昆明西山森林公园地表可燃物类型划分与载量研究

摘要

分析森林能否被引燃、如何蔓延以及整个火行为的过程中,森林可燃物比任何其他因素都重要.而可燃物载量的大小直接决定了森林火灾燃烧的强度,同时不同的可燃物类型会形成不同的燃烧特性.通过对昆明西山森林公园8个林分类型的地表可燃物载量、类型进行调查后发现,华山松林内地表可燃物栽量最高,农田-果园最低.并利用植物群落分类法将可燃物划分为5个类型组共6个类型.%Forest combustible is the most important factor when analyzing forest fire behavior including whether forest can be ignited and how the forest fire can be spread etc. However, the size of combustible capacity directly determined the burning intensity of forest fire, at the same time different combustible types could form different combustion characteristics. After investigation on combustible types and capacity of forest surface at eight forest stand, results showed that the highest combustible capacity of forest surface was in Pinus armandii forest, while the lowest was in Quercus acutissima forest. Combustible could be classified into five categories including six types according to the plant communities' classification.
