利用云南地区蕨类植物物种的大尺度分布信息，结合地理信息系统及统计学分析，探讨了云南地区蕨类植物多样性及其区系分布格局。结果表明，从科到属和种的水平，研究区域内蕨类植物多样性数据集的离散系数呈递增趋势。在科、属和种的水平上，蕨类植物多样性的高值区域均出现在滇西北部分地区、滇南及滇东南等地区，但在属和种的水平上，高值区域更为明显。蕨类植物的区系分化强度呈现出与其多样性相似的分布格局。与科水平相比，在属和种的水平上，云南地区蕨类植物多样性的空间变异程度更加明显。珍稀、濒危蕨类植物主要分布在滇东南、滇南及滇中的部分地区。

Based on distribution information of pteridophytes , spatial patterns of pteridophytes diversity and floris-tic differentiation were investigated in Yunnan , with the help of geographic information system and statistical analy-sis.The results showed that there was an increasing trend of dispersion coefficient of pteridophytes diversity from family to genus and species level.At family, genus and species level, spatial patterns of pteridophytes diversity were higher at South Yunnan, Southeast Yunnan and some parts of Northwest Yunnan, and more pronounced high-er diversity regions at genus and species levels.Spatial patterns of floristic differentiation were generally consistent with those of diversity pattern.Compared with those at family level, there was higher variations of pteridophytes di-versity at genus and species levels.Higher diversity of rare and endangered pteridophytes in Yunnan was mostly ob-served at South Yunnan, Southeast Yunnan and Central Yunnan.
