A Prliminary Study On Liverworts Of Mts. Taihang And Yanshan In Hebei

Mts. Taihang in the border areas between two provinces of Hebei and Shanxi, most of them in altitude are above 1200 m, which starting from Mts. Xishan of the north of Beijing and on the south of the Yellow River Mts. Wangwu. Mts. Yanshan located in the north of plains of Hopei, which is the east of White river valley, the west of Shanhaiguan, and the sorth of Bashang plateau. The geographical coordinates of latitude 39°40′-42°10′, and the longitude is 115°45′-119°50′.The specimens in this study are mainly collected from the northern Mts. Taihang and Mts Yanshan in Hebei. Through indoor specimens sorting and references consulting, and according to Bryophytes taxonomy system methods such as the morphology and anatomy, plant geography, etc, the author concluded the results as follows:1.80 species of liverworts identified in north of Mts.Taihang and Mts.Yanshan (including 2 subspecies and 6 varieties), belonging to 20 families,33 genera. Among them, containing a new record 1 genera, and 9 species newly recorded in Hebei.2. Confirming 5 dominant families(≥5 species), including 9 genera and 40 species, which respectively are in the total families, genera and species number of 21.74%,27.27%, 50.00%. There are 6 dominant genera (≥4 species), including 39 species, the propotion of total genera and species respectively is 18.18% and 48.75%. Through the study of dominant families and genera, the result shows that the temperate of these two moutains are with obvious temperate nature, and that the phenomenon is remarkable.3. The flora of liverworts in Mts. Taihang and Yashan contains 8 geographical elements and 9 distribution patterns. The main ingredient for the north temperate zone (47.50%), the east Asia component (16.50%) in the next place, and followed by peculiar rich endemic in China. The result clearly shows that the temperate is significant of these moutains, and slightly Asian colors.4. In addition,1tables,55 figers,41 regerences are provided.
