摘 要：
2015年以闽粤栲人工促进天然更新林为研究对象,对其林分结构、林木生长状况、乔木层生物量、地被物生物量、凋落物现存量、土壤理化性质等进行测定,探讨闽粤栲人工促进天然更新林分特征、土壤肥力及生物多样性状况。研究结果表明,与天然林相比,人工促进天然更新的闽粤栲林分生物量增大,林木根系的总量增加,分布空间增大,土壤结构和理化性质得到改良,土壤肥力增大,林内生物多样性得到增强。人工促进天然更新这一措施营林投资成本低,保护生态环境,维护林分较高的生产力,属生态省力可持续经营模式。

摘 要：
In order to study the artificial natural regeneration of Castanopsis fissa stand characteristics and soil fertility,Taking artificial promoted natural regeneration forest of Castanopsis fissa as the research object in 2015,This paper determined the stand structure,forest growth status,tree biomass,ground cover biomass,litter standing stock,soil physical and chemical properties,and discussed artificial promoted natural regeneration forest characteristics of Castanopsis fissa,soil fertility and species diversity. Results showed that compared with natural forest,the stand biomass of artificial promoted natural regeneration forest of Castanopsis fissa was increased and improved,so did the amount of forest tree roots,the space distribution,soil fertility,forest biodiversity,the soil structure and the physical and chemical properties.Artificial promoted natural regeneration forest was a low cost measure,ecological environment friendly,and maintaining higher productivity of stand,also was an ecological energy sustainable business model.
