The purpose of compression and high temperature thermal treatment with oi1 of 741 Populus wood was to improve mechanical properties and the dimensional stability. Results showed that the moisture content of Populus wood was decreased from 76%to 10%with compression temperatures of 160℃for 2 h and the compressive rate of perpendicular to grain of wood of 30%. then with high temperature thermal treatment with oi1 of 210℃for 2 h, after that, thickness swelling rate of water ab-sorption of the densified Populus wood 2 h and 24 h was largely decreased and the dimensional stability was greatly increased.
