| 摘 要： | 应用多样性分析方法和改进后的 M.Godron 稳定性测定方法研究常绿阔叶林5种不同强度采伐(弱度9.8%、中度24.5%,强度46.8%和极强度72.3%和皆伐)作业10 a后林分结构稳定性.结果表明,择伐林地林分处于稳定状态,随着择伐强度的增强,林分的稳定性开始逐渐降低.皆伐林地林分处于不稳定状态.对于常绿阔叶林的科学经营,从稳定性出发,应尽量采取择伐方式,尤其是中低强度的择伐方式.

| Abstract: | Analysis of the evergreen broad-leaved Forest stand structural stability after the 5 kind of types of cutting intensity operation(low intensity,9.8%;middle intensity,24.5%;high intensity,46.8%;over-high intensity,72.3%)with Diversity method and the improved expression of the M.Godron stability measurement method.The result showed that the selective cutting is benefit to stability of stand structures,With selective cutting intensity enhancement of the stability of the stand began to decrease.Clearcutting woodlands stand in an unstable state.From the stability of the scientific management of the evergreen broad-leaved forest,selective cutting should be taken,especially in low-intensity selective cutting. |
