| 摘 要： | 通过对四川盆地区域内的桢楠资源进行调查,其主要以半自然散生状态保存在＂四旁＂和寺庙,成片的人工林相对较少,而且造林成效较差。在自然状态下桢楠林分直径分布规律明显呈正态分布规律,径阶分布离散程度大。在四川盆地发展桢楠人工林时,大面积宜采用桢楠与杉木、马尾松等针叶树种混交方式,＂四旁＂栽植则采用单行或双行造林模式。 |
| 关 键 词： | 桢楠 生长 径级分布 |

| Abstract: | Based on the investigation of Phoebe zhennan resources in the Sichuan Basin region,they were mainly conserved in semi-nature conditions,scattering on ＂four-side＂ or in temples,large-scale planttations were relatively less,and their afforestation effect was poor.The diameter distribution regularity of Phoebe zhennan trees under natural condition displayed a normal distribution,and the distribution of their diameter grade had a high discrete degree.When planted in a large area,Phoebe zhennan and Chinese fir or Phoebe zhennan and Masson pine should be used in the Sichuan Basin region,and planting on ＂four-side＂ should adopt single line or double line modes. |
