The Yellow River Delta (YRD), a critical economic zone along China's eastern coast, also functions as vital ecological reserve in the lower River. Amidst rapid industrialization and urbanization, region has witnessed significant land use/cover changes (LUCC), impacting ecosystem services (ES) security patterns (ESP). Investigating LUCC's effects on ES ESP YRD is crucial for sustainable development. This study utilized PLUS model to simulate 2030 use scenarios, including natural development (NDS), (EDS), protection scenarios (EPS). Subsequently, InVEST circuit theory were applied assess under varying LUCC from 2010 2030. Findings indicate: (1) Notable 2030, marked by decreasing cropland increasing construction water bodies. (2) From 2020, improvements observed carbon storage, yield, soil retention, habitat quality, whereas 2020–2030 saw increases yield retention but declines quality storage. Among EPS showed superior performance all four ES. (3) Between sources, corridors, pinchpoints expanded, displaying spatial heterogeneity. scenario yielded most substantial pinchpoints, totaling 582.89 km2, 645.03 64.43 respectively. highlights importance of EPS, offering insightful scientific guidance YRD's

As China's largest cross-regional urban agglomerations, the middle reaches of Yangtze River agglomerations (MRYRUA) possess both significant societal carbon source volume and ecological sequestration capacity. Nevertheless, with uncontrolled expansion energy consumption activities industry migration from eastern coastal regions to inland cities, budget pattern territorial space is increasingly unbalanced in MRYRUA. To achieve low-carbon regulation, this study utilized land use data 31 cities within MRYRUA establish a "carbon source-carbon sink" quantification spatiotemporal exploration model, revealing spatial-temporal variation budgets 2005 2020. Furthermore, we developed balance indicator analysis system by employing offset rate (COR), productivity (CP), Gini coefficient, support coefficient (ESC), economic contribution (ECC), functional zoning was performed. Finally, using GM (1,1) derived for 2050 explored differentiated regulatory mechanisms under perspective. The results indicated that: (1) MRYRUA's have increased annually, displaying spatial distribution highest values central region, followed northwest, lowest southeast near water bodies. differentiation effects manifest as an east–west axial development trend, clustering demonstrating propensity outward dispersion northern hot spot radiation core. (2) COR has consistently remained below 10% decreased while CP shown yearly increase at accelerating rate. ESC ECC exhibit evident heterogeneity among cities. In response emission benefits carrying capacity reflected indicators, each city classified into zones, intensity control sink high-carbon optimization zones. (3) From 2020 2050, polarization trend continues intensify. Subsequently, established mechanism. This mechanism strengthens leading role zones green transition, moderately retains solid fixation capabilities, promotes transition research findings provide scientific basis formulating planning policies neutrality
