对大巴山木本植物区系进行较为系统的调查研究,结果表明: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”。与邻近地区植物区系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东西两大植物区系的交汇处。
The investigation on the flora of Dabashan woody plants shows that the species rich and transitional are obvious, and a large number of primitive temperate flora and ancient relict flora are concentrated, which is an important “ refuge”. A comparative analysis of the species and floristic components of the flora in the adjacent areas shows that the Dabashan flora should be at the edge of the Central China region and is probably the intersection of the East and West flora of the East Asian flora.
