| 摘 要： | 为分析云南香格里拉县高山松天然林林分直径结构特征,用迈耶负指数分布函数、Weibull分布函数、Logistic方程对林分的直径分布进行拟合,对3种分布进行χ2检验,结果表明：用迈耶负指数分布函数描述高山松直径分布效果最好,可用来预测天然高山松林分的直径结构。

| Abstract: | Analysis was made on the diameter structure of Pinus densata natural forest in Shangri-La County,Yunnan Province.The diameter distribution of the forest was drafted with three distribution functions,i.e.,Meyer distribution,Weibull distribution and Logistic distribution,and then Chi square statistics test was applied for the three types of distribution.The results showed that the Meyer negative exponential distribution function fitted the best to express the structure of diameter distribution of P.densata fo... |
