摘要
赤水河谷上游是国酒茅台的水源地,是典型的亚热带河谷地带。通过对该地区201号标本的初步鉴定和统计,发现苔藓植物共计17科32属66种(含变种),苔门植物有5科6属9种;藓门植物有11科25属56种;角苔门植物1科1属1种[褐角苔Folioceros fusciformis(Mont.)Bharadw.]。生活型有3种:矮丛集型(68.18%),平铺型(13.64%)和交织型(18.18%),其中矮丛集型明显占有绝对优势,这可能与该地区亚热带河谷气候和植被有一定关系。区系地理成分共有13种类型,除世界广布成分外,该地区热带亚洲成分(25.49%),北温带成分(21.57%),中国特有种(15.67%)和东亚成分(15.67%)占有一定优势。
Chishui River Valley upstream is the waterhead area of Chinese Moutai and is a typical subtropical Valley.After our preliminary identification and statistic,201 samples of bryophytes were collected from the area.we found that bryophytes were 66 taxa which belong to 17 families and 32 genera.Thereinto,there are 9 taxa of liverworts in 6 genera of 5 families;56 taxa of Mosses in 25 genera of 11 families;1 taxa of hornworts in 1 genus of 1 family [Folioceros fusciformis(Mont.)Bharadw.].The life-forms are Short turfs(68.18%),Mats(13.64%) and Wefts(18.18%) and Short turfs holds absolute dominant.This may be have a certain relationship with the subtropical valleys of climate and vegetation.The flora of bryophytes were complex,including 13 types in this studied area.Except Cosmopolitan elements,Tropical Asia element(25.49%),North temperate zone element(21.57%),Endemic to China(15.67%)and Eastern Asia element(15.67%)were the dominant elements.
