About 35% of grassland in the Sanjiangyuan area of China has degraded into black-soil mountain, and artificial grassland has been used to combat this issue.
The study focused on mixed-sown artificial alpine grassland and compared it to degraded black-soil mountain grassland and natural alpine grassland, analyzing the community structure of soil bacteria and fungi.
Results showed that planting artificial grasslands significantly improved soil carbon and nitrogen levels, altered microbial community compositions, and indicated that bacteria play a key role in nutrient cycling.
