贵州自然分布的古树名木有161种,隶属于52科100属。其中蕨类植物1科1属1种;裸子植物8科18属29种;被子植物43科81属131种。在对这100属的植物地理区系分析后得知:1.世界分布1属;2.泛热带分布及其变型14属;3.热带亚洲和热带非洲间断分布3属;4.旧世界热带分布2属;5.热带亚洲至热带大洋州分布4属;6.热带亚洲至热带非洲分布1属;7.热带亚洲分布及其变型13属;8.北温带分布及其变型19属;9.东亚和北美间断分布14属;10.旧世界温带分布及其变型3属;11.温带亚洲分布为0;12.地中海区、西亚至中亚分布及其变型1属;13.中亚分布及其变型为0;14.东亚分布及其变型10属;15.中国特有分布15属。对贵州自然分布的161种的地理分析得知:热带亚洲分布12种,热带亚洲—热带大洋州2种,北温带分布1种,地中海区至温带、热带亚洲1种,东亚分布23种,我国特有分布的有122种,其中4种为贵州特有。
ABSTRACT There are 161 species, 100 genera, and 52 families of ancient and famous plants in Guizhou, Among them, 43 families are Angiospermae belonging to 81 genera or 131 species, 8 families of Gymnospermae belonging to 18 genera or 29 species, and 1 families are Pteridophy belonging to 1 genus or 1 species. According to the analyzing of the districts of the 100 genera plants, we can infer as follow：l, 1 genus is Cosmopolitan;2.14 genera are Tropicopolitan or aberrant ;3. 3 genera are tropical Asian and tropical African disjuncted ;4. 2 genera are Palaeotropical;5. 4 genera are tropical Asian and tropical Australian;6, 1 genus is tropical Asian and tropical African;7, 13 genera are tropical Asian or aberrant;8 . 19 genera are the North temperate elements or aberrants;9, 14 genera are East Asian and North Amer. disjuncted; 10. 3 genera are Palaeotemperate or aberrants;ll, 0 genus is temperate Asian;12. 1 genus is Mediterranean,Western Asian and Middle Asian or aberrants;13. 0 genus is Middle Asian or aberrants;14. 10 genera are East Asian or aberrants;15. 15 genera are Endemic to China. According to the analyzing about the district of the 161 species plants, we can infer as follow： 1、12 species are tropical Asian ;2、 2 species are tropical Asian and tropical Australian ;3、 1 specie is the North temperate element; 4、1 specie is the element from Mediterranean to temperate and tropical Asian ;5、23 species are East Asian. Among them, 122 species are the endemic plant species of China and 4 species are the endemic plant species of Guizhou.
