中国贵州与日本蕨类植物区系之比较(英文)

Comparison of the pteridophyte floras of Guizhou Province, China, and Japan

中国贵州与日本基本上具有相同科、属的蕨类植物，两地的大科完全一致。日本比贵州有较多的热带与温带属，反映了其温和的海洋性气候及南伸北延的岛屿跨越纬度范围较大，贵州则因地处大陆及亚热带气候而有不同的蕨类植物。尽管如此，贵州有295种，或占总数39％的蕨种日本也有。在鳞毛蕨属（Dryopteriss）中，贵州有24种或47％与日本共有，而在耳蕨属（Polystichum）中仅23％或11种与日本相同。这两属的分布差异是基于物种的生态选择：鳞毛蕨属内多为喜酸性种类，而耳蕨属的种类主要是喜钙性植物。

Guizhou Province, China, and Japan share essentially the same families and genera of pteridophytes, with the largest families being the same in the two regions. Japan has more tripical and temperate genera than Guizhou, probably reflecting its moderate maritime climate in the south and the archipelago's greater latitudinal range. Guizhou's pteridophyte flora reflects its continental location and subtropical climate. Nevertheless, 295 species, aboat 39 percent of the ferns in Guizhou, are also in Japan. Ih Dryopteris, 24 species, 47 percent of the total in Guizhou, are conmmon to the two regions, but only 23 percent, or 11 species of polystichum are shared between Guizhou and Japan. The differences in distribution of these two genera are thought to be based on ecological preferences of the species, the species of Dryopteris being acidophiles mostly, While the species of Polystichum are mainly caciphiles.
