Study On The Bryoflora Jiufeng Mountain Natural Reserve

Jiufeng mountain is the Daqingshan National Natural Reserve，s coreare，located in the middle of Yin mountains;The total area is460squarekilometers;Known as " little Taishan"’s mountain peak elevation is2337.8meters.This with the East broad leaved forest consisting mainly of" primitiveforest island",to protect the adjacent areas of the ecological environment is ofgreat significance;Animal,plant resource variety, man-made destructionlittle,has very high scientific value.However, up to now,Jiufeng mountainNatural Reserve of bryological research is still at the eighty time Yang Chiholding et al stage, basically blank, therefore, urgent need in-depth study, theresults not only for the effective management of protected areas to provide thetheory basis, but also for Inner Mongolia and China to provide the basic datafor study on bryophytesThrough field sampling Jiufeng mountain Natural Reserve of bryophytespeciemens, and the sorting, identification and data analysis, informed:First,the district has34families,82generas,159species (includingvarieties and subspecies) of bryophytes; Includes11families,13generas,18species of liverworts;23families,69generas,141species of mosses.Second,the district advantage family including Pottiaceae (20generasand44species) and Hypnaceae (7generas and12species), the former44,accounting for29.45%of the total number, is the first dominant family;Bryaceae (4generas and10species) and Mniaceae(3generas and10species)two branch of the total species accounted for Jiufeng Mountain NaturalReserve moss is12.27%of the total species, the two section is relativelydominant families. Didymodon of Pottiaceae with10species, accounting for6.75%of the total number, is absolute advantage bryophytes of Jiufengmountain Nature Reserve.The district has only specie of section containing22,accounts for the numerous number64.71%; With only specie of genera containing44, which account for54.22%of total genera. Single genera offamily with only1, representing the number of superfamilies number2.94%;Single specie of genera4, which account for6.02%of total genera.Third, this study found except" bryophyte flora of Inner Mongolia"recorded in Jiufeng mountain Natural Reserve of moss plants of18families,28generas,30species,16families new record,54generas newrecord,and128species new record.Fourth,the area of moss flora has40Cosmopolitan, accounting for25.15%of the total number;77North temperate elements accounting for47.24%of the total number of6;East Asian and North American elements,thetotal number of3.68%;7Old World temperate elements,corresponding to5.52%of the total;7Temperate Asian elements,accounting for4.29%of thetotal number;14East Asian elements, accounting for8.59%of the totalnumber;6Elements Endemic to China, accounting for3.68%of the totalnumber;2Endemic to Inner Mongolia elements,accounting for1.23%of thetotal number.Fifth, Jiufeng mountain and Helan mountain flora of bryophytes are mostclosely related,and Qilaotu mountain,Guancen mountain and ChangbaiMountain is close;The eastern Tianshan Mountains mainly has compositionelements,Xitianmu Mountain for subtropical elements, the area and the twomountain distantly related.Seven mountains’ family,genera,specie,the numberof similar tendency;Changbai Mountain’s most abundant, followed by theWest Tianmu Mountain,the Qilaotu mountain,the Eastern TianshanMountain,the Guancen mountain and the Jiufeng mountain,the Helanmountain has the least.The area of eight habitats of species richness from bigto small is as follows:wet soil native,the birch forest,dry soil native,wet stonenative,dry stone native,spruce forest,wood and aquatic;Birch forest in the areaof moss plants diversity of critical habitat.Habitat is different,the species isalso different:spruce and birch forest dominant species are like wet and widespread species,dry soil native and stone native’s advantage specie is droughttolerant species,wet soil native and stone native’s advantage specie are like wet type,aquatic habitat advantages are like wet type,wood habitat the speciesrichness and the air humidity is closely relation.Eight kinds of habitats in theShannon-Wiener index from big to small is as follows:the birch forest,drystone native,wet soil native,wood,dry soil native,spruce forest,aquatic and wetstone native.Eight kinds of habitats in the Pielous evenness index ofsimilarity,namely individual uniformity nearly.Seventh,the area of the red list of endangered bryophytes has7species:includes1critically endangered(CR),2endangered spcies(EN),4easyendangered (VU).
