摘 要 ：通过对中国四川王朗国家级自然保护区藓类植物连续2年的野外调查，结合室内鉴定及文献研究，分析了王朗自然保护区藓类植物区系组成及其特点，探讨藓类植物在不同林分类型（原始林、次生林、人工林）下的分布，并通过对王朗自然保护区与周围6个地区（玉树、佛坪、神农架、峨眉山、金佛山、大围山）藓类植物的比较，揭示王朗自然保护区藓类与周围地区藓类植物的关系。研究结果表明：（1）王朗自然保护区藓类植物物种丰富度较高，涵盖藓类植物33科、111属、227种（包括5个变种）。（2）王朗自然保护区藓类植物区系中，北温带分布、东亚分布及中国特有种占有优势。（3）王朗自然保护区不同林分类型下，藓类植物的种类有明显的差异性，共有属40个（占王朗自然保护区藓类总属数的36.04%），非共有属71个（占王朗自然保护区藓类总属数的63.96%），且不同林分类型下，次生林藓类物种丰富度最高、原始林次之、人工林最少。（4）王朗自然保护区与佛坪、峨眉山自然保护区的藓类植物具有明显的相似性，其中，属的相似性系数达到60%以上，种的相似性系数在35%以上。

Abstract:According to two years’ field investigation,identification and literature survey,we discussed mosses floral composition and their characteristics in Wanglang National Nature Reserve,Sichuan Province,China.Then we clarified their distribution in different forest types (virgin forest,secondary forest,and the planted forest).By comparing the data of the mosses in Wanglang Nature Reserve and other six areas around (Yushu,Foping,Shennongjia,Mt.Emei,Mt.Jinfu,Mt.Dawei),this paper summarized the relationships between Wanglang Nature Reserve and the other six areas around.Conclusions can be summarized as follows:(1)Species of mosses in Wanglang Nature Reserve were rich.A totle of 227 species (including five varieties) belonging to 33 families,111 genera were found.(2)The dominate mosses floras of Wanglang Nature Reserve were North Temperate,East Asia,and Endemic to China.(3)The mosses genera of Wanglang Nature Reserve were obviously different in different forest types.The number of common genera was 40 (36.04% of the number of total genera of mosses in Wanglang Nature Reserve),and that of uncommon genera was 71 (63.96% of the number of total genera of mosses in Wanglang Nature Reserve).And,among the three different forest types,secondary forest had the highest species richness,followed by the virgin forest,and then the planted forest.(4)Mosses in Wanglang Nature Reserve were similar to Foping and Mt.Emei Nature Reserve.The similarity coefficient of genus reached up to 60%,and the similarity coefficient of species was more than 35%.
