| 摘 要： | 以大尺度的物种分布信息为基础,探讨了云南地区棕榈科植物多样性的地理分布格局。结果表明,云南地区的棕榈科植物大多数为狭域分布物种;在海拔梯度上,从低海拔到高海拔,棕榈科植物多样性呈递减趋势;在纬度梯度上,从南到北,该科植物多样性亦呈逐渐递减的分布格局。棕榈科植物的多样性分布格局与该科植物起源于热带地区以及由此决定的生态特性有关。

| Abstract: | Based on flora information in large scale,spatial patterns of species diversity of Palmae in Yunnan were investigated.The results showed that most of species of Palmae were of narrow domain.With the increase of altitude,a decreasing trend was observed on species diversity of Palmae.On latitudinal gradients,a decreasing trend of species diversity was found from south to north.The spatial patterns was probably due to the origin of Palmae. |
