通过对大兴安岭地区１９８７年５·６森林大火后中幼龄兴安落叶松个体死亡情况与火烧状况之间关系的研究．建立了该地区兴安落叶松个体火烧后死亡状况的线性判别模型。判别因子分别是：个体的树高、胸径、胸高处皮厚、第一枯枝高和树干熏黑高度。模型的平均准确率为８０％。
Through the Daxinganling area in 1987 5,6 after forest fire in young Larix gmelinii individual mortality and the relationship between fire conditions. A linear discriminant model was established for the death of Larix gmelinii in the area after fire. Discriminant factors are: the individual’s height, diameter at breast height thickened, the first dead branches and tree height blackened. The average accuracy of the model is 80%.
