Abstract [Background] This paper explored the community structure and diversity of soil fungi under three sand-fixing plants in Hulun Buir Desert, clarified the dominant groups of soil fungi, and provides a scientific basis for determining the optimal sand fixation species for rebuilding degraded sandland ecosystems.[Method] Effects of Artemisia halodendron-, Caragana microphylla-, or Pinus sylvestris var. mongolica-dominated vegetation on fungal community structures and diversity in the Hulun Buir Desert were determined using field investigation and high-throughput 18SrRNA gene sequencing. [Results] The phyla Ascomycota accounted for more than 65% of the fungal sequences in the three vegetation. Additional dominant phyla including Zygomycota, Chytridiomycota, Basidiomycota, Cryptomycota and Glomeromycota were also in all soil sampling. The dominant classes of soil fungi were Dothideomycetes, Chytridiomycetes, Pezizomycetes, Sordariomycetes, Agaricomycetes, Eurotiomycetes and Glomeromycetes. The dominant genera of soil fungi were Talaromyces, Chaetomium, Boeremia, Paraphaeosphaeria, Cochliobolus, Mucor, Pseudogymnoascus, Fimicolochytrium and Suillus. There was no significant difference in soil fungi species among different vegetation, but the relative abundance of soil fungi varied. Compared with other vegetation, P. sylvestris var. mongolica exhibited a higher relative abundance of Pezizomycetes, Eurotiomycetes, Chaetomium and Talaromyces, which had the characteristics of promoting soil carbon cycle and phosphorus cycle. The activity values of phosphatase and catalase were significantly higher in P. sylvestris var. mongolica. Vegetation species were the main impact factors causing shifts in the soil fungal community. Soil organic carbon and available phosphorus were the main environmental factors to explain the structure of the soil fungal community. [Conclusions] The application of different vegetation in degraded lands alters the fungal community structure through changing their relative abundance. P. sylvestris var. mongolica was the most suitable species in fixing mobile dunes and improving soil fertility more than the three other species in Hulun Buir Desert.
