Abstract

For forest fire prevention and fire resistant tree species selection in Wuhan,we analyzed the flammability of leaves litter of common forest species in Wuhan and evaluated their combustion.We selected leaves litter of ten common forest species,Pinus massoniana,Pinus elliottii,Liquidambar formosana,Camphora officinarum,Quercus variabilis,Quercus chenii,Ilex chinensis,Camellia oleifera,Broussonetia papyrifera,Pittosporum tobira,measured seven flammability related variables,equilibrium moisture content,ignition point,ignition time,calorific value,ash content,lignin content and cellulose content.Cluster analysis and principal component analysis were used to divide the flammability of leaves litter into three grades:flammable,combustible and non-flammable,and to calculate a combustion index for each species.The results show that leaves litter of three species(P.elliottii, P.massoniana and Q.chenii)were classified as flammable,six species(I.chinensis, Q.variabilis, C.oleifera, P.tobira, L.formosana and C.officinarum)as combustible,and one species(B.papyrifera)as non-flammable.In the descending order,the flammability of the leaves litter of ten common forest species was P.elliottii, P.massoniana, Q.chenii, I.chinensis, Q.variabilis, C.oleifera, P.tobira,L.formosana, C.officinarum and B.papyrifera.B.papyrifera can be used as forest fire resistant tress species due to the non-flammable of its leaves litter.Forests with P.elliottii,P.massoniana or Q.chenii as the main component species are highly susceptible to fire due to the high flammability of their leaves litter,which should be a focus in forest fire prevention.

Key words： forest fires; leaves litter; combustibility; fire resistance; forest fire prevention; Wuhan City
