Abstract Human activities and regional land development have considerably contributed to the degradation of ecosystems growing contradiction between supply demand ecosystem services (ESs) in Jiangsu Province, China. However, few studies applied a comprehensive approach elucidate patterns evolutionary characteristics ESs over long periods. This study investigated spatial–temporal evolution supply, demand, supply–demand relationships six individual Province from 2000 2020. It revealed key drivers changes relationship (CESSD) using geo‐detector model geographically temporally weighted regression address shortcomings previous studies. The results showed that at provincial level, CESSD presented surplus while state tended be imbalanced. At 1‐km 2 grid scale, spatial heterogeneity was obvious, with zones primarily distributed Taihu Lake watershed, hilly areas, riverside zones, watershed Hongze Gaoyou Lake, eastern coastal zone, deficit were mainly clustered areas concentrated contiguous construction land. From 2020, area increased 626 3257 km degree gradually deepened, socioeconomic factors having greatest influence on CESSD. Our findings reveal balance/imbalance human society natural ecology highlight need for effective management ecosystems.

ABSTRACT As urbanization and industrialization advance, China faces increasingly severe ecological challenges. The Ecological Protection Redline (EPR) policy is a crucial tool for land use management protection but requires comprehensive risk assessment method to address ongoing This study integrated multiple factors with resilience theory establish “Hazard‐Exposure‐Vulnerability‐Damage‐Final Risk” framework, assessing the spatiotemporal dynamics risks of different EPR types in Qinghai Province over 20 years. Path analysis was further used reveal relationships between stages. Results show increasing hazards exposure Water Conservation (WC), Biodiversity Maintenance (BM) Land Desertification (LD) types, improved water conservation, stable biodiversity, controlled desertification vulnerability across regions. Integrated results downward trend WC type, BM type fluctuated improved, an initial increase followed by decrease LD type. revealed that damage WC‐type driven direct hazard impacts, BM‐type vulnerability, LD‐type indirect effects through exposure. emphasizes optimization policies reducing external disturbances enhancing ecosystem resilience, providing recommendations practical experience sustainable management.

ABSTRACT Protecting cultivated land in China is crucial for both food security and ecological sustainability. However, research on protection from the perspective of ecosystem services (CESs) remains limited, particularly regarding assessment CESs, complex trade‐offs between them, identification their driving forces to inform policy‐making. This study develops a multi‐dimensional evaluation framework assess eight analyze dynamics trade‐offs, identify CES bundles, examine influencing factors Yangtze River Economic Belt (YREB), China. Results indicate that grain production exhibited steady increase over past two decades, with slight decline after 2015. Water conservation related fluctuated, initially declining, peaking 2015, then decreasing again. In contrast, landscape aesthetics consistently declined, while habitat maintenance improved 2000 2010 but weakened thereafter. Five pairs CESs maintained stable whereas some synergies diminished time. Seven distinct bundles were identified, reflecting site‐specific conditions support multifunctional management. Key negative affecting most included temperature, precipitation, elevation, urbanization rate, rural residents' disposable income, population density, primary industry share, road network density positively influenced several CESs. enriches analytical through an service lens offers insights policies such as trinity system land, natural resource asset assessment, degradation prevention.
