喀斯特山地高校苔藓植物多样性及环境响应——以贵州大学为例

以贵州大学喀斯特山地校园为对象，调查其苔藓植物物种多样性及其生境特征，探讨苔藓植物生长与环境的关系。结果表明，研究区域内苔藓植物共12科27属51种。优势科是丛藓科(Pottiaceae)、青藓科(Brachytheciaceae)和灰藓科(Hypnaceae)；主要生活型为丛集型、交织型和垫型；不同功能区域的苔藓植物生物多样性从高到低依次为行政办公区、休闲游憩区、教学科研区、体育运动区、宿舍休息区；不同生境物种丰富度从高到低依次是疏林草坪、林下、草坪环境、灌丛花池、道路；人为干扰程度与光照、湿度是影响苔藓植物多样性组成的重要因子。研究区域内苔藓植物多样性较低，多为土生藓类。在苔藓生长的微生境中，人为干扰低、空气湿度大的林地、疏林草坪更利于苔藓生长。

Bryophyte Diversity and Environmental Response in University Campuses in Karst Mountainous Regions:

In this paper, the species diversity and habitat characteristics of bryophytes in universities in Karst mountains were studied, and the relationship between bryophyte growth and environment was discussed. The results showed that there were 51 species of bryophytes belonging to 27 genera in 12 families. The dominant families were Pottiaceae, Brachytheciaceae and Hypnaceae. The main life forms were clustered, interlaced and cushion. The order of biodiversity in different function zones from high to low was administrative office area, leisure area, teaching and scientific research area, sports area, dormitory rest area. The order of species richness in different habitats from high to low was open forest lawn, underforest, lawn environment, shrub pond, road. The degree of human disturbance, light and humidity were important factors that change the diversity composition of bryophytes. In conclusion, the bryophyte diversity in Guizhou University was low, and most bryophytes were native mosses. In the microhabitat of moss growth, woodland and open forest lawn with low disturbance and high air humidity were more conducive to moss growth.
