摘　　要：采用5种木材腐朽菌,分别对30株天然林白桦木材进行木材腐朽处理,检测并比较腐朽木材和新鲜木材中木质素、纤维素等主要化学成分的变化。结果表明,木蹄层孔菌腐朽后的白桦木材其重量、木质素和纤维素损失率最高,桦剥管菌次之,白囊耙齿菌最低;木蹄层孔菌腐朽后的白桦木材纤维素含量略高于新鲜白桦木材,其他4种菌腐朽后的白桦木材纤维素含量都低于新鲜白桦木材,其中桦剥管菌和彩绒革盖菌腐朽后的白桦木材纤维素含量较低。木蹄层孔菌腐朽后的白桦木材1%NaOH抽出物含量最低,苯醇抽出物含量中等,纤维素含量最高,木质素含量较低,相比之下它腐朽白桦木材的能力较强,适用于以白桦木材为原料的生物辅助造纸。5 wood rot fungus were used to make decaying treatment to 30 wood samples of white birch, in which the wood chemical component including lignin and cellulose was measured and compared between rotted wood and fresh wood samples. The result showed that the wood mass, lignin and cellulose loss rate of the wood decayed by Fomes fomentarius was in the highest, Piptoporus betulinu.s was in the second, and Irpex lacteus was in the lowest. The cellulose content of the rotted wood by Fomes fomentarius was higher than that of the fresh wood. The opposite results were obtained by the other four fungus, in which the cellulose content of Piptoporus betulirms and Coriolus versicolor was in the lower level. The wood decayed by Fomes fomenmrius had the lowest 1% NaOH extraction, middle level benzene -alcohol extraction, and the highest cellulose content, as well as lower lignin content which showed better decaying ability to the wood of white birch, and was more appropriate for boilogieal assistant pulp - making.
