摘要:
首次系统调查了猫儿山自然保护区的藓类植物区系。通过野外考察和室内鉴定,报道广西猫儿山藓类植物39科109属265种(含种下单位),其中广西新记录属6个,新记录种47个。其区系成分以东亚成分为主,占总种数的36.06%,其次为热带亚洲成分和北温带成分,具亚热带性质。将猫儿山自然保护区的藓类植物与四川峨眉山和云南大围山进行比较,结果显示其Gleason物种丰富度指数在三者间最低,Kroeber系数则指示出猫儿山与大围山藓类植物的属、种相似度略高于其与峨眉山的比较值。此外,区系谱的比较反映了猫儿山自然保护区藓类植物区系的东亚成分和其中的中国—日本成分在三者间最高。
Abstract:
Moss flora of Maoershan Nature Reserve in Guangxi Zhuang Autonomous Region is reported for the first time,based on the specimens collected through field survey and careful identification. There are 265 species and infraspecific taxa belonging to 109 genera of 39 families in Maoershan Nature Reserve,among which 6 genera and 47 species are new records to Guangxi. The moss flora of Maoershan Nature Reserve is characterized by subtropical elements. The total elements are ahead by East Asia type representing 36.06% of the entire species,followed by Tropical Asia element and North Temperate element. Gleason Index on biodiversity of mosses of Maoershan Nature Reserve is lower than that of Emei Mountains and Daweishan Nature Reserve. The values of Kroeber index on similarity of genera and species between Maoershan Nature Reserve and Daweishan Nature Reserve are higher than that between Maoershan Nature Reserve and Emei Mountains. The floristic spectrum of Maoershan Nature Reserve shows the highest percentages of elements of East Asia type and SinoJapan subtype,comparing with that of the other two mountains.
