大兴安岭兴安落叶松火烧死亡判别模型

Discrimination Model for Postfire Mortality of Larch in Daxing'anling Region

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％。

Relations between postfire mortality of larch and fire characteristics of the' 5·6' forest fire in Daxing'anling Region in 1987 are studied here with a linear discrimination model for predicting postfire mortality of the tree established. Factors involved in the model are: tree height. diameter at breast height. bark thickness at breast height. height of first dead branch and height of blackened trunk. The averaged accuracy rate of the model is 80%.
