Taebaek Mountain Bryophytes. Study

Taibaishan Nature Reserve lies in the middle part of QinlingMts , between 107°41'23?-107°51'40?E and 33°49'31?-34°08'11?. The bryophytes are abundance in this area, Taibaishan Nature Reserve lies in the transitional belt between temperate zone and subtropical zone, Through the research, it can supply basic information for bryophytes research in China.In this paper, the bryophytes speciments in Taibaishan Nature Reserve is systematically studied and the conclusion is that There are about 82 species (including 6 varieties, 2 forma and 1 subspecies) of Hepaticae belonging to 29 genera and 22 families and there are about 259 species (including 8 varieties, 1 forma and 1 subspecies) of Music belonging to 114 genera and 40 families.In these bryophytes , 2 genus and 5 species are newly reported in Qinling moutain . As to geographical elements, North temperate elements are dominance (52.41% of the total elements) , and East-Asian elements are at the second place (22.51% of the total elements);and tropical elements take a considerable part (5.15% of the total elements). Single species in one genus and single genus in one family are rich. It shows that the composition of Bryophytes in this area is relatively simple and the extent of differentiation is not high.In order to know more about the bryoflora in this region and its relationship to the adjacent or related areas including Foping Nature Reserve, Jinfu Moutain, Shennongjia Moutain, Qilian Moutain, Xiaowutai Moutain , the author compared the species abundance , the generic similarity coefficient , the phytogeographical elements, and used ordination method .The conclusion, based on the above research, are as follow: it has more relationship with Foping Nature Reserve and Shennongjia Moutain, less with Qilian Moutains, Xiaowutai Moutain and Jinfu Moutain. Taibaishan Nature Reserve lies in the transitional belt temperate zone and subtropicalzone, Xiaowutai Moutain has the same condition that North temperate elements are dominance and East-Asian elements are at the second place, it is evidence to the opinion that there is one of the migrate routes from the Himalayas through QinlingMts to the northeast of China.
