| 摘 要： | 通过对梁山慈竹的自然分布格局调查表明,梁山慈竹在川南分布较广,主要的分布形式有3种:零星独丛、数丛小片、集中成片。不同分布形式下,冠蔸面积比差异较大,其中独丛的冠蔸面积比最大。通过回归分析得出胸径和可利用秆重的回归模型为W=0.102029×D2.388139(W:可利用秆重kg,D:胸径cm)。梁山慈竹产量差异较大,通过聚类分析将梁山慈竹产量分为3类:高产、中产、低产。3种不同分布格局产量由大到小分别是数丛小片>成片>零星独丛,产生差异的主要原因是立地条件和林分密度。 |

| Abstract: | The investigations of the Dendrocalamus farinosus distribution have shown that Dendrocalamus farinosus in south Sichuan has a wider distribution,and its main distribution patterns can be divided into three kinds：scattered or individual grove,small pieces of a few groves,and concentrated expanse of groves.Different distribution forms exhibit a greater crown root ball area ratio difference.The individual grove pattern has the maximal crown root ball area ratio.DBH can be gotten by means of regression analysis,and the usable rod weight regression model is W=0.102029 ＊ D2.388139 W means the usable rod weight（kg）,D means diameter（cm）].Dendrocalamus farinosus yield differences are relatively great,and through the cluster analysis,Dendrocalamus farinosus yield can be divided into three categories：high,medium and low yield.The output of three different distribution patterns from large to small is as follows：small pieces of a few grovesconcentrated expanse of grovesscattered or individual grove.The main reasons for the discrepancy are the site condition and stand density. |
