摘　　要：对东京野茉莉木材纤维形态特征及主要化学成分进行了分析，结果表明，木材纤维长度为1317-1657μm，长宽比为43．94—56．78，壁腔比为0．32—0．53，基本密度为0．3739g／cm^3，综纤维素含量为78．618％，α-纤维素含量为41．694％，10g／L氢氧化钠抽出物为25．328％，木质素为20．314％。通过初步分析发现，东京野茉莉是亚热带超短轮伐期纸浆材的较理想树种，有较高的开发利用价值。The fiber morphology features and chemical composition of Styrax tonkinensis were studied, the result showed that the fiber length changed from 1 317 to 1 657μm,the ratio of fiber length to width was 50.92%, the ratio of wall thickness to lumen was 0.411 081, the basic density was 0.373 86 g/cm^3. The content of holocellulose of the wood was 78.618 %, the content of a - cellulose was 41. 694%, the content of 10 g/ L NaOH extractive was 25. 328% ,the content of lignin was 20. 314%. Styrax tonkinensis is a plant which is suitable for pulpwood in subtropical areas, being of potential value for exploitation and utilization.
