5. Conclusion
N addition in temperate Korean pine plantation ecosystems altered AM
fungal community structure, reduced AM fungal and herb diversity,
decreased soil pH, increased inorganic N concentration, and decreased
soil fast-acting phosphorus content. We suggested that the N application
first changed the soil characteristics and then changed the composition
and diversity of the soil AM fungal, and the changes in the AM fungal
community in turn affect the distribution of soil aggregates, and the
above-mentioned factors (biotic and abiotic) in the subsurface part
together affect the plant community and diversity. Considering the
importance of AM fungi in the ecosystem, future research should explore
the pathways by which AM fungi regulate the ecological functions under N
additional conditions to improve our understanding of the ecological
functions of AM communities under global environmental change
conditions.
