摘要: 我们基于对油松天然林54个林分针叶,球果和种子三方面18个形态特征的测定,借助于多变量分析技术,研究了油松种群的地理分化问题。结果表明,基于相关系数进行的聚类分析和主分量分析,得到的结果比较接近。据此,将油松划分为西北群、乌拉山群、西南群、南部群、中部群、山东群、东北群、东部群、山海关群,供进一步种源研究的基础。

Abstract: The geographical differentiation of Pinus tabulaeformis Carr. Is discussed and illustrated by means of multivariate analysis with data from 18 morphological traits of needle, cone and seed in 54 natural forest stands. According to the results obtained from cluster analysis and principal component analysis, nine local populations are classified.
