Retrogressive succession alters soil conditions and microbial community dynamics in cold-region wetlands, yet its ecological implications remain understudied. This study explored the structure function of communities across three successional stages: swamp (SP), swamped meadow (SM), (MW). High-throughput 16S rRNA gene sequencing identified 2852 operational taxonomic units (OTUs), with 1682 shared among all stages (58.85%). Alpha diversity indices, including Shannon, Chao, ACE, Sobs, were significantly higher MW, Shannon index increasing by approximately 32% compared to SP, indicating enhanced richness evenness. In contrast, Simpson Coverage indices highest SP. Proteobacteria, Actinobacteriota, Acidobacteriota dominant phyla, showing distinct distributions stages. Beta analysis (PCoA NMDS) revealed clear separation communities. Soil organic carbon (SOC), pH, water content (SWC), cation exchange capacity (CEC), bulk density (BD) influenced composition distribution. Functional prediction using FAPROTAX BugBase indicated a shift from anaerobic metabolism, nitrogen fixation, cellulolysis SP aerobic chemoheterotrophy stress tolerance MW. These results demonstrate that adapt changing environments during retrogressive succession, highlighting their role ecosystem resilience wetlands.
