六盘水娘娘山国家湿地公园的苔藓植物区系特点

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

摘要:

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）区系类型的物种多于温带（65种，T）区系类型，R/T为112.31%，表现出暖温带向中亚热带过渡的特点。与邻近11个地区的苔藓植物区系谱的比较显示，娘娘山国家湿地公园与八大山最接近，其次是雷公山，此结果表明，娘娘山的苔藓植物区系符合其所处地理位置。中国特有种为喜马拉雅起源，主要向东迁移，其次向北迁移。迁移路线与慈巴沟的最相似，可能与地理位置、气候及自身的生物学特性有关。

Abstract:

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.
