摘　　要：采用显微图像分析方法,对龙竹主要解剖特征进行了研究,为提高建筑用丛生竹资源高附加值加工利用水平提供理论。结果发现,龙竹薄壁细胞、纤维、导管和筛管比量分别为60.9%、34.6%、4.0%和2.1%。纤维直径、双壁厚、腔径和长度分别为19.043、9.518、9.525和2 546.235μm,纤维长宽比、壁腔比和腔径比分别为134.053、1.214和0.487。维管束径向直径和弦向直径分别为862.803和702.743μm,维管束密度为1.133个.mm-2。In order to improve the levels of high value-added processing and utilizing for sympodial bamboo, the main anatomical characteristics of D. giganteus have been studied with the microscopic image analysis method. The results are as follows： the proportion of parenchyma, fiber, vessel and sieve tube are 60.9%, 34.6%, 4.0% and 2.1%, respectively. The average values of fiber width, double-wall thickness, lumen diameter, length, length-width ratio, double-wall thickness-lumen diameter ratio and lumen diameter-width ratio are 19.043 pro, 9.518 um, 9.525 um, 2 546.235 um, 134.053, 1.214 and 0.487, respectively. The radial width, tangential width and frequency of vascular bundle are 862.803 um, 702.743 um, and 1.133 individual.mm-2, respectively.
