| 摘 要： | 运用系统结构决定功能的原理,以培育健康稳定的森林为目标,从林分的空间结构和非空间结构特征2个方面选择了8个指标,提出了林分经营的迫切性指数(Mu)的概念、评价方法及评价标准,并应用于贵州黎平2个阔叶混交林和2个针阔混交林分的评价,结果表明:4个林分的经营迫切性不同,2008年初的低温雨雪冰冻灾害对4个研究林分(样地A、B、C和D)的林木个体破坏严重,常绿阔叶混交林(样地A和B)的树种组成、针阔混交林(样地C和D)的林木分布格局、成层性以及直径分布等不合理;此外,样地B的树种多样性和样地C的顶极树种优势度较低,4个林分都需要从提高林木个体的健康水平制定相应的经营措施,常绿阔叶混交林还需要调整树种组成,提高树种多样性;针阔混交林则还需要调整林木分布格局、直径分布及成层性,优化空间配置.

| Abstract: | Based on the basic principle of The structure of systems determines its function and taking stable and health forest as management goal,the paper put forward stand management urgency evaluation index(Mu)and its evaluation method and standard based on 8 stand structure indicators.The evaluation method was applied in 2 broadleaved mixed forest(stand A and B) and 2 mixed forest(stand C and D) in Liping,Guizhou province,the resulted show that the management urgency of 4 stands was different.The low temperatur... |
