The Wenchuan earthquake, an unexpected magnitude 8.0 mega-earthquake that struck on 12 May 2008, significantly changed land cover (LC), particularly affecting vegetation and rock cover. However, the long-term effects of LC changes ecosystem services (ESs) remain unclear in earthquake-affected regions, especially across different spatial scales. This study, focusing County, employs a multi-model framework integrates fractional coverage (FVC), exposure rate (FR), (ESs), combining correlation analysis, geographically weighted regression (GWR), Self-organizing map (SOM) clustering, XGBoost-SHAP model, to analyze spatiotemporal dynamics, interrelationships, driving mechanisms (LC) ESs before after earthquake. Results show that: (1) From 2000 2020, FVC FR fluctuated markedly under earthquake influence, with slight declines habitat quality (HQ) carbon storage (CS) notable improvements soil conservation (SC) water yield (WY). (2) With increasing elevation, FVC–CS–SC group exhibited downward trend synergy, while FR–HQ–WY increased also showed synergy; trade-offs synergies became more pronounced at larger scales, displaying strong heterogeneity. (3) Elevation (explaining 10–60% variance) was main driver for ESs, use, slope, human activities, climate, geological conditions impacting individual indicators. At same time, existing hazard points are mainly concentrated along both sides river valleys, which may be associated intensified human–land conflicts. These findings offer valuable insights into ecological restoration sustainable development regions.

Healthy watershed environments are essential for socioeconomic sustainability. The long-term monitoring and assessment of ecological provide a timely accurate understanding ecosystem dynamics, informing industry policy adjustments. This study focused on the upper-middle Fen River Basin (UMFRB) in eastern China’s Loess Plateau analyzed spatial temporal characteristics eco-quality from 2000 to 2023 by calculating remote sensing index (RSEI) via Google Earth Engine (GEE) platform. In addition, this also explored trends future consistency RSEI, as well impacts natural anthropogenic factors RSEI variations. findings revealed that (1) average value increased 0.51 0.57 over past 24 years, reflecting an overall improvement eco-quality, although urban centers Taiyuan exhibited localized degradation. (2) Hurst was 0.468, indicating anti-consistency, with most regions showing decline or exhibiting stochastic fluctuations. (3) Elevation, temperature, precipitation, slope, land use intensity significantly correlated quality. Natural dominate densely vegetated regions, whereas populated plains. These results valuable guidance formulating targeted restoration measures, protection policies, engineering solutions.
