Environmental managers have sought to optimize landscape structure maintain regional ecosystem health (EH). However, we still lack a full understanding of the effects changing on EH, especially in terms shorter time scales (e.g., monthly or seasonal scales) and spatial heterogeneity. To address this gap, study used vigor-organization-resilience-services (VORS) model assess annual variation EH Loess Plateau (LP) during 2000–2015, then applied geographically weighted regression (GWR) investigate different aspects (i.e., composition configuration) change over time. Our results showed that level LP from 2000 2015 displayed temporal non-stationarity at scales, pattern decreasing southeast northwest. The had obvious heterogeneity, depending local configuration. In general, configuration exerted greater impact than apart Shannon's diversity index percentage forestland area, but intensity direction higher temporally instability therefore should receive more attention. Furthermore, regulation dominant patch size, connectivity forest spacing is optimal choice for management. suggest responses changes vary by place, integrating characteristics can help decision-makers make precise arrangements adjustments keep negative ecological impacts within reasonable limits.

During the rapid urbanization phase, trade-off between ecosystem services is most severe and also effective stage to implement ecological management. Exploring natural—social driving mechanisms for trade-offs contributes coordinated development of social economy nature. Taking typical mountainous city (Yibin) that currently in phase ecologically fragile as an example, utilizing a combination difference comparison, trade-off–synergy index (TSI), optimal-parameter-based geographical detector model (OPGD), multi-scale geographically weighted regression (MGWR), we spatially assess nature intensity ES relationships explore its social–natural mechanisms. Our findings reveal following: (1) Varied geospatial patterns four ESs—habitat quality (HQ), carbon storage (CS), soil conservation (SC), water yield (WY)—with greatest fluctuations WY. (2) Significant changes over time, showing predominant positive synergies WY-HQ, WY-SC, HQ-CS, negative HQ SC, WY-CS SC-CS. (3) Distinct, time-varying factors different relationships: climate topography WY, vegetation CS, economic HQ, SC. Rapid has diminished role natural factors. (4) The coefficients local various factors, based on which targeted recommendations can be proposed.
