摘  要：
对柞蚕场、柞蚕场封山育林6a、9a的植被调查数据进行了分析,结果表明:柞蚕场封山育林可明显促进蒙古栎等乔木的生长和郁闭,但由于萌生,林木的水平分布多呈现聚集于母树的丛状分布;封育后由于林分郁闭,林内光照降低,灌木和草本植物的盖度有所减少;通过多样性指数测度,封育后乔木层、灌木层、草本层的多样性指数均高于柞蚕场;封育后由于森林凋落物的增加使枯落物存储量不断增加,可改善土壤肥力、提高林地涵养水分的功能。

摘  要：
Analysis on vegetation data regarding tussah forests and closing of tussah forests for 6 and 9 years were conducted.The results indicated that closing of tussah forests could promote such trees' growth and closure as Quercus mongolica,but the horizontal distribution of young trees mostly showed a plexiform pattern by gathering around the seed trees owing to sprouting.The coverage of shrubs and herbs decreased as light decreased after tussah forests were closed.The diversity index of trees,shrubs and herbs were all higher in closed tussah forests than that in tussah forests.Litter storage in closed tussah forests increased year by year,which would improve soil fertility and enhance the function for water conservation in forest lands as well.
