| 摘 要： | 以油松人工林样地数据为基础,分别建立油松人工林胸径—冠幅模型、胸径生长模型,对黄龙山林区油松人工林进行模拟抚育与预测。结果表明:(1)模拟抚育后,林分平均胸径均有较大幅度增长,种群密度大于4 000株/hm2的样地和2 000~4 000株/hm2的样地抚育后平均胸径相似。(2)种群密度在2 000株/hm2以下的林分在抚育后第6 a可再次进行抚育。(3)种群密度在2 000株/hm2以上的林分在抚育后第9 a可再次进行抚育。

| Abstract: | Based on the sample plots data of Pinus tabulaeformis plantations , we established DBH-crown model and DBH growth model , and performed the simulated tending and predicting the Pinus tabulaeformis plantation in Huanglong Mountain .Af-ter the simulated tending ,the average DBH increased significantly , meanwhile, the average DBH of the >4 000 and 2 000-4 000 ind./hm2 sample plots were similar .Forest stand of population density under 2 000 ind.h/m 2 can be tended again af-ter 6 a.Forest stand of population density more than 2 000 ind./hm2 can be tended again after 9 a. |
