摘要
在野外调查采集和标本鉴定的基础上,首次报道了四川王朗国家级自然保护区的藓类植物134种(含1亚种、1变种),隶属87属,33科,其中四川省新纪录种9种,为石缝藓[Saelania glaucescens(Hedw.)Broth]、北地链齿藓[Desmatodon leucostoma(R.Brown)Berggr.]、卷边紫萼藓[Grimmia donnianaSm.]、木灵藓[Orthotrichum af-fineBrid.]、广口卷叶藓[Ulota eurystomaNog.]、小白齿藓[Leucodon pendulusLindb.]、拟扭叶藓[Trachypodopsisserrulata(P.Beauv.)Fleisch.]、多态嗜湿藓[Campyliadelphus protensus(Brid.)Kanda]、柔软明叶藓[Vesiculariaflaccida(Sull.&Lesq.)Iwats.]。优势科为丛藓科[Pottiaceae(9属)]、曲尾藓科[Dicranaceae(7属)]、羽藓科[Thuidiaceae]、塔藓科[Hylocomiaceae(均6属)];优势属为提灯藓属[Plagiomnium(6种)]、真藓属[Bryum(5种)]、曲尾藓属[Dicranum(5种)]。对王朗地区的藓类植物区系成分初步分析结果,主要为北温带成分(55种)和东亚成分(45种),分别占总种数的46.21%、37.82%。文内还分析比较了王朗自然保护区与川内及全国共11个地区藓类植物区系之间的关系。
Based on field investigation and identification the specimens collected,33 families,87 genera and 134 species（including 1 subspecie,1 variety） of mosses from Wanglang Nature Reserve in Sichuan Province of China are reported for the first time.Among them,nine species are new records for Sichuan.They are Saelania glaucescens（Hedw.） Broth.,Desmatodon leucostoma（R.Brown） Berggr.,Grimmia donniana Sm.,Orthotrichum affine Brid.,Ulota eurystoma Nog.,Leucodon pendulus Lindb.,Trachypodopsis serrulata（P.Beauv.）Fleisch.,Campyliadelphus protensus（Brid.） Kanda,and Vesicularia flaccida（Sull. Lesq.）Iwats..The comparison results showed that Pottiaceae,Dicranaceae,Thuidiaceae,Hylocomiaceae are the common dominant families and Plagiomnium,Bryum,Dicranum are the common dominant genera in the reserve.Concerning the elements of the mossflora of Wanglang Nature Reserve,North Temperate elements and East Asian elements are the most two important ones（46.21% and 37.82% of the total）.Comparison between the bryoflora of Wanglang Nature Reserve and those of the other 11 regions,the similarity coefficients of moss genera and species are also discussed.
