| 摘 要： | 本研究利用野外考察信息和文献资料探讨了苍山西坡漾濞地区种子植物区系成分的垂直分布格局,结果表明,热带区系成分所占比重随着海拔的升高呈明显递减趋势,这与热带区系植物喜温的生态特性是一致的。温带区系成分所占比重总体上随着海拔的升高呈明显递增趋势,这与温带区系植物耐低温的生态特性是一致的。中国分布成分所占比重随着海拔的升高呈明显的递增趋势,具有温带植物区系的性质。随着海拔的升高,区系过渡性先呈递增趋势,然后呈递减趋势,在海拔2100 m-2200 m之间,区系过渡性达到峰值。

| Abstract: | The altitudinal patterns of flora composition of seed plants in Yangbi area,west slope of Cangshan Mountain were investigated based on field survey and literature.The results showed that tropical elements decreased with the increase of altitude,which was consistent to their ecological characters.And temperate elements increased with the increase of elevation,which was consistent to their strong adapt to cold environment.Flora endemic to China increased with the increase of altitude,showing temperate charact... |
