| 摘要: |
| 经野外调查和资料整理，贵州省黎平县太平山自然保护区共有野生种子植物147科492属1 178种（含种下等级）。区系成分分析表明：在科级水平上，热带分布科占保护区非世界分布科的65.25%，温带分布科占34.75%，热带成分明显占优；在属级水平上，热带分布属占保护区非世界分布属的51.92%，温带分布属占46.05%，热带成分有微弱优势，说明该区域的植物区系具有亚热带性质。区系相似性比较分析表明，该区域的种子植物区系与黄桑自然保护区、佛顶山自然保护区、花坪自然保护区的关系较为亲近。 |

| Abstract: |
| Based on field investigation and processing data, 1 178 taxa of seed plants including species, subspecies, varieties and forms, belonging to 492 genera in 147 families were recorded. The floristic compositions and characteristics were analyzed. The results showed that tropical elements and temperate elements covered 65.25% and 34.75% of total families respectively. Obviously, the tropical elements were dominant on the family level. On the genus level, tropical elements and temperate elements covered 51.92% and 46.05% of total genera respectively. The close proportion indicated that the flora of Taipingshan Nature Reserve had subtropical feature. Floristic similarity analysis showed that the ?oristic elements of Taipingshan Nature Reserve were close to Huangsang Nature Reserve, Fodingshan Nature Reserve and Huaping Nature Reserve. |
