摘要：Populus is one of the major forest plantation species in China with more than 6 million hm(2) of plantation forests. Wood composites made of plantation material play a very important role in balancing supply and demand of timber in China. This paper summarizes physical and mechanical properties, and chemical composition of this material. The key characteristics of wood composites made of Populus are: low density, light color, high and unevenly distributed moisture content, easy to deform, and high stress wood proportion. Populus plantation material is widely used to manufacture plywood, block board, particleboard, MDF, and reconstituted fancy veneer in China. And research and development of Populus plantation material in China is also introduced. This paper also suggests focusing on future Chinese market segmentation, particularly that: fast growing Populus species with high quality be further genetically improved, more intensive management be practiced in plantations (such as wider spacing, pruning, irrigation, fertilizing, and beetle prevention, aiming at large diameter, fewer and smaller knots, and low taper for veneer manufacturing), more technology improvements be made (veneer peeling and softening, drying and gluing technology to make better use of the material), new products be developed to meet new construction and decoration demand (OSB, LVL, and reconstituted fancy veneer), and the Chinese government develop policies that favour plantation forestry.
