摘  要:
以10a生日本落叶松人工林为材料,分别进行15%,25%,40%不同间伐强度试验,抚育间伐6年后,调查林木胸径与树高,分析表明强度抚育间伐对胸径影响与不抚育、弱间伐强度相比差异极显著;中度间伐与不抚育差异显著。不同抚育间伐强度对高生长量、单位面积林分蓄积影响差异不显著。

摘  要:
We adopted three different(including 15 percent,25 percent and 40 percent)thinning intensity experiments on the 10-year-old Larix kaempferi plantation.After six years of tending and thinning,DBH and tree height were investigated.The experimental results indicated that the heavy cutting's effect on DBH were extremely significantly different with no cutting or light intermediate cuttings,and there were significantly different with moderate cuttings and no cuttings.Different intensity of intermediate cuttings has no significant difference on high growth and stand volume per unit area.
