摘要: 以汪清林业局的20块人工落叶松为例,对间伐林分的断面积和蓄积进行生长趋势分析,用普雷斯勒公式计算林分的平均生长率,分析不同间伐强度对林分断面积和蓄积的影响,结果表明:间伐林分在间伐初期的断面积和蓄积小于未间伐林分,但随着林龄的增大,间伐林分断面积和蓄积向未间伐林分渐近;间伐强度越大,年平均生长率越大;方差分析表明,不同的间伐强度对林分断面积和蓄积生长的影响差异显著。

关键词: 间伐, 断面积, 蓄积, 落叶松

Abstract: With Larix olgensis plantation of the WangQing ForestBureau as an example, the paper studied the growth trend of the basal area and volume, calculated the average growth rate of the plantation by pressler formula,analyzed the effects of thinning on the basal area and volume. The result shows that in initial stages the basal area and volume of thinned plots is less than those under control, but the basal area and volume of thinned plots graduallyapproached to those under control with the increase of age; the growth rate willincrease with the increase of thinning intensity; the analysis of variance indicated the effects of thinning intensity on the basal area and volume is prominent.

Key words: thinning, the basal area, volume, Larix olgensis
