the fire site of '5.6' forest fire in Daxing'anling region in 1987. A linear discrimination model for predicting p ostfire mortality of this species was established. Factors involved in the model are tree height, DBH, bark thickness at breast height, height of first dead bra nch, and height of blackened trunk. The average accuracy rate of the model reach es 80%.
