| 摘 要： | 本文通过详细的植物类群调查,对大巴山木本植物区系进行了较为系统的研究。结果表明,大巴山木本植物区系种类丰富,过渡性明显,集中了大量原始温带植物区系成分和古老孑遗植物成分,是我国第三纪植物区系的重要“避难所”。通过对该区植物区系与邻近地区植物区系之间共有种和区系成分的对比分析,表明大巴山植物区系应属华中区边缘,很可能是东亚植物区系的东西两大植物区系的交汇处。

| Abstract: | Research was made into the woody floras on the Dabai Mountains by detailed investigation of plant groups. Results have shown that the woody floras have plenty of species, displaying an obvious transitional feature. In addition,the Dabai Mountains hold a number of floral components of the primitive temperate zone and relict plant components,thus being an important "sanctuary" in China for the floras of the Tertiary period. This paper also makes a comparative analysis of common species and floral components in the Dabai Mountains and the neighbouring areas. The results indicate that the floras on the Dabai Mountains should belong to the edge floras of the Central China Zone,and the Dabai Mountains are possible to be a junction place of the east and west floras of the East Asian Flora. |
