| 摘 要： | 合理确定日本落叶松人工林抚育间伐的间隔期,对经营好森林,促进林木的生长发育作用很大。通过对日本落叶松人工林间伐后,胸径连年生长量下降时间的变化,林分郁闭度需要恢复的时间,自然稀疏率和离散度的逐渐增大的综合分析认为,日本落叶松人工林抚育间伐的间隔时间为5～7年为宜。

| Abstract: | Reasonably determining the thinning interval period of Larix kaempferi were fruitful for managing forests well and promoting growth & development of forest trees.After thinning on Larix kaempferi,through analysis of decreased variation in the time of annual DBH increment,recovery time of canopy density,natural thinning rate & gradual increase of dispersion,result shows that appropriate thinning interval of Larix kaempferi plantation are 5-7 years. |
