摘　　要：报道了 18年生枫杨树高、胸径和材积生长规律以及纤维形态、基本密度和化学成分含量的径向、纵向变异模式 ,这些性状变化规律与有关理论是一致的。枫杨木材幼龄期为 8～ 9年。从造纸原料要求评价 ,枫杨纤维长度属于中等 ,壁薄、腔大、长宽比适中 ,木材密度值稍微偏低 ,木材化学成分含量适中 ,是适合的造纸原料。枫杨林木改良可重点提高木材密度。The growth patterns of tree height, DBH and volume for Chinese wingnut and the variation patterns of wood fibre dimension, basic density and chemical components are expounded. These variation patterns are identical to some theories in wood science. Its wood juvenile period is about 8～9 years old. Owing to its wood with characteristics of medium fiber length, thinner fiber wall, larger fiber diameter, larger ratio of fiber length to width and higher chemical contents in cellulose and lower in lignin, its plantation resource is suitable for pulp and paper. Aiming at the lower wood density, it should be improved through tree breeding.
