ABSTRACT Ecosystem service quality is closely linked to human well‐being, and sustainable provision of ecosystem essential for ensuring regional ecological security achieving sustainability goals. An innovative valuation framework introduced that combines land use/cover change (LUCC) analysis, supply demand matrices Gini coefficient calculations assess the services (ES‐S ES‐D). Unlike traditional static methods, this approach captures intricate spatial temporal mismatches, offering new insights into impacts LUCC on ES balance within development goals (SDGs). Taking Three Gorges Reservoir Area (TGRA) as a case study, findings indicate significant decrease in cultivated land, accompanied by expansion forest built‐up area, driven farmland‐to‐forest policies urbanization. These shifts have improved provisioning supporting but also intensified disparities, particularly Chongqing, where outpaces supply. Furthermore, altered capacity ecosystems TGRA provide services, such soil retention water regulation, thereby progress toward SDGs related sustainability. However, imbalances cultural persist, highlighting need targeted management strategies optimize support This study underscores importance ongoing ES‐S ES‐D assessments inform ecologically sensitive areas like TGRA.

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.
