摘　　要：通过对贵州赤水桫椤国家级自然保护区藓类植物的标本采集及鉴定分析,该区共有藓类植物26科69属175种;灰藓科(Hypnaceae)、凤尾藓科(Fissidentaceae)、真藓科(Bryaceae)、曲尾藓科(Dicranaceae)、丛藓科(Pottiaceae)、羽藓科(Thuidiaceae)、青藓科(Brachytheciaceae)为该区的优势科;凤尾藓属(Fissidens)、羽藓属(Thuidium)、真藓属(Bryum)、灰藓属(Hypnum)、曲柄藓属(Campylopus)、美喙藓属(Eurhynchium)、毛口藓属(Trichostomum)为该区的优势属;该区区系成分复杂,可划分为16种类型,优势成分为东亚分布成分,占总种数的27.59%,其次是北温带成分,占17.82%,中国特有成分也占有一定比例,占9.20%;生境类型以石生基质种类最多,占到了所有种类的90.86%,其次为土生基质,分布的种类占所有种类的52.00%,树生基质的藓类植物占有一定比例,为10.28%,腐殖质基质的藓类植物种类不多,仅占4.00%。Based on the specimen collection and identification analysis of mosses in Guizhou Chishui Alsophila National Nature Reserve, there were 175 species of mosses belonging to 26 families and 69 genera in this area. Hypnaceae, Fissidentaceae, Bryaceae, Dicranaceae, Pottiaceae, Thuidiaceae and Brachytheciaceae were the predominant families in this region and the dominant genera in this area were Fissidens, Thuidium, Bryum, Hypnum, Campylopus, Eurhynchium and Trichostomum. The flora was complex that 16 types of the flora in this region were recognized. The East Asian distribution component was dominant, accounting for about 27.59% of the total number of species, followed by the north temperate component, that accounted for 17.82%. The certain proportion of endemic components to China was 9.20%. The most habitat types were stone substrates, reached 90.86% of all species, followed by soil matrix, which the distribution of the species accounted for 52.00% of all species. Moss plant in tree matrix occupied certain proportion, accounting for 10.28%, and humus matrix occupied a few moss plant species, accounting for only 4.00%.
