摘　　要：梁山慈竹分布于西南各省,广泛用于造纸、人造板及园林绿化等。以梁山慈竹为研究对象,测定不同年龄,不同径级的标准竹,对其胸径、竹高、秆高、节长、节数、竹壁厚、基部直径、各构件单位的生物量等因子进行统计分析,研究梁山慈竹秆形结构和地上部分生物量结构。结果发现胸径与地上部分鲜重、秆重、秆高等因子拟合较好;梁山慈竹的竹节长度呈"短-长-短"的分布规律;梁山慈竹的地上部分生物量为104 t/hm2。Dendrocalamus farinosus is distributed in the southwestern areas of China and widely used in papermaking, woodbased panel and landscape etc. The DBH, culm height, internodal length, wall thickness, diameter at base and the biomass of module units of the standard bamboos with the different ages （or diameter classes） were measured to study the structure of culm form and the structure of biomass of D. farinosus in this paper. The results showed that the DBH of D. farinosus was closely related to the fresh biomass aboveground, the eulm weight and the culm height. The bamboo node length of D. farinosus was showed as ＂short→long-→short＂ with the ages. The biomass aboveground of D. farinosus was 104 t/hm2.
