摘要
分析了油松人工林高强度疏伐后,在不同管理密度条件下,林分生长、材积生产量和价值收益的差异。提出了对人工林实行低密度管理(高强度、低频度间伐)的改进意见。
Describes the stand and volume growth as well as the income value of Chinese pine (Pinus tabulaeformis Carr. ) Plantations under different managed stand densities as effected by various thinning intensities. It was suggested that a low stand density management and a proper heavy thinning with low thinning frequency will be adequate.
