摘要。我们利用55个样地研究了亚马逊地区陆地原生林的植物区系组成。首先，我们利用属和种水平的数据分析了森林的区系格局，发现种水平的分析更明显地区分了森林。其次，我们比较了区域尺度和大陆尺度上样地植物区系组成的变化，发现在区域尺度和大陆尺度上，样地植物区系的平均相似性及其随距离的衰减规律相似。然而，地理距离对区域内植物区系相似性的影响是不同的
Abstract. We explored the floristic composition of terra firme forests across Amazonia using 55 plots. Firstly, we examined the floristic patterns using both genus- and species-level data and found that the species-level analysis more clearly distinguishes among forests. Next, we compared the variation in plot floristic composition at regional- and continental-scales, and found that average among-pair floristic similarity and its decay with distance behave similarly at regional- and continental-scales. Nevertheless, geographical distance had different effects on floristic similarity within regions at distances
