| 摘 要： | 利用维泊尔（Weibull)分布函数对山东赤松种群直径的分布规律及其动态进行了初步研究。结果表明，赤松种群直径分布的概率密度分布曲线，由幼龄阶段到成熟阶段，其峰值由左向右移动，由左偏单峰分布过渡为非偏单峰近似正态分布，最后趋于右偏单峰分布，针对不同林型的直径结构，探讨了赤松林的保护和管理。

| Abstract: | By using the Weibull function,the disciplinarian of the diameter distribution and dynamics of Pinus densiflora population in Shandong Province has been preliminarily studied.The results show that from its young period through grown up period,the crest value of diameter distribution of the species move from left to right.Its curve changes from one crest left leaning to one crest no leaning bordering normal school,and eventually to one crest right leaning.According to the structure of the diameter of different types,the measures how to protect and manage Pinus densiflora forests have been discussed. |
