This study explored the dynamics of bacterial community composition, response to environmental factors, and co-occurrence network models across different habitats Wuliangsuhai Lake during glacial period. Water quality analysis high-throughput sequencing were performed at 14 monitoring sites within lake. Additionally, a between two operational taxonomic unit (OTU)-OTUs was established. The results indicated significant differences in water indices, namely total nitrogen (TN), chemical oxygen demand (COD), dissolved solids (TDS), salinity (SAL), chlorophyll-a (Chl.a), electrical conductivity (EC), ice bodies subglacial water. Although there no α diversity various media, substantial observed β diversity. VIF RDA analyses revealed that lake factors significantly affected microbial structure COD TDS had highest explanation for composition change. Network demonstrated competition dominated with higher complexity stability body bacteria exhibited more reciprocal relationships weaker resistance external disturbances. modular environment, g_Flavobacterium, f_Arcobacteraceae, g_Sphingobacteriaceae being main keystone species. Investigating habitat heterogeneity communities identifying major groups key species using molecular ecological their topological effects can provide theoretical foundation assessing structural ecosystems cold regions.
