摘　　要：在野外调查和已有资料整理的基础上,分析了英山吴家山国家级森林公园蕨类植物区系组成和分布区类型。结果表明,吴家山共有蕨类植物68种(包括变种),隶属于23科、39属;科的分布类型以世界分布和热带—亚热带分布为主;属的分布以泛热带和热带亚洲分布属为主,同时也表现出强烈的暖温带性质;种的分布以东亚类型为主,特别是中国—日本分布类型最多,亚热带至暖温带性质明显。该区应置于中国—日本森林植物亚区从暖温带向亚热带过渡的范围内,与当地所处的地理位置相符合。Based-on the known data and the field investigation,the composition and distribution types of pteridophyte flora in Wujiashan National Forest Park which is situated in the eastern part of Hubei Province in China were analyzed. The pteridophytic flora in Wujiashan National Forest Park were reported to be composed of 68 species（ including of varieties）, which belonged to 39 genera and 23 families. The top families distribution types were cosmopolitan and tropic-subtropic ones;the main genera distribution types were pantropical and tropic Asia ones,but temperate ones were showed intesenly while the species distribution type belonged to the east Asia type and represents the feature of subtropics transition to warm tempemted area-type. Based on the analysis of geographic compositions of genera and species, the results showed that the region was a part of the center of East-Asian elements（especially ChinaJapan element）. So it is filled for the geographical position of this area.
