摘要
对山西省蕨类植物区系进行了研究.结果表明,山西蕨类植物共有16科23属46种,区系属于泛北极蕨类植物区,种类稀少,以卷柏科Lycopodiaceae、水龙骨科Polypodiaceae、铁角蕨科Aspleniaceae等科属所含种数相对较多;从种的区系成分看,山西省蕨类植物区系可以划归为6个分布区类型,其中世界分布和热带分布构成了该区系的主体,反映了东亚和热带蕨类植物区系的统一性和紧密联系.
Based on statistics analysis and flora comparison, the fern flora of Shanxi was studied. The re- suits showed that the fern flora of Shanxi Province comprises 46 species of 23 genera in 16 families. The relatively species-rich families are Selaginellaceae, Polypodiaceae and Aspleniaceae. Phytogeographically, the pterido-phyte species of Shanxi can be divided into six areal types and the main elements are of Coemopolitan distribution and Tropical distribution. It reflects the unity and close relationship of the flora of the East Asian and tropicalthe pteridophyle.
