中文摘要：
对中国产蹄盖蕨属（Athyrium Roth）进行较为系统的区系地理学分析。结果表明，国产蹄盖蕨属所包含的130种（含变种）可划分为热带亚洲分布、东亚分布和中国特有3大类型。其中，中国特有比例最高，其次是东亚分布，只有个别种为热带亚洲分布。特有种分布最多的地区是横断山脉地区。因此，国产蹄盖蕨属全部分布在亚洲，而横断山脉地区是其分布中心和分化中心，但起源地可能在北方，属温带起源。进行蹄盖蕨属的区系地理学分析，对研究该属的系统分类、起源演化有重要意义。
英文摘要：
In this paper, we conducted a preliminary analysis on the geographic distribution and areal-type （including subtypes） of Chinese Athyrium Roth. In China, there were about 130 species （including varieties） that belonged to the areal-types of Tropical Asia, East Asia, and Endemic to China. Except a few species which belonged to Tropical Asia areal-type, most of them were endemic to China, and a part of them distributed in the East Asia. Most of endemic species occured in the Hengduan Mountains. Therefore all species of Chinese Athyrium Roth had distribution in Asia. The Hengduan Mountains were regarded as the centers of their distribution and differentiation, but they might origin from further north. Their origin center was possibly boreal in temperate flora. Analysis of floristie geography of the genus was one of the useful methods for studying the taxonomy and deducing the evolution of these species.
