| 摘 要： | 人工促进天然更新是恢复和发展天然阔叶林的重要更新方式,具有投入少、恢复快、收益大和易于实施等特点.人工促进天然更新的阔叶次生林与人工营造杉木林样地比较结果表明,在同一立地条件下,同龄阔叶树的树种种类、郁闭度、生物多样性、高径比等各项生长指标均高于人工杉木林.文中阐述了人工促进天然更新中的抚育间伐、林分改造、封山育林和封禁保护、补植等具体措施,并提出保护现有阔叶林,实施人工促进阔叶林天然更新,扩大水源涵养林、水土保持林等防护林比重等建议.

| Abstract: | With small investment,quick recovery,more benefit and easy operation,artificial promoting natural regeneration is an important updated way for restoration and development of natural broadleaf forest.Comparing sampling sites between broadleaf secondary forest of artificial promoting natural regeneration and artificial fir afforestation,the results showed at the same site conditions,canopy density,biodiversity,high ratio and other growth indicators of same age broadleaf species type are higher than the artificial fir.The thinning technology,forest stand transformation,fenced off for afforestation and enclosure conservation,replanting and other specific measures of artificial promotion natural regeneration,have been described in this paper.It is also proposed to protect the existing broadleaf forest,broad-leaved forest of artificial promoting natural regeneration,expand water conservation forest,soil conservation forests,etc. |
