Abstract Background Minqin is suffering from a serious desertification, whereas the knowledge about its bacterial community limited. Herein, based on Nitraria tangutorum and Haloxylon ammodendron Minqin, diversities in fixed sandy land, semi-fixed land shifting were investigated by combining with culture-dependent culture-independent methods. Results stressed high salinity poor nutrition an oligotrophic environment. Bacterial was shaped primarily presence of host plants, type plant had no marked effect those, which displayed better survival rhizospheres N. H. . The dominant groups at phyla level Actinobacteria, Firmicutes, Proteobacteria, Bacteroidetes, Planctomycetes, Chloroflexi, Acidobacteria Candidate_division_TM7. abundance Firmicutes ability desiccation-tolerance significantly higher harsh environment, Bacteroidetes mainly distributed areas nutrient content. abundances Proteobacteria relatively , more plant-growth promoting rhizobacteria. A large number Actinobacteria detected, most abundant genus Streptomyces physicochemical factors related to diversity distribution comprehensively analyzed, such as pH, electrical conductivity, soil organic matter, C/N sand, results indicated that suitable for growth should be one important sand-fixing plants Minqin. Conclusions different types lands systematically approaches, has great significance maintaining/restoring biological diversity.
