Aggregation and co-occurrence patterns of microbial communities are the key scientific issues in lake ecology. To explore mechanisms ecological assembly community succession this unique habitat, 16 samples were collected from eight sites Wuliangsuhai Lake. Second-generation DNA sequencing was applied to reveal spatial dynamics bacterial structure distribution across two environmental media nutrient-rich shallow grassland elucidate characteristics network. This study also examined effects filtering biological interactions on formation maintenance composition diversity. The results highlight habitat heterogeneity composition, with no discernible latitudinal diversity patterns. causal analysis identified electrical conductivity, pH, total nitrogen, phosphorus as primary factors driving changes water sediment grass-type lakes, TN being driver. CL500-3 a pollution-tolerant species aquatic environments. g__norank_f_Verrucomicrobiaceae exhibited significant distance decay pattern, higher turnover rate than sediment. Co-occurrence network revealed greater complexity stability communities, three potential keystone species, water. neutral null model indicated that more susceptible dispersal limitation, whereas complex increased role deterministic processes construction. proposed division plant regions freshwater lakes demonstrated different types, contributing comprehensive understanding shallow-water structure.
