中文摘要：

通过3次野外实地考察采得藓类植物标本2198份,经室内鉴定,戴云山国家级自然保护区藓类植物共计47科、130属、302种（含种下单位）,其中福建省新纪录3科、11属、74种。经区系成分分析,戴云山以东亚成分为主,占总种数的33.33%;其次是热带亚洲成分和北温带成分,分别占总种数的22.22%和16.67%,具亚热带性质。将戴云山与台湾玉山、江西阳际峰、浙江大盘山、广西猫儿山、广西九万山、福建鹫峰山东麓、云南大围山和四川峨眉山的藓类植物区系成分比较发现,戴云山的藓类植物区系成分更具岭南区特色。聚类分析结果也表明,戴云山与岭南区的猫儿山、九万山、大围山和毗邻区——云贵区的峨眉山聚在一起,因此,建议将岭南区与华东区在福建省内的界限略向北移。

英文摘要：

Based on field investigation and identification of 2198 collected samples,302 species（including infraspecific taxa） belonging to 130 genera of 47 families in Daiyunshan National Nature Reserve were identified,among which 3 families,11 genera,and 74 species were new records to Fujian province.The moss flora of Daiyunshan was characterized by sub-tropical elements.The total elements dominated by East Asia type,representing 33.33% of the entire species,followed by Tropical Asia element（22.22%） and North Temperate element（16.67%）.The result showed that Daiyunshan had more characteristics of Linnan Region through the comparsion of the moss flora of Daiyunshan with Yushan（Taiwan province）,Yangjifeng（Jiangxi province）,Dapanshan（Zhejiang province）,Maoershan（Guangxi pro-vince）,Jiuwanshan（Guangxi province）,Eastern Jiufengshan（Fujian province）,Daweishan（Yunnan province） and Emeishan（Sichuan province）.Cluster Analysis of these 9 regions showed that Daiyunshan was closer to Maoershan,Jiuwanshan,Daweishan from Lingnan Region,and nearby Emeishan.Therefore,we suggest that the boundaries between Lingnan Region and East China Region should be slightly moved northward.
