摘要
作者在对安徽省进行实地考察和采集的2000余号苔藓植物标本的基础上,经过研究鉴定,并收集整理了有关安徽藓类的资料,对照现有文献,发现安徽已知藓类植物有46科、164属、545种(包括8亚种和32变种),其中新记录95种(包括3变种1亚种);青藓科为安徽省藓类第一大科,含9属52种,占总种数的9.6,青藓属是第一大属,包括有29种,占总种数5.3;科内种数(≥19种)优势科有10个,属内种数(≥6种)的优势属有22个。在安徽省藓类区系中,以东亚成分为主并占了28.6、北温带成分占23.0、热带亚洲成分占17.8,温带亚洲成分为10.6,中国特有成分占到10.4,这5种区系成分都超过10,它们是本省最主要的区系地理成分。
Anhui Province, located in the middle lower reaches of the Yangtze River, covers an area of 139600 km^2 . The Yangtze river and the Huaihe river are the most important water courses traversing the province. Based on the literature available and identification of over 2000 collections of bryophytes made by the authors from the province in 2006 and 2007, we found that there are 545 species (including 8 subspecies and 32 varieties) belonging to 164 genera and 46 families. Among them, 95 species, 3 varieties and 1 subspecies are new to Anhui Province. An analysis of geographical and floristic elements of Anhui Province mosses indicates that 143 species (28.6% of the total) belong to the East Asian Elements, 115 species (23.0% of the total) the North temperate Elements, 89 (17.8% of the total) the Tropical Asian Elements, 53 species (10.60% of the total) the Temperate Asian Elements and 52 (10.4% of the total) Chinese Endemic Elements. East Asian Elements are the most important ones. To all appearances, the mossflora of Anhui Province is provided with obvious temperate characters, and there are characteristics of subtropical and temperate zone.
