| 摘 要： | 本文采用系统聚类分析方法对中国黄杨属植物20种、3亚种和2变种进行了分类学研究，研究结果表明：营养器官的32个特征性状、繁殖器官的35个特征性状和总的67个特征性状的系统聚类结果与该属植物形态分类结果相吻合，从而为该属植物新分类群的建立，种、亚种和变种的鉴定以及某些划分不合理的种群纠正提供了一种新的科学依据和手段。

| Abstract: | A quantitative classification study on the 20 species,3 subspecies and 2 varieties of Buxus L. from china was carried out by meas of system cluster method. The results showed that: the cluster results of 2 characters of nutrition organs. 35 characters of reproduction organs and total 67 charaters were identical with the morphological classification.Therefore we provide an independent method and scientific basis for establishing and determining of new groups,species,subspecies and varities of Buxus L. |
