为了解娘娘山国家湿地公园苔藓植物区系特点,对苔藓植物的物种组成和中国特有种的迁移特点进行了研究.结果表明,湿地公园共有苔藓植物51科106属266种(含12变种),易危苔藓植物2种.苔藓植物区系可划分为17种类型,以北温带分布(17.37％)占优势,其次是热带亚洲分布(14.83％).属于热带(73种.R)区系类型的物...

Bryoflora Characteristics in Niangniang Mountain National Wetland Park, Liupanshui, Guizhou

To understand floristic characteristics of bryophytes in Niangniang Mountain National Wetland Park, Liupanshui, the species composition of bryophytes and migration routes of Chinese Endemic were studied. The results showed that there were 266 species (including 12 varieties), belonging to 51 families and 106 genera, including 2 vulnerable species. The bryophyte floristic could be divided into 17 areal-types, the North Temperate (17.37%) was dominant, followed by the Tropical Asia (14.83%). There were more species belonging to tropical areal-types (73 species, R) than temperate areal-types (65 species, T), the R/T was 112.31%. It has the characteristics of the warm-temperate zone to the middle-subtropical zone. Compared with 11 neighboring regions, the bryophytes floristic spectrum of Niangniang Mountain was the most closest to that of Bada Mountain, followed by that of Leigong Mountain. These results showed that the bryoflora of Niangniang Mountain corresponded to its geographical location. The Chinese Endemic of bryophytes was of Himalayan origin and mainly migrate eastward and northward. The migration routes of bryophytes Chinese Endemic was the most similar to Cibagou, the reasons might be related to geographical location, climate and its own biological characteristics.
