摘    要:利用帽儿山地区的红松、长白落叶松人工森临时样地资料,系统分析了影响人工林天然更新的干扰因素;林分密度、林缘效应、种源、立地、林地形状与面积大小等。干扰的结果往往对林分更新产生正效应或负效应。研究表明,林分密度负效应,林缘产生正效应,以120m作为种源干扰的有效距离指标,人工造林面积应控制在4hm^2左右比较适宜。

关 键 词:人工林  天然更新  干扰效应  人工干扰方式

Disturbing Effects and Artificial Disturbing Method during the Process of Natural Regeneration of Artificial Forest
WANG Chengyi.Disturbing Effects and Artificial Disturbing Method during the Process of Natural Regeneration of Artificial Forest[J].Forestry Science & Technology,2000,25(5):1-3.
Authors:WANG Chengyi
Abstract:In this paper,the disturbing factors included stand density,border effect,provenance,site,the shape and size of site which effected on the natural regeneration were analyzed systematically. The disturbing may have positive or negative effects on the natural regeneration,for the investigation area,stand density has a negative effect;forest border has a positive one;and the results show that the artificial planting area should be limited to 4hm 2,if the effective distance of provenance disturbing was chosen 120m.
Keywords:Artificial forest  Natural regeneration  Disturbing
