【Objective】To study soil microbial diversity under different vegetation of Gongliu wild fruit forest. 【Methods】Four different types of forest land with similar environmental conditions, namely Malus sieversii dominant forest, Armeniaca vulgaris dominant forest, multi-species symbiotic forest and forest grassland, were selected as sample sites. The soil physical and chemical properties of the four sample sites were collected and determined. Illumina-MiSeq high-throughput sequencing technology was used to investigate the soil microbial diversity and community structure of the four sample sites.【Results】(1) There was no significant difference in total nitrogen, total potassium, organic carbon and easily oxidized organic carbon in the four soils, and total phosphorus content in the symbiotic forest of multiple tree species was significantly higher than that in the other plots. (2) The OTU number of bacteria in the four soil species was significantly higher than that of fungi, and the abundance of bacteria and fungi in the soil in the dominant forest of Armeniaca vulgaris was the highest, while the abundance of bacteria and fungi in the soil of grassland was the lowest. The soil bacteria in the dominant forest of Malus sieversii identified a total of 30 phylums, 76 phylums, 135 orders, 185 families and 233 genera, and the soil fungi identified a total of 7 phylums, 20 phylums, 40 orders, 70 families and 90 genera; the soil bacteria in the dominant forest of Armeniaca vulgaris identified a total of 31 phylums, 78 phylums, 141 orders, 183 families and 220 genera, and the soil fungi identified a total of 8 phylums, 17 phylums, 35 orders, 69 families and 94 genera; soil bacteria in the symbiotic forest of multiple species were identified as A total of 221 genera of soil bacteria and 7 genera of soil fungi were identified in 29 phylums, 75 phylums, 137 orders, 179 families, and 7 phylums, 15 orders, 31 families, 53 families and 72 genera; a total of 201 genera of soil bacteria were identified in 28 phylums, 72 phylums, 126 orders, 162 families, and 5 phylums, 13 orders, 35 families, 61 families and 84 genera of soil fungi were identified in soil of the grassland in the forest. (3) In the bacterial community at the phyla classification level, the dominant bacteria were Actinomycota, Acidobacteria and Proteobacteria, while in the fungal community, the dominant bacteria were ascomycetes, mortieromycota and basidiomycota. At the genus level, the dominant bacteria genera are RB41 and Rokubacteriales, and the dominant fungi genera are Humicola, Mortierella and Linnemannia. 【Conclusion】There were differences in the diversity of soil bacterial communities under different vegetation in Gongliu wild fruit forest. The soil microbial species of forest land was the most abundant, while the soil microbial species of grassland was relatively poor.
