摘要
研究旨在完善苔藓植物景观适宜性评价方法,为提升公园苔藓植物景观空间布局质量提供理论支撑。通过主成分分析法得到各级指标的贡献率及综合得分,苔藓植物群落类型适宜性由高到低表现为树生群落>石生群落>土生群落;各指标对苔藓景观适宜性的影响由强到弱表现为景观适宜性>社会适宜性>生态适宜性;丛集型+交织型+平伏型、平伏型+交织型、丛集型+交织型、倾斜型+平伏型+交织型组合形式的苔藓植物群落适宜性好,交织型、丛集型+交织型、倾斜型+交织型的组合形式的苔藓植物群落适宜性差。合理掌握景观适宜、生态适宜和社会适宜三者间的均衡统一,是苔藓植物景观保护与营建的关键所在,在设计中多采用适宜性好的苔藓群落配植形式。
The purpose of this study is to improve the evaluation method of bryophyte landscape suitability and to provide theoretical support for improving the spatial layout quality of bryophyte landscape in the park.The contribution rate and comprehensive score of all indexes were obtained by principal component analysis,and the suitability of bryophyte community types from high to low was tree community>stone community>soil community.The influence of each index on the suitability of bryophyte landscape was from strong to weak as follows:landscape suitability>social suitability>ecological suitability.The combination of turf+weft+mat,mat+weft,turf+weft,pendant+mat+weft bryophyte communities had good suitability.The combination of weft,turf+weft,pendant+weft bryophyte communities had bad suitability.The key to the protection and construction of the bryophyte landscape is to reasonably grasp the balance and unity among landscape suitability,ecological suitability and social suitability.Thesuitablebryophyte community collocation form shouldbe adopted inthe design.
