中国石蕊科地衣多样性与区系研究

Species diversity and floristic elements of the lichen family Cladoniaceae in China

  • 摘要: 通过实地调查我国华北、西南等地区的石蕊科地衣多样性,结合前人的研究资料,从物种多样性、生境、区系成分等多方面对我国石蕊科地衣进行研究。结果显示,我国石蕊科地衣共有5属107种,其中石蕊属(Cladonia)占优势,有94种,占石蕊科地衣总种数的87.9%。共鉴定出山西省新记录8种,云南省新记录种3种。石蕊科地衣生境共分为5种:藓丛生、树生、草地生、石生和多生境,其中多生境占比最高(49.5%)。我国石蕊科地衣区系成分多样共分为7种,包括:世界广布成分(除外)、环北极成分(37.8%)、泛热带成分(12.2%)、欧亚成分(6.1%)、东亚-北美成分(9.8%)、东亚成分(24.3%)和中国特有成分(9.8%)。

     

    Abstract: We studied the species diversity, habitat, and floristic elements of the lichen family Cladoniaceae from southwest and north China according to field investigations and published literature. Results showed that there were 107 species, belonging to five genera. Cladina (Cl) was the dominant genus, accounting for 87.9% of total species. Among them, eight and three species were reported for the first time in Shanxi and Yunnan, respectively. Five habitat types were categorized:i.e., mossland, woodland, grassland, rocks and multi-habitats, with variety-habitats accounting for the highest proportion (49.5%). The floristic composition of lichen was diverse, with seven floristic elements identified, including Cosmopolitan element (excluded), Circumpolar element (37.8%), Pantropical element (12.2%), Eurasian element (6.1%), East Asian-North America element (9.8%), East Asian element (24.3%) and Chinese endemic element (9.8%).
