Abstract:

To reveal the differences in ecosystem multifunctionality and microbial diversity among different land use patterns and provide scientific basis for farmland soil management and sustainable development,five types of farmland soils(orchard,cornfield,soybean field,greenhouse,and abandoned land)were selected as research objects. Soil physicochemical properties,enzyme activities,and microbial diversity were analyzed,and the differences in ecosystem multifunctionality and microbial diversity among different land use patterns were compared. The results showed that there were significant (p0.05)differences in soil ecosystem multifunctionality indicators among different land use patterns. Correlation analysis revealed that soil pH value,available nitrogen content,total nitrogen content,total phosphorus content,available phosphorus content,organic matter content,and the activities of β-glucosidase,N-acetyl-β-glucosaminidase,cellulase,polyphenol oxidase,and peroxidase were significantly correlated with ecosystem multifunctionality. Analysis of variance indicated that orchard soil had the highest ecosystem multifunctionality,whereas cornfield soil almost lost its ecosystem multifunctionality under the 75% threshold. High-throughput sequencing results showed that orchard soil had the highest bacterial diversity,and bacterial communities had a more significant impact on soil ecosystem multifunctionality than fungal communities in farmland soil ecosystems. In conclusion,protecting farmland soil bacterial diversity should be the core strategy for improving farmland soil ecosystem multifunctionality. The high ecosystem multifunctionality of orchard soil verifies the positive feedback mechanism of microbial diversity on ecosystem function,making it the most recommended land use pattern.
