湖北七姊妹山国家级自然保护区苔类植物区系

对湖北七姊妹山国家级自然保护区进行野外调查，共采集苔类植物标本210份。经过室内鉴定与统计，发现该区域苔类植物共有26科33属51种。其中，15种为湖北省新记录种，裸蒴苔科Haplomitriaceae为湖北省新记录科；假护蒴苔属Metacalypogeia和裸蒴苔属Haplomitrium为湖北新记录属。该区域苔类植物区系类型成分复杂，多种区系成分并存，可划分为10类，其中以北温带成分为主，东亚成分次之。另外，与其他保护区比较，七姊妹山与清凉峰物种相似度最高，与十大万山相似度最低。地理位置相近的保护区，其苔类植物区系成分比较接近，且区域气候环境也会影响植物种类和区系特征。该研究为七姊妹山国家级自然保护区乃至湖北省苔藓植物种类多样性、区系研究，以及苔藓植物资源保护提供基础资料。

Liverwort flora of the Qizimei Mountain National Nature Reserve in Hubei Province

This research collected 210 liverworts specimens in the Qizimei Mountain National Nature Reserve. A total of 51 species belonging to 33 genera in 26 families, were identified and recorded in the research site, among which 15 species were new records for Hubei Province. The family Haplomitriaceae and two genera Metacalypogeia and Haplomitrium were also new for Hubei. The floristic elements of liverworts in the research site were complex, belonging to 10 different distribution elements. North temperate and Eastern Asian were two main elements. Comparison with other nature reserves in species similarity showed a highest similarity between the Qizimei and Qingliangfeng, a lowest value with Shiwandashan natural reserve. The geographical proximity resulted in a high similarity of floristic elements. Regional climate environment could affect plant species and floristic features. The study provided basic information of species diversity, floristic study, and protection of bryophytes for the Qizimei Mountain National Nature Reserve and Hubei Province.
