| 摘 要： | 根据对辽宁山区蒙古栎林下幼树调查资料,采用Simpson指数和Shannon-Wiener指数等进行多样性测度分析,探讨不同间伐强度对蒙古栎林下幼树更新和植物多样性的影响。结果表明:中度间伐强度有利于蒙古栎林下幼树实生更新,从而有利于其诱导成实生林,增强林分抗病虫害能力,提高林下物种多样性,增加林分稳定性。

| Abstract: | In this paper,the regeneration process of young trees and undergrowth biodiversity of Quercus mongolica with different thinning intensity were investigated.The results showed that medium thinning could be beneficial to young trees seedling of undergrowth to regeneration,further which was conducive to induce into the seedling stand,and it also could effectively increase the resistance to diseases and insect pests of forest stand,enhance the species diversity of undergrowth,improve the stability of stand. |
