| 为探讨贵州亚热带常绿阔叶林树附生藓类植物多样性，以黎平太平山自然保护区为例，对该区树附生藓类植物进行调查研究，共获得432份标本。鉴定及分析结果显示：该区有树附生藓类植物31科89属197种，较之前人对该区苔藓植物的调查工作，新增3个科32个属128个种；优势科包含蔓藓科（Meteoriaceae）、平藓科（Neckeraceae）、青藓科（Brachytheciaceae）、毛锦藓科（Pylaisiadelphaceae）、灰藓科（Hypnaceae）等5个科，优势属有凤尾藓属（Fissidens）、匐灯藓属（Plagiomnium）、青藓属（Brachythecium）、绢藓属（Entodon）、灰藓属（Hypnum）等5个属；树附生藓类植物区系地理成分组成复杂，划分为12种分布类型，东亚分布成分最为丰富，有76种，占总种数的39.79%，热带亚洲分布成分有26种，与其他大洲热带成分相联系的种类达33种，占比17.28%，中国特有成分有16种，占比8.38%；生活型可划分为6种，交织型占主体地位，有88种，占总种数的44.67%。 |

| Abstract: |
| In order to explore the diversity of epiphytic mosses in the subtropical evergreen broad-leaved forest in Guizhou， taking Liping Taipingshan Nature Reserve as an example， 432 specimens of epiphytic mosses were collected. Identification and analysis results showed that there are 31 families， 89 genera and 197 species of epiphytic mosses in this area. Compared with previous work on bryophytes in this area， 3 families， 32 genera and 128 species have been added. 5 dominant families are Meteoriaceae， Neckeraceae， Brachytheciaceae， Pylaisiadelphaceae， and Hypnaceae. 5 dominant genera are Fissidens， Plagiomnium， Brachythecium， Entodon， and Hypnum. Floristic geographic elements are complicated and divided into 12 distribution types. East Asian elements contain 76 species with a proportion of 39.79% of all species.Tropical Asian elements include 26 species. 33 species associated with tropical components on other continents， accounting for 17.28%. There are 16 species endemic to China with a percentage of 8.38% of all species. These species can be classified into 6 life-forms， and the dominant form is wefts containing 88 species with a proportion of 44.67% of all species. |
