摘　　要：以云南省第四次森林资源规划设计调查中云南松天然林地的小班数据资料为研究对象,统计分析各小班优势木平均树高与年龄的关系,确定云南松天然林的基准年为26 a,以log-modified函数拟合树高生长导向曲线,编制峨山县云南松天然林地位指数表。采用卡方检验和落点检验,检验结果表明,其树高理论值与实际值无显著差异。该表可作为评定峨山县天然云南松林分质量及立地质量优劣的依据。Based on the subcompartment data of Pinus yunnanensis natural forest in the fourth forest inventory planning and design in Yunnan Province,the relationship between the average tree height and the age of dominant trees was analyzed,and the base year of Pinus yunnanensis natural forest was determined to be 26 years.The log-modified function was used to fit the growth guide curve of tree height,and the site index table of Pinus yunnanensis natural forest in Eshan County was compiled.The results of chi-square test and falling point test showed that there was no significant difference between the theoretical and actual tree height values.The table could be used as a basis for evaluating stand quality and site quality of Pinus yunnanensis natural forest in Eshan County.
