| 摘 要： | 华北落叶松是华北地区的山地主要树种。通过对开始天然下种后能够良好更新的近熟林分实行大强度抚育,增加了林下光照、并通过清除地被物、开穴播种、补植补造、加强管护等人工促进天然更新措施,形成了林相好,功能强的理想复层林分。缩短了林分的工艺成熟期,提高了商品材经济效益,增加了生物多样性,并节约了抚育和更新造林成本。

| Abstract: | Larix principis-rupprechtii Mayr.is a major tree in North China mountainous region.Understory light is increased by high intensity thinning for near maturity forest beginning naturally seeding.Ideal multi-storied forest with good forest canopy and high function is made by natural regeneration with artificial aid such as wiping off ground cover,sowing after making pits,adding saplings and seeds,strengthening management and protection.The regeneration shorten technical maturity period,increase economic benefits,add species diversity and save costs of thinning and afforesting. |
