在白云山自然保护区，调查分析了37种森林类型中影响蕨类植物分布的生境因子以及生境因子与蕨类植物多样性之间的关系。结果表明：（1）在所调查的251块样地内共发现有蕨类植物8609株，分属16科34属90种；（2）生境因子包括森林类型、海拔、坡度、坡向、土壤腐殖质厚度以及凋落物层厚度对物种多样性和群落组成有显著影响；（3）在所调查的生境因子中，森林类型和海拔是最重要的影响因子，其中海拔对多样性的解释量高达11％。此结果表明森林类型和海拔是对蕨类分布起主要作用的环境因子，因此在自然保护区制定多样性保护策略时，应优先考虑植被类型和海拔的影响。

We investigated the habitat parameters affecting Pteridophytes distribution and analyzed the relationship be-tween Pteridophytes diversity and habitat factors for 37 forest types in the Baiyun Mountain National Nature Reserve.The results showed that:(1)8 609 individuals for Pteridophytes with 90 species,34 genera and 16 families were found in all 251 plots investigated.(2)Habitat factors including forest type,elevation,slope,aspect,soil humus thickness, litter layer depth had a significant influence on Pteridophyte species diversity and community composition.(3)Among these factors inside,forest type and elevation were the most important,especially elevation explaining the Pteridophyte diversity of 11%.These results supported that forest type and elevation were the main reasons for the Pteridophytes distri-bution,thus we suggested priority given to vegetation type and altitude when formulating Pteridophytes diversity conserva-tion program in the region.
