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，林分郁闲度需要恢复的时间，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。

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.
