Riparian zones maintain biodiversity, cyclic nutrients, and regulate water quality. However, their stability is increasingly threatened by human activities such as dam construction climate variability. This study focuses on the riparian of Three Gorges Dam Reservoir (TGDR), a region marked fluctuating levels subtropical southeast monsoon climate. We investigated seasonal vegetation-specific dynamics soil properties microbial communities in dominated artificially remediated plants (ARPs) TGDR. The selected ARP species included herbaceous Cynodon dactylon (CD) Hemarthria altissima (HA), known for capacity rapid stabilization, tree Salix matsudana (SM) Taxodium distichum (TD), which enhance nutrient cycling through litter inputs root exudates. These were evaluated across spring (T1), summer (T2), autumn (T3). Our analysis 360 samples led to generation high-quality sequences that provided insights into diversity. Principal component identified organic matter, ammonium nitrogen, total nitrogen main contributors property variance, explaining 53.68% T1, 51.52% T2, 56.37% T3 variance (p < 0.01). Correlation highlighted positive relationship between pH Nitrospirae (r = 0.603) Proteobacteria 0.558). Enzyme activity varied season, with acid phosphatase peaking invertase highest T1. also made functional predictions pathways pertinent metabolism, genetic information processing, environmental signal transduction. There shifts metabolic pathways, an increase carbohydrate metabolism via TD. In addition, there was rise amino CD. assessment diversity uncovered 68 bacterial phyla, Acidobacteria emerging dominant taxa. results indicate ARPs positively influence health, cycling, overall ecosystem integrity. findings hold significant implications restoration regions experiencing changes.
