摘　　要：【目的】了解叶附生苔类植物在中国就地保护中是否存在保护空缺。【方法】在浙江省庆元县开展对百山祖国家公园及周边生境适宜地区的叶附生苔类植物的系统调查,比较叶附生苔在公园内外的多样性、分布情况、物种组成特点及相似性。【结果】①共调查记录叶附生苔类植物4科11属25种,包括细鳞苔科Lejeuneaceae(21种)、扁萼苔科Radulaceae(2种)、叉苔科Metzgeriaceae(1种)和耳叶苔科Frullaniaceae(1种)。细鳞苔科为该地区的优势科,疣鳞苔属Cololejeunea为该地区的优势属。鳞叶疣鳞苔Cololejeunea longifolia和尖叶薄鳞苔Leptolejeunea subacuta为该地区常见种。②在所获得的4科11属25种叶附生苔中,分布于百山祖国家公园内的有4科9属14种,分布在百山祖国家公园外的有2科7属14种,但百山祖国家公园内、外物种的科、属、种Jaccard相似性系数分别为0.50、0.45和0.12,表明2个区域物种组成差异较大。③与百山祖国家公园历史数据相比,本次调查新增6种,其中有3种仅分布于保护区外,包括保护价值极大的陈氏唇鳞苔Cheilolejeunea chenii。【结论】叶附生苔类植物在浙江省庆元县境内存在保护空缺,应尽早开展对中国其他地区叶附生苔类植物保护空缺研究。表1参28。[Objective]This study is aimed to understand whether there is a conservation gap of epiphyllous liverworts in the in-situ conservation of China.[Method]A systematic survey of epiphyllous liverworts in Baishanzu National Park and its surrounding habitats was carried out in Qingyuan County,Zhejiang Province.The diversity,distribution,species composition and similarity in and out of the reserve were analyzed and compared.[Result](1)A total of 25 species of epiphyllous liverworts belonging to 11 genera and 4 families were recorded,including Lejeuneaceae(21 species),Radulaceae(2 species),Metzgeriaceae(1 species)and Frullaniaceae(1 species).The dominant family in the area was Lejeuneaceae and the dominant genus was Cololejeunea.Cololejeunea longifolia and Leptolejeunea subacuta were common species in this area.(2)Among the 25 species of epiphyllous liverworts in 11 genera and 4 families,14 species belonging to 9 genera and 4 families were found in the park,and 14 species belonging to 7 genera and 2 families were found out of the park.However,the Jaccard similarity coefficients of families,genera and species in and out of the park were 0.50,0.45 and 0.12,respectively,indicating that the species composition of the two regions was quite different.(3)Compared with the historical data of Baishanzu National Park,there were 6 species newly recorded in this survey,of which 3 species were only distributed outside the park,including Cheilolejeunea chenii,a species with great protection value.[Conclusion]There is a conservation gap in the in-situ conservation of epiphyllous liverworts in Qingyuan County,Zhejiang Province.Therefore,research on the conservation gap of epiphyllous liverworts in other regions of China should be carried out as soon as possible.[Ch,1 tab.28 ref.]
