摘　　要：以传统材用竹毛竹为对照,研究了大型丛生竹种车筒竹、箣竹和越南巨竹竹材的物理性质。结果表明,3种丛生竹竹材的基本密度分别为0.606、0.595g·cm-3和0.741g·cm-3,其中车筒竹和箣竹比毛竹材的密度(0.765g·cm-3)小,而越南巨竹与毛竹差异不大;从竹材干缩性来看,车筒竹、箣竹和越南巨竹的气干体积干缩率分别为7.5%、6.9%和6.5%,均比毛竹的相应值要大。3个竹种竹材的物理性能随竹秆部位不同而有差异,从秆基部到梢部,密度呈现逐渐上升的趋势,而干缩性变化规律不明显。Compared with Phyllostachys edulis,a traditional bamboo,the wood physical properties of Bambusa sinospinosa,B.blumeana and Dendrocalamus yunnanicus were studied.The results showed that their basic densities were 0.606 g·cm^-3,0.595 g·cm^-3 and 0.741 g·cm^-3 respectively.Among the densities,D.yunnanicus was parallel to that of P.edulis（0.765 g·cm^-3）,while B.sinospinosa and B.blumeana were slightly smaller.The air-dried volume shrinkage ratio of the three sympodial bamboos were 7.5%,6.9% and 6.5% respectively,which were all higher than that of P.edulis.The physical properties of the three sympodial bamboos had difference in different positions of bamboo culm.From the base to the top,the wood density showed an increasing trend,but the dry shrinkage had no significant variation.
