Investigation on Bryophyte Resource in Qinyang Nature Reserve in Dushan County of Guizhou Province

To enrich the bryophyte resource in Guizhou Province and provide the theoretical basis for this region to protect the bryophyte biodiversity,407 bryophyte specimens from Qinyang Nature Reserve were collected and carefully identified.It was found that there were 204 species(including subspecies and variation) which belonged to 81 genera in 38 families.And five of them were newly recorded in Guizhou.According to the checklist,There were ten dominant families(Porellaceae,Frullaniaceae,Lejeuneaceae,Marchantiaceae,Pottiaceae,Thuidiaceae,Hypnaceae,Meteoriaceae,Neckeraceae and Brachytheciaceae) and nine dominant genera(Porella,Frullania,Lejeunea,Marchantia,Thuidium,Plagiomnium,Brachythecium,Fissidens and Fissidens).The geographical distribution of various families and genera showed that the bryophytes in Qinyang Nature Reserve not only had temperate components,but also tropic and subtropical components.The bryophyte were all distributed on the centre transition zone from temperate zone to tropic zone no matter at which level of dominant families,genera or species.
