根据在江西武功山林场定位研究的调查材料,对以残留物管理育林法和以传统育林法所培育的两种杉木林分,在物种多样性以及垂直结构等方面,进行了对比分析。结果表明,残留物管理育林法对杉木林地的物种多样性有着明显有恢复作用。以残留管理育林法所培育的林分,不仅其物种多样性指数已超过江西常绿阔叶林物种多样性指数的下限,而且还具备良好的垂直结构及较高的生境多样性。因此,在我国南方林区,全面推广残留物管理育林法,对这一地区的物种多样性保护以及林业土地资源的持续利用都将具有极其深远的意义。
Based on the investigation materials of the Wugongshan Forest Farm Positioning Study in Jiangxi Province, the comparative analysis was made on the species diversity and vertical structure between the two types of Chinese fir plantations, which were managed by residue management and traditional cultivation. The results showed that the residue management and afforestation method had a significant recovery effect on the species diversity of Chinese fir land. The stand developed by residual management of forest cultivation not only has its species diversity index surpassing the lower limit of species diversity index of evergreen broad-leaved forest in Jiangxi Province, but also has good vertical structure and high habitat diversity. Therefore, it is of far-reaching significance to comprehensively promote residue management and afforestation in the southern part of China’s forests and to protect the species diversity in this region and the sustainable utilization of forestry land resources.
