Pyrolysis characteristics of litter of eight tree species in Nanchang were studied based on thermogarvimetric analysis results. Three components of flammability of the eight species, i.e. ignitibility, combustibility and sustainability, were evaluated by pyrolysis parameters obtained from the analysis. Results showed that the eight species could be grouped into two categories: the first one included Camellia oleifera and Cinnamomum camphora, which were highly ignitable but low combustible and sustainable, the other included Cedrus deodara, Liriodendron chinensis, Phyllostachys heterocycla, Cinnamomum burmanni, Osmanthus fragrans and Ginkgo biloba, which were low ignitable but highly combustible and sustainable. This further indicated that rankings by each flammability component were usually not identical, showing the complexity of flammability and necessity of multi-dimensional flammability evaluation. Three-dimensional flammability evaluation could reflect different profiles of the feature and aid better understanding and explanation of fire behavior.
基于热重分析结果，研究了南昌市8种树木凋落物的热解特性。通过分析获得的热解参数评估了这8个树种可燃性的三个组成部分，即可燃性、燃烧性和持续性。结果表明，这8个树种可分为两类：第一类包括油茶和樟树，它们易燃但燃烧性和持续性较低；另一类包括雪松、鹅掌楸、毛竹、阴香、桂花和银杏，它们不易燃但燃烧性和持续性较高。这进一步表明，各可燃性组成部分的排名通常不相同，显示了可燃性的复杂性以及多维可燃性评估的必要性。三维可燃性评估可以反映该特征的不同概况，并有助于更好地理解和解释火灾行为。
