摘　　要：为进一步探讨我国瓶口衣科地衣物种组成及区系成分特征。通过实地调查我国西北、华北和西南等地区的瓶口衣科地衣资源,分析其物种组成及地理成分特征,共鉴定出省级新记录属1属,省级新记录种7种。结合已有的研究报道,从物种多样性、空间分布、生境类型等多方面对我国瓶口衣科地衣的区系特征进行研究。结果表明:我国瓶口衣科地衣共有20属140种,瓶口衣属(Verrucaria Schrad.)占主要优势,约占瓶口衣科地衣总种数的37.14%。瓶口衣科地衣多分布于我国西北、西南、华南和台湾地区。瓶口衣科地衣生境类型有石生地衣、树生地衣、土生地衣和多生境地衣4种,以石生地衣为主(78.20%)。瓶口衣科地衣区系成分主要有6种,包括:世界广布成分、环北极成分、东亚成分、地中海-西亚-中亚成分、温带成分和中国特有成分。我国瓶口衣科地衣以瓶口衣属为优势属,区系成分多样,中国特色明显,环北极性质显著。我国西北地区与华北地区瓶口衣科地衣物种相似性最高,西北地区在区系成分聚类分析中单独为一组。该研究为瓶口衣科地衣的研究提供了重要的理论基础资料。To further discuss the species composition and floristic characteristics of the Verrucariaceae in China,we studied the species diversity,distribution,habitat and floristic elements of the Verrucariaceae from Northwest China,North China and Southwest China according to field investigations and published literature.Among them,1 genus and 7 species were identified as new records at the provincial level.The results show that:There are 140 species,belonging to 20 genera.Verrucaria is the dominant genus,accounting for about 37.14% of total species.Lichens in Verrucariaceae were mostly distributed in Northwest and Southwest China,South China and Taiwan of China.4 habitat types are categorized:rocks,trees,soils and multi-habitats,with rocks accounting for the highest proportion(78.20%).The floristic composition of lichen is diverse,with 7 floristic elements identified,including Cosmopolitan element,Circumpolar element,East Asian element,Mediterranean-West Asian-Central Asian element,Temperate element and Chinese endemic element.In china,the dominant genus in the Verrucariaceae is Verrucaria,and the geographical composition is complex.The Chinese endemic element is the most prominent,with obvious Circumpolar element characteristics.The highest similarity in the species of the Verrucariaceae between the Northwest China and North China is observed,and it forms a distinct group in Northwest China according to the cluster analysis of floristic composition.This study provides a crucial theoretical foundation for research on the Verrucariaceae.
