[Evaluation of three-dimensional flammability of eight forest fuels based on thermogravimetric analysis in Nanchang region, China].
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.
