Soil Fungal Community Structure under the Canopy of Alpine Trees and Shrubs
To explore the differences in soil fungal community structure under alpine forest trees and shrubs,this study selected three plots of tree forest and three plots of shrub forest with different dominant species in Maixiu Forest Farm,Huangnan Prefecture,Qinghai Province.Soil samples from 0-10cm depth were collected and analyzed for fungal composition,abundance,and diversity using high-throughput sequencing.The results showed that soil fungi under shrub canopies had significantly higher abundance at all taxonomic levels compared to those under tree canopies,and there were significant differences in community structure(P＜0.05).At the phylum level,Ascomycota was the dominant in both tree and shrub soils,but Basidiomycota was more abundant in tree soils,while Ascomycota was more dominant in shrub soils.At the genus level,Chlorophyllum and Fibulorhizoctonia were more abundant in tree soils,while Lophiostoma,Volutella,Herpotrichiellaceae,and Neonectria were more abundant in shrub soils.The differences in fungal community structure and diversity between tree and shrub soils reflect their adaptations to different environments.This study provides data to better understand the distribution of soil fungi under alpine tree and shrub forests and their responses to habitat conditions.
