以影响森林燃烧的各因子火险性的大小作为依据，综合控制林火发生的内因，可以从根本上剔除火灾隐患。通过对柞木林、柞桦林、山杨林、杨桦林、桦木林和水曲柳林等林型的燃烧性比较，及几种森林特征与燃烧性的关系的研究，结果表明，柞木林燃烧性较大，杨、桦、椴树林次之，水曲柳林安全可靠，同时也表明次生林在林分密度较大，林龄３０ａ左右；一天中１３～１５时燃烧性最高，从而为林火系统控制提供根据。 Based on the fire risk of various factors affecting the forest burning, comprehensive control of the internal causes of forest fire can eliminate the fire hazard fundamentally. By comparing the flammability of forest types such as oak forest, oak birch forest, poplar forest, birch forest, birch forest and ash forest and the relationship between several forest characteristics and flammability, the results showed that the flammability of oak forest Larix, poplar, basswood and linden forest were the second, and the second is the forest firewood system, which also showed that the secondary forest had a high stand density of about 30 years. Control provides basis.
