To evaluate the potential differences in plankton diversity and stability within freshwater lake reservoir ecosystems, this study employed eDNA metabarcoding to analyze diversity, assembly mechanisms, stability, environmental drivers of communities natural water (Y region) artificial (M at Liupanshui Minghu National Wetland Park, Guizhou Province, China. The revealed notable regional variations mechanisms. Specifically, Shannon, Simpson, Pielou's evenness indices were higher M region, suggesting a more complex species composition compared Y region. Analysis community mechanisms indicated that both regions influenced by combination stochastic deterministic processes, with processes serving as dominant driver. Through LEfSe analysis, Random Forest predictions, molecular ecological network evaluations, certain OTUs identified "dual-characteristic" consistently highlighted. These may play critical role shaping contributing stability. Environmental further clarified these differences. Redundancy analysis (RDA) demonstrated TDS was primary factor driving key zooplankton species, while EC DO significant factors influencing distribution phytoplankton species. Stability assessments, which combined coefficient variation population density, This indicates system has greater resistance disturbances findings provide fundamental support for assessing health aquatic well effective monitoring biodiversity conservation ecosystems.
