摘要: 山西有木本植物463种,隶属于166属70科,种属的区系地理成分类型多样,以北温带成分占优势,它们是构成山西植被的主要建群种或优势种。对山西及邻近地区植物区系地理成分的多样性指数、PCA排序和类平均聚类的结果表明:山西与河北、北京、山东等省市木本植物区系地理成分较为相似,而与河南、江西、内蒙古3省区有较大的异质性.

Abstract: There are 463 species of xylophyta, belonging to 166 genera and 70 families in Shanxi, China. The floristic geographic composition types of the genera and the species are abundant, in which the temperate compositions (including North Temperate, Old World Temperate, Temperate Asia & Central Asia) are dominant, they are constructive or dominant species of vegetation in Shanxi. Moreover, the floristic geographic compositions of xylophyta of Shanxi, Hebei, Beijing, Shandong, Henan, Jiangxi and Inner Mongolia were studied by using diversity index, principal component analysis and group average method, respectively, and the results indicated that the floristic geographic composition of Shanxi was considerablly similar to that of Hebei, Beijing and Shandong, however, the floristic of Shanxi was comparatively different from that of Henan, Jiangxi and Inner Mongolia.
