Abstract: In this paper, the species diversity and distribution of ground bryophytes community under 10 vegetation types in Hunshandake Sandy Land were investigated. The results were as follows:(1) In total,115 species bryophytes (in 23 families and 54 genera) were found in this area. Of these, 9 species (in 6 families and 7 genera) were liverworts, 106 species (including varieties, in 17 families and 47 genera)were mosses, and all the bryophytes consisted of 4 kinds of growth forms of Cormus hepaticae (4 species), Thallus hepaticae (5 species), Acrocarpri-muscorum (63 species) and Pleurocarpi-muscorum (43 species). In addition, Pottiaceae, Bryaceae, Amblystegiaceae, Brachytheciaceae, Bryum, Brachythecium, Campylium et al in this area were dominant, North Temperate elements was the most abundant in 10 kinds of floristic geographical elements types, and Betula platyphylla forest, wetland, Picea mongolica forest and Sabina vulgaris shrub etc presented higher species number. With the increase of water content, the number of species and the types of growth form increased, and the individuals of dominant species became larger. (2)Shannon-wiener index had the same changing trend with Patrick richness index, Simpson dominance index showed the opposite trend with the above two indexes, and soil moisture and air humidity are significantly correlated with species diversity and richness index. (3)Except for Picea mongolica forest with Sabina vulgaris shrub and Betula platyphylla forest, most species similarity coefficient between habitats was low.
