Abstract: To understand the community diversity differences of fungi in the rhizosphere soil of Zanthoxylum nitidum(Roxb.)DC in different regions,the rhizosphere soils of Z. nitidum in 6 different regions were studied. The ITS1-2 of fungi in soil samples was sequenced on the high-throughput platform. The community diversity differences of fungi in the rhizosphere soil were analyzed by contrast,and the effect of environmental factors on fungal community was discussed combined redundancy analysis. Research showed that the community diversity of fungi in 6 regions was rich,while there were significant differences in fungal community structure and species richness among the samples. Ascomycota,unclassified,Basidiomycota,Mortierellomycota and Rozelomycota were common. The dominant community composition of each sample varied,but the dominance of Ascomycete was significant. The order of fungal community diversity from high to low was as B3> A3> A2> B2> B1> A1. Environmental factors such as soil pH,organic matter content,soil clay,soil sand,and soil powder(sand)grains all can affect the community composition and species abundance of fungi in the samples,but the influence degree of environmental factors on each sample differed.

Key words: Zanthoxylum nitidum(Roxb.)DC, fungi in the rhizosphere soil, high-throughput sequencing, community diversity
