选具有代表性的10块华山松林标准地，采用数量化分类方法，取空中易燃可燃物最大密度、地表总易燃可燃物载量及地表易燃可燃物贮水量三个指标，对秦岭火地塘林区华山松林进行燃烧性分类。结果表明，该林区凡含有华山松的林分，其燃烧性最多可划分为9种类型，所选的10个林分类型归属其中的5类；相异性分析方法对森林燃烧性划分具有极好的分类效果。
Select the representative of 10 Chinese pine forest standards, the use of quantitative classification, take the maximum density of flammable air in the air, the total surface combustible combustible load and surface flammable combustibles storage of three indicators of Qinling fire The taxonomy of Huashan pine forests in Ditang forest area is classified. The results showed that all the forest species containing Pinus armandii in this forest area can be classified into 9 types at most, and the 10 types of forest types selected belong to 5 types. The analysis method of heterogeneity has extremely polar Good classification effect.
