摘　　要：以《国家重点保护野生植物名录》为基础,对云南省分布的国家重点保护野生种子植物资源的区系特征进行分析。结果表明:云南省分布的国家重点保护野生种子植物共81科167属482种,其中裸子植物6科14属44种,被子植物75科153属438种;在重点保护野生种子植物区系中,以热带分布科数量最多,有37科97属306种,分别占各总数的45.68%、58.08%、63.49%,整体呈现出较强的热带性质,与云南省生物多样性富集程度高的热带区域相一致;在云南分布国家重点保护野生种子植物38个单种科中,东亚特有科的水青树科、连香树科,均在分类学地位上较为孤立或起源上较为古老。Based on the List of National Key Protected Wild Plants,the floristic characteristics of the national key protected wild seed plant resources distributed in Yunnan Province were analyzed.The results showed that there were 482 species of wild seed plants under national key protection in Yunnan Province,including 81 families,167 genera,44 species of gymnosperms in 6 families,14 genera,and 438 species of angiosperms in 75 families,153 genera;among the key protected wild seed plant flora,the number of tropical distribution families is the largest,with 306 species belonging to 97 genera and 37 families,accounting for 45.68%,58.08%and 63.49%of the total,respectively,showing a strong tropical nature as a whole,consistent with the tropical region with high biodiversity enrichment in Yunnan Province;among the 38 single-species families of national key protected wild seed plants distributed in Yunnan,the family of Cymbiceae and the family of Pistaceae,which are endemic to East Asia,are both relatively isolated in taxonomic status or ancient in origin.
