Abstract: In this study, the disks of Picea brachytyla (Franch.) Pritz. var. complanata (Mast.) Cheng ex Rehd. were chosen as the research object, the morphological characteristics of ring width, tracheid length and width, tracheid thickness of double wall, tracheid lumen diameter, and timber character of wood moisture, dry shrinkage property, and density were measured by the wood anatomic method, in order to study the radial variation law of wood properties. The results showed that Picea brachytyla (Franch.) Pritz. var. complanata (Mast.) Cheng ex Rehd. was a relatively fast-growing tree species with an average ring width of 5.17 mm, and maintained vigorous secondary growth from 1 to 17 years. The tracheid length, width, thickness of double wall and lumen diameter increased gradually from the pith to the outside, which were 1363.98−3498.38 mm, 28.41−43.50 mm, 4.22−6.55 μm, and 13.74−37.20 μm respectively. The water content of air dried wood showed an increasing trend, and the moisture content of raw wood increased slowly at first, and then decreased gradually. There were no obvious variation in shrinkage rate of wood and wood density, showing a stable state on the whole. The results indicated that Picea brachytyla (Franch.) Pritz. var. complanata (Mast.) Cheng ex Rehd. was a relative fast-growing tree species, and the harvest time could was between 17−20 years, which could obtain a relative high timber income.
