摘要
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。
A systematical study on the woody plant flora in the Daba Mountains was pursued in this paper by means of an investigation on plant taxa.The result shous that the woody plant flora of the area is very abundant in species and very obvious in transition nature.As an area full of primitive temperate plants and ancient relic plants,this region shows itself to be an important refuge of tertiary flora.Based on the contrastive analyses on the floristic elements,and the common plant species between the Daba Mountains and the adjacent floristic regions,the authors believe that the plant flora of the Daba Mountains must be an edge of Central China Flora,and that it is likely to be the joint be- tween the sino-Himalayan and the Sino-Japanese patterns phytogeographically.
