| 摘要: |
| 在广东省乳阳林场郁闭度 0~0.6 的杉木林 Cunninghamia lanceolata 内开展补植套种枫香
Liquidambar formosana 的试验。方差分析结果表明，不同郁闭度下补植套种枫香，其树高、地径及材积
增长差异显著（a=0.05）; 郁闭度 0~0.6 内，郁闭度越低，枫香幼林生长越好，在郁闭度 0.4 以上的林地补
植套种时，枫香的树高、地径、材积等生长明显受到抑制，因此，补植套种枫香应选择在郁闭度 0.4 以下
的林地上进行。 |

| Abstract: |
| The experiments on interplanting Liquidambar formosana in Cunninghamia lanceolata with
canopy density of 0-0.6 in Ruyang forest farm of Guangdong province.The results of the variance analysis showed
that there are significant differences on tree height，ground diameter and volume of wood for canopy density
（a=0.05）. The lower of canopy density, the better the growth of L. formosana with 0-0.6 of canopy density.
It restrained the tree height ,ground diameter and volume on 0.4 of the canopy density.So, it must choosed the
forestry with canopy density under 0.4 to interplanting L. formosana. |
