Abstract: During the heat treat of wood,it is important to forecast accurately the transient temperature distribution in wood for control effectively the heat stress and the distortion of structural element.This paper presented the basic theory for the analysis of wood transient heat conduction.Considering the thermal anisotropic,finite element method was used to simulate the temperature field.The distribution and variation rule during the heating process was also got.Through comparison numerical simulation solutions with testing experiment results,the simulation results are very consistent with the actual values.It is also proved that the method on wood heat conductivity is feasible and practical.

Key words: finite element, softwood, transient temperature distribution, numerical simulation
