福建戴云山国家级自然保护区藓类植物区系研究

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.

Study on the Moss Flora of the Daiyunshan National Nature Reserve,Fujian Province

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.
