黄山苔类植物区系研究

Studies on Liverwort Flora in Huangshan Mountain

摘要: 黄山位于安徽省南部,根据调查和统计,共有苔类植物28科、48属、117种(包括亚种和变种)。该区苔类植物的优势科为细鳞苔科Lejeuneaceae、羽苔科Plagiochilaceae、光萼苔科Porellaceae、耳叶苔科Frullaniaceae;优势属为耳叶苔属Frullania、羽苔属Plagiochila、光萼苔属Porella、鞭苔属Bazzania、细鳞苔属Lejeunea。区系成分以热带成分和东亚成分为主,分别占到40%和39.09%,北温带成分占有一定的比例为20%。无毛拳叶苔Nowellia aciliata(P.C.Chen&P.C.Wu)Mizut.和新绒苔Neotrichocolea bissetii(Mitt.)S.Hatt被列入我国濒危苔藓植物红色名录。

Abstract: According to investigation and statistics,there are 117 liverworts belonging to 48 genera in 28 families in Huangshan Mt.,which located in the south of Anhui province.The predominant families are Lejeuneaceae,Plagiochilaceae,Porellaceae and Frullaniaceae;predominant genera are Frullania,Plagiochila,Porella,Bazzania,Lejeunea.Based on the analysis of geographic elements of species,the result shows the Tropical elements and the East Asiatic element are dominant,accounting for about 40% and 39.09% of the whole liverwort flora respectively,and the proportion of the temperate element is 20%.Nowellia aciliata(P.C.Chen & P.C.Wu)Mizut.and Neotrichocolea bissetii(Mitt.)S.Hatt.were inclu-ded in the red list of Chinese endangered bryophytes.
