| 摘 要： | 本文根据作者在云南南部筇刺竹集中分布地区所做的调查观测，对筇刺竹的生物学特性，包括形态特征、生态习性、个体结构规律和发笋率与竹丛结构因子的关系进行了分析研究。研究结果表明：筇刺竹是我国南部热区的适生竹种，尤其适于在河谷地带、盆地边缘和低山丘陵地区发展；筇刺竹秆形指标（ｆ１．３）为０．６９５，明显大于其它相近竹种或树木；竹秆最大直径和最长节间出现于秆之中部；胸径与秆高呈指数函数关系，可用Ｈ＝２．２４６４７３Ｄ０．９２６７２５来表达；胸径与秆重呈正线相关，可用Ｗ＝０．１９３３９５（Ｄ２Ｈ）０．６９０４０４来表达；竹丛发笋率、成竹率与秆丛密度和竹丛平均秆径有较密切的关系。本文对竹笋采收指数与老秆采伐年龄的确定进行了探讨

| Abstract: | Bambusa blumeana is a shoot and culm purposed bamboo, which distributed in south China and southeast Asia.The biological and ecological Characteristics of the bamboo, the shoot emergence and development characteristics, the individual structure in variation of size, form weight, wall thickness of the culm, the regression relationship among various construction factor are reported in this paper.On the analysis of the data, structure rule was found in the factors above, some suitable mathematic modelsH=2.246473D0.926725 and W=0.193395(D2H)0.690404]were selected to set up the regression relationship among various construction factors and some tables of investigation planning and measure standard were worked out, so that the natural bamboo forest inventory and management with the standard measurement will be practised on a more reliable and scientific basis. |
