| 摘要: |
| 通过调查统计,广西拉沟自然保护区共有野生种子植物153科594属985种。种子植物区系组成丰富,地理成分复杂,具有中亚热带向南热带过渡性质。在科、属水平上对植物区系特性进行了统计分析,热带性质均强于温带性质,属的成分以泛热带分布、热带亚洲分布为主。与邻近地区植物区系相比较,拉沟自然保护区与广西大瑶山自然保护区相似性较高,与广西花坪自然保护区相似性较低。 |

| Abstract: |
| The statistics and floristic study of Lagou Nature Reserve was reported in this paper. The results indicated that the seed plants were bundant,represented by 985 species,belonging to 594 genera in 153 families. The reserve was in transitional region of center and southern subtropical zone,and was characterized by rich floristic components and complex phytogeographical elements. In addition,the statistics and results obtained from their intensive analyses at different levels revealed that the tropic elements were slightly higher than temperate elements,and the main geographical elements of the genera were Pantropic and E.Asia. Last,compared with its neighboring floras,the flora of Lagou Nature Reserve was closely related to Dayaoshan Nature Reserve,but distantly related to that of Huaping Nature Reserve. |
