在野外调查和已有资料的基础上,对巴山地区蕨类植物的区系和分布进行了系统的分析.结果表明,该区具有蕨类植物34科,79属,289种(包括变种和变型).区系地理成分复杂,在属的水平上以热带、亚热带成分为主,约占总属数的60.87%,温带成分占39.13%,而在种的水平上,热带、亚热带成分仅占总数的8.77%,温带成分处于优势地位,为91.23%,在温带成分中,东亚成分突出,加上中国特有成分共占总数的86.67%,显然应是东亚区系的一部分,因此巴山蕨类植物区系应属于中国-日本蕨类植物亚区.垂直分布可以划分3个带,蕨类植物主要分布在海拔1 000~1 800m.
在野外調查和已有資料的基礎上,對巴山地區蕨類植物的區繫和分佈進行瞭繫統的分析.結果錶明,該區具有蕨類植物34科,79屬,289種(包括變種和變型).區繫地理成分複雜,在屬的水平上以熱帶、亞熱帶成分為主,約佔總屬數的60.87%,溫帶成分佔39.13%,而在種的水平上,熱帶、亞熱帶成分僅佔總數的8.77%,溫帶成分處于優勢地位,為91.23%,在溫帶成分中,東亞成分突齣,加上中國特有成分共佔總數的86.67%,顯然應是東亞區繫的一部分,因此巴山蕨類植物區繫應屬于中國-日本蕨類植物亞區.垂直分佈可以劃分3箇帶,蕨類植物主要分佈在海拔1 000~1 800m.

Based on the field survey and the known data,the flora and distribution of the pteridophytes in Ba Mountains were analyzed. The result were showed that there were about 289 species (including varieties and forms),79 genera and 34 families of pteridophytes in this region. Floristic and geographic elements are complicated. At genus level,tropical-subtropical distribution types were dominant,accounting for 60.87% of the total genera,and temperate distribution types covered 39.13% of the total. While at the species level,temperate elements were dominant,accounting for 91.23% of the total species,and tropical-subtropical elements covered 8.77% of the total. Of the temperate elements,East Asian element took the largest proportion,including endemic to China,accounting for 86.67% of the total species in the mountains,which indicated that Ba Mountains belonged to China-Japan Sub-zone of pteridophytes. The pteridophytes of Ba Mountains can be divided into 3 altitudinal zones,and their vertical distribution center occured between 1 000-1 800 m above sea level.
