| 摘 要： | 以云南松林近自然化采伐样地的调查资料为依据,分析了改造措施对云南松群落特征的影响。结果表明,通过近自然化采伐降低了云南松在林冠层的地位和作用而提高了阔叶树在林冠层的地位和作用,并使云南松种群的树干通直度结构得到明显改善,更新层和草本层物种多样性也显著提高。而且,近自然化采伐在经济上具有可行性。

| Abstract: | Based on the plot data of near-nature cutting,effects of restructuring measures on Pinus yunnanensis forest communities were analyzed.The results showed that the status and function of the pine canopy were reduced whereas canopy functions of broad-leaved trees were increased,and that the straightness of the pine and the plant diversity in regenerations and herbaceous were improved as well through near-nature cutting.Near-nature cutting was proven to be economically feasible. |
