摘　　要：对进口阔叶木材南洋楹和石梓的化学成分、材性特点、纤维形态及制浆性能进行了研究。结果表明,南洋楹的灰分、冷热水抽出物和苯-醇抽出物含量低于石梓,Klason木素和纤维素含量两者相当,但是南洋楹的1%NaOH抽出物和戊聚糖含量明显高于石梓。南洋楹的纤维平均长度为1.08 mm、石梓的为1.15 mm。采用硫酸盐法制浆,打浆后南洋楹与石梓浆的裂断长分别为11.9 km和11.5 km;撕裂指数分别为5.12 mN.m2/g和6.56 mN.m2/g。The fiber morphology and pulping and papermaking feasibility of Albiziafalcataria and Gmelina arborea were investigated in the paper, also their main chemical compositions were determined. The results showed that the ash content and the contents of cold water and hot water and benzyt ethanol extractives of Albiziafalcataria are lower than that of Gmelina arborea, the contents of lignin and cellulose of Albiziafalcataria is similar to that of Gmelina arborea. On the other hand, the contents of I%NaOH extractive and hemicetlulose of Albiziafalcataria are higher than that of Gmelina arborea.The fiber average length of Albiziafalcataria is 1.08mm and similar to 1.15mm of Gmelina arborea. After beating, the breaking lengths are 11.9km and 11.5km, and the tear indexes are 5.12mN-m^2/g and 6.56 mN·m^2/g for the kraft pulps of Albiziafalcataria and Gmelina arborea respectively.
