| 摘 要： | 通过对桉树速生林基地的生态调查及监测，分析得出以前我国桉树速生林普遍存在地力衰退的问题，导致土壤肥力下降及目前桉树人工林地力衰退已经得到根本性的逆转的主要原因。速生林基地种植的桉树林林下植被与林缘、林外植被没有显著不同，特别是与桉树林地块相近的稀疏马尾松林林下植被以及荒坡植被相比，无论从植被覆盖度、植物种类、高度等看都呈现出增高、增多的趋势，而广东雨量丰富，桉树能同绝大部分林下植物共生。

| Abstract: | Soil fertility declines were common problems in Eucalyptus fast-growing forest of China.Based on ecological investigation and monitoring of eucalyptus fast-growing plantation,the analysis is carried out and main reason of soil fertility decline and fundamental reversal in current recession were concluded.There were no remarkable differences between undergrowth inside and outside or forest-fringed Eucalyptus forest in Eucalyptus fast-growing plantation.Particularly,the indices such as vegetation coverage,pla... |
