Analysis of Litter Flammability of Common Tree Species During the Fire Prevention Period in Sichuan Province
To provide a theoretical basis for selecting fire-resistant tree species,litter samples were collected from 59 common tree species during the fire prevention period in Sichuan Province,and the litter load,moisture content,crude fat content,ignition point,heat value,and ash content were determined.Principal component analysis was used to evaluate the flammability of litter from different species.The results showed as follows:the litter load of different tree species was siqnificantly different,and the litter moisture content of different tree species was significantly dif-ferent.The tree species with higher litter flammability included Pinus densata,Cupressus funebris,and so on;the tree species with lower litter flammability included Ficus virens,Mangifera indica,and so on.Species with low lit-ter flammability could be selected as potential fire-resistant tree species.
