摘　　要：以生长在长江滩地、不同倾斜角度的Ⅰ-69杨为实验材料,分析了杨木旋切单板的性质。结果表明:在所选的杨树中,在旋切单板中,从髓心向外方向的起毛率和变形率明显严重。In this paper, 6 trees of poplar 69 （ Populus deltoids CV. I - 69/55 ） with different leaning angle grown in the Is- let beach of Yangtse river was selected as material to analyze the differences of selected wood properties and veneer quali- ties. The results show that the woolly area ratio and the warp ratio of veneer in poplar 69 near bark are severer than that near the pith.
