摘　　要：初植密度对落叶松人工林的纤维形态特征、物理特征及化学特征有重要的影响 ,除生长轮宽度外 ,其它各指标差异显著 ;初植密度为 2 .0m× 2 .0m的林分纸浆材材质相对最好 ;采用综合坐标法对不同初植密度的林分进行纸浆材材质评定的优劣顺序为 2 .0m× 2 .0m、2 .5m× 2 .5m、1.5m× 2 .0m、3.0m× 3.0m。Planting density has significant effects on fiber morphology, physical and chemical properties of Lalix olgensis wood. Except growth-ring width, remarkable differences was found in other indexes. The wood quality for planting density 2.0 m×2.0 m was the best in chemical pulp features. By comprehensive coordinates, the pulpwood qualities for different planting density were evaluated, and the preferential order were 2.0 m×2.0 m, 2.5 m×2.5 m, 1.5 m×2.0 m and 3.0 m×3.0 m.
