摘要:毛花酸竹(Acidosasa hirtiflora)是一个具有很高开发价值的优良大中型笋、材两用散生竹种,在云南东南部有大面积的天然竹林分布。本文首次对滇东南屏边县分布的典型毛花酸竹天然竹林进行了个体结构特征调查,对随机选择的128株标准竹解剖测量后,拟合了秆重(W)、秆高(H)、胸径(D)、壁厚(T)等秆形指标之间的回归关系式,其中秆重与秆高、胸径之间存在极显著相关关系,回归方程式为W=0.095D1.449H0.834(r=0.996),并以此回归模型构建了毛花酸竹基于秆高和胸径的二元重量表。本文对于全面了解毛花酸竹的个体结构规律有着重要意义,并可为毛花酸竹天然林资源的合理经营和大径级竹秆材培育技术的研制提供基础资料。
Acidosasa hirtiflora(Hsueh et Yi) Keng f.is an excellent medium-to large-sized running bamboo with high economic value,and there are sizeable areas of natural stands of this bamboo in southeastern Yunnan.This paper presented the first report on the individual culm form structures of A.hirtiflora in Pingbian County of southeastern Yunnan.Based on data of randomly selected 128 standard bamboo culms,regression equations were calculated out among the culm weight(W,Kg),culm height(H,m),culm diameter at breast height(D,cm) and culm thickness(T,cm).Significant correlation relationship was found among W,H and D which could be expressed as regression equation W = 0.095D^1.449H^0.834(r = 0.996).Meanwhile,binary form of culm weight was constructed based on above regression equation.This study was of great significance for comprehensive understanding of individual structure features of A.hirtiflora,and provided basic data for cultivation of the large-diametered bamboo timber and management of natural A.hirtiflora forest.
