【Abstract】 The intermediate cutting experiment results of Tongmian Masson pine density experiment forest indicate that the intermediate cutting can evidently promote the DBH growth of different density stands;the periodic increment of the DBH increases with the increase of the intermediate cutting intensity;the influence of the intermediate cutting on the height is not obvious;and both stocking and total stocking reduce with the increase of the intermediate cutting intensity.更多还原
