| 摘 要： | 苔藓植物是构成山地公园地被景观的重要组成部分，在地表修复和物种多样性等方面发挥着重要的生态作用。以贵阳市山地公园苔藓植物为对象，研究了物种分布组成和与环境的关系。结果表明：贵阳市山地公园苔藓物种丰富度较低，苔藓植物共
有 16 科 24 属 44 种，其中藓纲植物 14 科 22 属 41 种，苔纲植物2 科 2 属 3 种，优势种为齿边同叶藓 Isopterygium serrulatum 、疏网美喙藓 Eurhynchium laxirete 、悬垂青藓 Brachythecium pendulum等 9 种。不同基质上苔藓植物的分布存在显著差异，其中土生苔藓群落最丰富，其次为石生苔藓群落，树生苔藓群落丰度最低；此外，基质及湿度是苔藓植物分布的关键影响因子。

| Abstract: | Bryophyte is an important part of ground cover landscape in mountain parks and plays an important ecological role in surface restoration and species diversity. This paper studies the species distribution composition and the relationship between bryophytes
and the environment in the mountain parks of Guiyang City.The results show that the bryophyte species richness in Guiyang mountain parks is low. There are 44 species, 24 genera and 16 families of bryophytes, including 41 species, 22 genera and 14 families of Musci, and 41 species, 22 genera and 14 families of Hepaticae. There are 9 dominant species, such as Isopterygium serrulatum, Eurhynchium laxirete, Brachythecium pendulum. There are significant differences in the distribution of bryophytes on different substrates, the geophytia is the most abundant,followed by the petrophytia, and the epixylophytia is the lowest.In addition, matrix and humidity are the key factors affecting bryophyte distribution. |
