摘　　要：以大白藤和小白藤为研究对象,统计分析了2种藤材纤维径向变异特性,并研究了其主要物理力学性质,为其加工利用提供参考。结果表明,纤维形态在由藤皮到藤芯方向上,大白藤和小白藤的纤维长度均逐渐下降,分别为1885.78μm和1528.94μm。小白藤纤维长宽比>90,壁腔比<1.3,比较适宜作为造纸原料。与小白藤相比,大白藤具有较高的密度和较低的干缩性。两者均有着较好的抗弯性能,且大白藤抗压性能优异。Rattan canes of Calamus faberii and C.balansaeanus were chosen as experimental materials,the fiber characteristics of them in radial directions were counted and analyzed,and the main physico-mechanical properties of the rattan canes were studied in order to provide references for the cane processing and utilization .The results showed that the fiber length of C.faberii and C.balansaeanus were 1 885.78 and 1 528.94 μm,respectively.Both of them declined gradually from outside to inside in radial direction.The length-width ratio of C.balansaeanus was over 90,and the cell wall-lumen ratio was below 1.3,so C.balansaeanus cane was suitable for papermaking raw material.Compared with C.balansaeanus,C.faberii had a higher density and lower shrinkage.Both had good flexural behavior,and C.faberii had excellent compressive properties.
