Riparian soils, together with vegetation, play a crucial role in supporting biodiversity and driving biogeochemical processes within river ecosystems. Conservation of riparian soils artificial planting are essential for ecosystem recovery following land degradation. Researchers focus on examining soil nutrients, microbial biomass, organic acid metabolism the interactions between plants along riverbanks. However, seasonal responses to plantations have been infrequently reported existing literature. This study investigates influence variations conditions growth artificially planted species zones Three Gorges Dam Reservoir (TGDR) China. The sampled include Cynodon dactylon, Hemarthria altissima, Salix matsudana. These provide valuable insight into properties zones, assessing across different seasons: T1 (spring), T2 (summer), T3 (autumn). results demonstrated significant changes matter, ammonium nitrogen, nitrate other indicators T3. Apart from invertase activity H. altissima soil, enzyme peaked during T1. Dominant bacteria were examined using high-throughput 16S rDNA sequencing, revealing that available belong 62 phyla 211 classes. Among most abundant Proteobacteria Actinobacteria, averaging over 60% all samples. Principal component analyses accounted 62.81% (T1), 50.57% (T2), 54.08% (T3) variation observed study, indicating predominantly influenced by phases, assuming factors remained constant. Pearson correlation analysis (p < 0.05) identified strong positive correlations physical three plant (r ≤ 0.94), as well negative bacterial communities -1.00). findings suggest selected well-suited cultivation zone TGDR. enhances our understanding dynamics environments, offering practical insights their management.
