By using the Weibull distribution density function,the law of diameter distribution of the Pinus tabulaeformis plantation forest in North China was fitted and tested and whose diameter distribution character was analyzed.
本文利用Weibull分布密度函数对华北地区油松人工林直径分布规律进行了拟合检验与直径分布特征分析,结果表明:(1)整个调查地区油松人工林的直径分布不太合理,林分的密度需进行必要的调整,尤其是对于高密度造林的地段;(2)整个调查地区绝大多数林木的直径分布仍表现为中度偏小的径阶林木株数占多数的特点,急需进行必要的抚育间伐,以提高油松人工林质量;(3)平均胸径与Weibull分布密度函数三参线性回归分析的结果还不能充分应用于生产实践,有待于今后深入的探讨与试验。
