Soil microorganisms provide valuable ecosystem services, such as nutrient cycling, soil remediation, and biotic and abiotic stress resistance. There is increasing interest in exploring total belowground biodiversity across ecological scales to understand better how different ecological aspects, such as stand density, soil properties, soil depth, and plant growth parameters, influence belowground communities. In various environments, microbial components of belowground communities, such as soil fungi, respond differently to soil features; however, little is known about their response to standing density and vertical soil profiles in a Chinese fir monoculture plantation. This research examined the assemblage of soil fungal communities in different density stands (high, intermediate, and low) and soil depth profiles (0–20 cm and 20–40 cm). This research also looked into the relationship between soil fungi and tree canopy characteristics (mean tilt angle of the leaf (MTA), leaf area index (LAI), and canopy openness index (DIFN)), and general growth parameters, such as diameter, height, and biomass. The results showed that low-density stand soil had higher fungal alpha diversity than intermediate- and high-density stand soils. Ascomycota, Basidiomycota, Mucromycota, and Mortierellomycota were the most common phyla of the soil fungal communities, in that order. Saitozyma, Penicillium, Umbelopsis, and Talaromyces were the most abundant fungal genera. Stand density composition was the dominant factor in changing fungal community structure compared to soil properties and soil depth profiles. The most significant soil elements in soil fungal community alterations were macronutrients. In addition, the canopy openness index and fungal c​o​m​

There is increasing interest in exploring total belowgroundbiodiversity across ecological scales to understand better how different ecological aspects, such as standdensity, soil properties, soil depth, and plant growth parameters, influence belowground communities. Invarious environments, microbial components of belowground communities, such as soil fungi, responddifferently to soil features; however, little is known about their response to standing density and verticalsoil profiles in a Chinese fir monoculture plantation. This research examined the assemblage of soil fungalcommunities in different density stands (high, intermediate, and low) and soil depth profiles (0–20 cm and20–40 cm). This research also looked into the relationship between soil fungi and tree canopy characteristics(mean tilt angle of the leaf (MTA), leaf area index (LAI), and canopy openness index (DIFN)), and generalgrowth parameters, such as diameter, height, and biomass. The results showed that low-density stand soilhad higher fungal alpha diversity than intermediate- and high-density stand soils. Ascomycota, Basidiomy-cota, Mucromycota, and Mortierellomycota were the most common phyla of the soil fungal communities, inthat order. Saitozyma, Penicillium, Umbelopsis, and Talaromyces were the most abundant fungal genera. Standdensity composition was the dominant factor in changing fungal community structure compared to soilproperties and soil depth profiles. The most significant soil elements in soil fungal community alterationswere macronutrients. In addition, the canopy openness index and fungal community structure have apositive association in the low-density stand. Soil biota is a nutrient cycling driver that can promote betterplant growth in forest ecosystems by supporting nutrient cycling. Hence, this research will be criticalin understanding soil fungal dynamics, improving stand growth and productivity, and improving soilquality in intensively managed Chinese fir plantations.
