| 以全国第二次重点保护野生植物资源调查确定的云南分布目的物种作为研究对象进行区系特征分析。结果表明，云南省第二次调查的重点保护野生种子植物共48科94属136种，其中裸子植物5科11属23种，被子植物43科83属113种；在重点保护野生种子植物区〖KG-0.3mm〗系〖KG-0.6mm〗中，属于热带分布类型的最多，有23科49属76种，分别占科、属、种总数的47.92%、52.13%和55.88%，整体呈较强的热带性性质，与云南省生物多样性富集程度高的热带区域相一致；在重点保护野生种子植物只含1种的20科中，东亚特有科水青树科和连香树科均在分类学地位上较为孤立或起源较为古老。 |

| The target species distributed in Yunnan in the second national key protected wild plant resources survey were used as the research object to analyze the flora characteristics. The results showed that the key protected wild seed plants in the second survey of Yunnan consisted of 136 species in 94 genera and 48 families, including 23 species of gymnosperms in 11 genera and 5 families, and 113 species of angiosperms in 83 genera and 43 families; among the key protected wild seed plant flora, tropical distribution had the largest number, with 76 species, 49 genera and 23 families, accounting for 55.88%, 52.13% and 47.92% of the total respectively, showing a strong tropical nature as a whole, which was consistent with the tropical regions with high biodiversity enrichment in Yunnan Province; among the 20 families with only one species of key protected wild seed plants, the East Asian endemic family Tetracentraceae and family Cercidiphyllaceae were relatively isolated in taxonomic status or relatively old in origin. |
