Marine bacterioplankton perform a very important role in the cycles of carbon, nitrogen, phosphorus, and other elements coastal waters. The impacts environmental factors on bacterial community structure are dynamic ongoing. This study investigated spatiotemporal distributions their influences communities waters around Changli Gold Coast National Nature Reserve northern China. results demonstrate significant temporal variability carbon spring summer, influenced by natural anthropogenic activities. In spring, increased biological activity, particularly phytoplankton growth, may elevate TOC POC levels near river estuaries, while microbial decomposition likely stabilized concentrations. seasonal variation was obvious. Bacteroidetes were enriched samples Cyanobacteriota proliferated summer. dominated genera including Planktomarina, an unclassified NS5_marine_group (belonging to Flavobacteriaceae), OM43_clade (Methylophilaceae), showed positive correlation with salinity, TDP, TOC, POP, DO levels, Synechococcus_CC9902 (Synechococcus), PeM15_unclassified (Actinobacteria), HIMB11 (Rhodobacteraceae), which all dominate summer samples, significantly positively correlated TN, TDN, temperature, ammonium levels. particular, increase human activities inputs greatly improves nutrient promotes propagation photosynthetic microorganisms. These indicate that physical conditions affected changes activities, have effects bacterioplankton. highlights importance ongoing monitoring estuarine areas, especially protected areas like Reserve, manage eutrophication risks maintain ecological balance.
