| 摘 要： | 通过对石漠化地区8 a生芳樟(Cinnamomum camphora)人工林测定分析,结果表明:芳樟的树高、胸径及材积生长规律均呈现出前期缓慢、后期快速的特性,造林第4年后胸径生长进入速生期,第5年后树高快速生长,材积生长的速生期则出现在第6年;估算芳樟单位面积纤维材产量达24.32 t/hm2,芳樟油95.67 kg/hm2,单位面积产值达18080元/hm2;枯落物蓄积量为5.57 t/hm2,有效拦蓄量达6.36 t/hm2,高于相同立地的任豆(Zenia insignis)和苏木(Caesalpinia sappan).

| Abstract: | The 8-year-old Cinnamomum camphora plantation in karst desertification area was measured and analyzed. The results showed that the tree height, diameter at breast height (DBH) and volume growth regularity of C. camphora showed a trend of early slow development and later rapid growth. The fast-growing period began on the fourth year, the fifth year and the sixth year in DBH, tree height and volume growth respectively. The fibre timber yield was 24.32 t/hm2; aromatic camphor oil yield was 95.67 kg/hm2; the output value was ￥18080 per hectare; forest litter amounts was 5.57 t/hm2; and the effective retaining contents was 6.36 t/hm2, which was higher than the Zenia insignis and Caesalpinia sappan. |
