摘    要:以河北省木兰林管局北沟林场华北落叶松为研究对象,调查了华北落叶松林下天然更新幼苗的当年生长量。结果表明:①幼苗的生长量随立地条件的变差而变小;②幼苗的生长量随幼苗等级的变化而变化;③幼苗的生长量随林分郁闭度的减小而增大。

关 键 词:环境  立地条件  林分郁闭度  更新

Abstract:Larix principis-rupprechtii updated seedling growth condition of Chengde Beigou Forest Farm of Hebei was investigated as an example. The result showed ① its smaller and smaller seedling growth with the variation of site conditions, ② its seedling growth change with the varyious levels and ③more and more increase of its seedling growth with the de- crease of the stand canopy density.
Keywords:environments  site condition  stand canopy density  update
