摘要
本文是对中国、湖南省武陵源蕨类植物初步研究 ,报道了该区系的组成、生态类型、分布的形式并且和相邻地区的关系进行了讨论。在武陵源区有 2 5 6种 (包括变种和变型 ) ,分属 86属 ,38科。属的地理成份可以分为 1 2种类型。武陵源区蕨类植物区系属我国华中华东区 ,它与我国西南区关系最密切。蕨类植物垂直分布可以分为低山、中山和山顶三个带。并指出湖南省西北地区的蕨类植物种类、地理关系。
A preliminary study of the pteridophyte flora of Wulingyuan in Hunan Province, of China is carried out. The floristic compositions, ecological types, distribution and the affinities with its neighbor regions are discussed. In this region, 256 species including varieties and forms of pteridophytes belonging to 86 genera, which are divided into 12 distribution types, in 38 families are recorded. The pteridophyte flora of Wulingyuan is belonging to east and central China region and closely related to southwestern China region.
