Résumé partiel
Table Mountain is the edge of Helan Mountain.It is a central area about biodiversity.It is located in Wuhai City and belongs to the West Ordos Nature Reserve.It connects the Yinshan Mountains with the Helan Mountains.Langshan is the westernmost section of the Yinshan Mountains.Both Table Mountain and Langshan Mountain are mountainous areas in Western Inner Mongolia.Both mountainous areas are typical grassland desert areas.Few people have studied the moss in the two mountains.By studying the species diversity,floristic geographic composition and anatomical structure of bryophytes in Table Mountain and Langshan Mountain,we can know the following points :(1)There are 60 species(including varieties and subspecies)belonging to 25 genera and 25 genera in 10 families in Table Mountain(including Gander Mountain).Among them,2 families,2 genera and 3 bryophytes belong to 3 genera,8 families,23 genera and 57 species.There are 3 dominant families,including 18 genera and 46 species,which account for 76.66% of the total bryophytes species in Table Mountain.The bryophytes belong to absolute dominant families,accounting for the total bryophytes.53.33%.There are two dominant genera,i.e.Opposite Dental Moss and Eucommia,which account for 35% of the total bryophyte species in Table Mountain.There are only four families with one species,14 genera with only one species,and more single families and single genera.(2)There are 38 species(including varieties and subspecies)of 23 genera and 23 genera in 11 families in Langshan Mountain.Among them,2 families,3 genera and 3 bryophytes,9 families,20 genera and 35 species of bryophytes,and 2 dominant families,respectively,consist of 23 species in 10 genera,accounting for 60.53% of the total bryophytes species in Langshan Mountain.The dominant genera are only one,accounting for 50% of the total bryophytes species in Langshan Mountain.There are 4 families with only one species,15 genera with only one species,and more single families and single genera.(3)There are 29 species of bryophytes in Table Mountain and Langshan Mountain,and their floristic and geographical components are very similar
