Preliminary exploration and test of the main influential factors and relevant process parameters of the compressed modified wood made of Populus Tomentosa impregnated in UF resin are conducted and the effect of each factor on the production process and its performance is discussed based on experimental results.The results show that：（1）the order of the factors influencing wood performance from the primary to the secondary： compression ratio-pressing time-pressing temperature;（2）within the experimental parameter range,good process parameters are： hot temperature,140℃;pressing time,20min;compression rate,50%;（3）within the experimental parameter range,pressing time has a noticeable effect on the WPG,MC and resin retained rate of test pieces while pressing temperature has a significant effect on WGP and compression ratio has an evident effect on the density,deformation response rate,thickness swelling rate of test pieces.
