摘要
对贵州省松桃县水银厂的苔藓植物群落进行了研究,通过野外全面调查和实验室鉴定,发现贵州松桃水银厂苔藓植物群落的种类组成有8科15属34种(苔类植物1科1属1种,藓类植物7科14属33种);生活型含矮丛集型、交织型和平铺型3种类型,其中矮丛集型占优势(88%);区系地理成分共8种,以世界广布种(24%)、北温带成分(21%)和中国特有种(18%)占优势;北地扭口藓群落(Barbula fallax Com.)、毛口藓-北地扭口藓群落(Trichostomum brachydontium-Barbula fallax Com.)、狭网真藓群落(Bryum algovicum Com.)为该矿区的优势群落,具有治理废弃矿山的潜在价值,可利用它们作为金属矿山生态修复进一步研究的素材。
The bryophyte communities were investigated at Shuiyinchang Mercury Mine in Songtao county,Guizhou province.Based on the extensive investigation and identify of the bryophyte specimens,34 taxa in 15 genera of 8 families were found（1 species in 1genus and 1 family is Hepaticae,33 taxa in 14 genera and 7 families are Musci）.The life-forms are Short turfs,Wefts and Mats,Short turfs is the dominant life-forms（88%）.The phytogeographical elements of bryoflora can be classified into eight types.Among them,Cosmopolitans（24%）,North temperate zone（21%） and Endemic to China（18%） are the dominant phytogeographical elements.The dominant communities are Barbula fallax Com.,Trichostomum brachydontium-Barbula fallax Com.and Bryum algovicum Com.,they grow so well in the mine that have the potential of ecological restoration.
