| 英文摘要 | High rodent density is a critical factor hindering the restoration of degraded grassland ecosystems in Sanjiangyuan National Park. The establishment of artificial perches serves as a mechanism to facilitate the return and breeding of raptors, providing a biological control method for rodent populations. However, a systematic understanding of the positive ecological impacts of artificial perches on grassland restoration remains lacking. This study focuses on the degraded alpine grassland ecosystem of Sanjiangyuan National Park, where artificial perches have been established for four years. Through investigations of rodent burrow characteristics, plant community attributes, soil physicochemical properties and soil microbial community structure (16S, ITS), we explore the effects of artificial perches on various ecological components. Additionally, the ecological benefits of artificial perches were evaluated in terms of plant community stability and soil microbial network stability. Our findings indicate that artificial perches significantly reduced both the number and rate of effective rodent burrows, while significantly enhancing plant community height, coverage, biomass and species richness. Although artificial perches did not significantly affect plant community stability, they were found to improve the stability of soil microbial networks. The impact of artificial perches on the beta diversity of bacterial and fungal communities suggests that they indirectly affect microbial community structure through the modulation of rodent behavior and changes in plant biomass. Structural equation modeling results indicate that raptor perch significantly enhances plant community species richness, while plant community species richness has a significant positive influence on microbial network stability. Microbial network stability was significantly correlated with bacterial and fungal community diversity, as well as with fungal community composition. Notably, higher fungal diversity was positively correlated with network stability, while higher bacterial diversity had a negative impact. These results highlight that, in Sanjiangyuan National Park, artificial perches not only regulate rodent activity but also promote positive ecological effects across multiple components, particularly by enhancing the stability of soil microbial networks. This approach offers distinct advantages over other restoration strategies for degraded grasslands. |
