英文摘要 【Objective】 To explore the regulating effects of park environmental characteristics on ground bryophyte diversity and reveal the spatial differentiation of bryophyte diversity driven by environmental factors inside and outside parks, with the aim to provide a basis for conservation and management of urban bryophyte diversity. 【Method】 This study investigates ground bryophytes across 16 parks in the core area of Hefei City, and analyzes their distribution patterns, species diversity, community composition and influencing factors in the urban environment. 【Result】 1) A total of 36 bryophyte species in 23 genera of 16 families are investigated, including 34 mosses and 2 liverworts. The dominant families include Pottiaceae and Brachytheciaceae, the dominant genera are Fissidens, Brachythecium, and Bryum, and the dominant species include Haplocladium microphyllum and Barbula unguiculata; 2) Species richness is positively driven by the total park area, green space area, and water body coverage within a 100-meter buffer zone, whereas species abundance exhibits significant correlations with the green space area of the buffer zone at different distances (50-1 000 meters) and the water area within a 200-meter buffer zone; and 3) Redundancy analysis (RDA) identifies that the distance from the city center and park area are the main drivers of bryophyte community composition in urban parks. 【Conclusion】 The park environmental characteristics have an important impact on the survival and development of bryophytes. For future urban bryophyte conservation and application, a synergistic strategy integrating core habitat management and peripheral buffer zone optimization is proposed, emphasizing the combined effects of internal and external environmental characteristics to enhance biodiversity conservation and utilization.
