摘要
对苏州11个主要园林中的苔藓植物进行了调查,报道了苔藓植物23科42属90种,从种类组成、生境特点、区系成分和园林间种类差异等方面分析了苔藓植物多样性.结果表明:相比上海、无锡市,苏州园林内苔藓植物石生、树生种类所占比例较高,假山和盆景中种类是其特色.种的区系成分分析表明,该地区苔藓植物以东亚成分为主,北温带成分也占较大比例,具有典型的东亚特色.基于苔藓多样性的聚类分析可将园林分成5组,与园林面积、布局和生境特点等因素有关.建议加强对园林内苔藓植物的研究,并推广其在园林设计中的应用.
Based on the field investigation in 11 major gardens of Suzhou,90 species in 42 genera and 23 families of bryophytes were reported in the present paper,and the species composition,habitat characteristics, floral elements and species difference among the gardens were analyzed. The results showed that the proportion of epixylophyte and petrophyte species in Suzhou Gardens is larger than that in the city of Shanghai and Wuxi,and bryophytes feathered on rockery and bonsai. The statistical analysis of the floral elements of its species revealed that it has a dominant majority of east Asian elements and a proportion of temperate elements, which reflects a typical east Asian characteristic, 11 gardens can be divided into 5 groups by cluster analysis based on bryophyte diversity,related to their area,patterns and habitats. Studies and applications of bryophytes in gardens should be enhanced.
