Fire plays an important role in Northeast China forests,The occurrence of fires isclosely related to the environmental characteristics.High temperature,drought,and strong wind inspring(March to July)and autumn(September to November)are common fire climatic character-istics in Northeast China.Based on the chemical and physical characters of fuels,fuel quantity dis-tribution,sites as well as fire potential behaviour,fourteen fuel types have been classified inNortheast China Forest area.The fire adaptation of several main tree species has been also analysedin this paper.These species are widely distributed and of great economic significance in NortheastChina.Fire use is paid much more attention recently.Fire have been employed in many silviculturepractice such as fireline creation,fuels reduction and seed bed preparation in Northeast China
