中文摘要：

种类丰富，种类差异和种类平均的五个索引被用来估计经历的具球果的森林的多种四种类型不同人工的新生时间。学习基于森林的垂直结构，包含 growth-formsof 总数植物以及木质的植物的垂直的层。结果证明除了木质的植物的第四层，四个森林的垂直结构以他们的种类丰富，种类差异和种类平均展出了重要差别，建议一个种类差异索引提供了更多详细说明了信息并且是在这个区域反映新生过程的一个更好的索引。silvicultural managementofartificially 改革了森林，这被推荐应该被加强保存森林的生物多样性，优化森林结构并且长远来说，支持森林生态系统的持续开发。

英文摘要：

Five indices of species richness, species diversity and species evenness were used to assess a diversity of four types of coniferous forests undergone different artificial regeneration time. The study was based on the vertical structure of forests, involving growth-forms of total plants as well as vertical layers of woody plants. The results showed that, except for the fourth layer of woody plants, the vertical structure of the four forests exhibited significant difference in terms of their species richness, species diversity and species evenness, suggesting that a species diversity index provided more detailed information and was a better index reflecting the regeneration processes in this region. It was recommended that silvicultural management of artificially regenerated forests should be strengthened to conserve the biodiversity of the forests, optimize forest structure and, in the long run, promote sustainable development of forest ecosystems.
