辽东栎次生林人工促进天然更新措施研究

Study on Artificial Measures to Promote Natural Regeneration in Secondary Forest of Quercus Liaotungensis

在山西省太岳山地区,选择10个具有代表性的辽东栎次生林,研究不同人工促进天然更新措施对辽东栎幼苗更新的影响。结果表明,清理地表枯落物并刈割地表草本且采取水平阶整地的样地辽东栎幼苗出苗量与保存量明显高于其他处理,其次为清理地表枯落物且采取水平阶整地处理。采取人工促进天然更新措施后,不同林分密度和海拔条件下辽东栎幼苗的出苗量与保存量均无显著差异。综上所述,适宜的人工促进天然更新措施对辽东栎次生林下的幼苗更新促进作用明显,可为辽东栎次生林可持续生长和正向演替提供有利条件。

In the Taiyue Mountain area of Shanxi Province,10 representative secondary forests of Quercus liaotungensis were selected to study the effects of different artificial measures to promote natural regeneration on the regeneration of Quercus liaotungensis seedlings.The results showed that the seedling emergence and preservation of Quercus liaotungensis seedlings were significantly higher in the sample plots which clearing all litter,cutting surface herbs and adopting horizontal leveling treatment,followed by clearing all litter and adopting horizontal leveling treatment.After adopting artificial measures to promote natural regeneration,there was no significant difference in the emergence and preservation of Quercus liaotungensis seedlings under different forest densities and altitude conditions.In summary,appropriate artificial measures to promote natural regeneration had a significant promoting effect on seedling regeneration in the secondary forest of Quercus liaotungensis,which could provide favorable conditions for sustainable growth and positive succession of Quercus liaotungensis secondary forest.
