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
