Rapid urbanization in China's urban agglomerations has severely disrupted the relationship between supply and demand for ecosystem services (ESs). Exploring spatial temporal variation characteristics of ESs balance its driving mechanisms is crucial high-quality development agglomerations. However, few studies have explored pattern at multiple scales agglomerations, which constrains formulation regional ecological protection land use policies. In this study, we attempted to characterize spatio-temporal from 2000 2020 Chengdu-Chongqing (CCUA), using matrix hotspot analysis tools. We then introduced optimal parametric geographic detector detect formation mechanism differentiation balance. The results show that overall index CCUA was greater than index. were short Chengdu Chongqing. had significant scale dependence. hot spots mainly western, southern, eastern mountainous regions, while cold concentrated areas Chongqing, with differences different scales. distribution affected by forest proportion, slope, normalized difference vegetation (NDVI), elevation, cultivated temperature. interaction natural, use, socio-economic factors significantly enhanced types highlights importance topography, NDVI, land, population. study can provide scientific references sustainable management construction civilization CCUA.

Ecosystem services (ESs) are closely related to human well-being (HWB). Recently, urbanization has increased worldwide, which had a significant impact on the ecosystem service supply–demand (ESSD) and HWB. However, previous studies have primarily focused spatiotemporal pattern of ESSD HWB, while ignoring their evolutionary pathways, especially in karst areas. We aimed quantify optimal trade-offs under constraints nonlinear relationship between further constructing tree-like framework explore pathways urbanization, ESSD, HWB from landscape evolution perspective. used production possibility frontier (PPF) three ESSDs, generalized additive model (GAM) fit geographic tree (Geotree) construct structure levels, comprehensive (CESD), There is trade-off deficit carbon storage (CS) water yield (WY), but synergy WY surplus FS. Further, there CSs food supply (FS). The response CS not obvious, FS obvious. Based Geotree model, CESD, present strong coupling relationships, show characteristics clustering, stratified heterogeneity, evolution.

Ecosystem services are the beneficial goods and that ecosystems provide to humans. Urbanization is an important feature of human social development. While promoting economic development, it also brings about land degradation, resource depletion, environmental pollution other problems, intensifying transformation natural into semi-natural artificial ecosystems, ultimately leading loss ecosystem service functions declining value. The study impact urbanization on value critical importance for conservation sustainable This examined spatio-temporal patterns urbanization’s impacts in Yellow River Basin from perspective heterogeneity. Findings: (1) Both (ESV) level (UL) were rise whole, but they significantly spatially negatively correlated mainly characterized by high–low spatial clustering “low ESV–high UL” “high ESV–low UL”. negative correlation was gradually weakened with development mode ecological restoration projects Basin. (2) five subsystems diverse. Landscape had a all regions; innovation changed having positive impact; demographic both impact. (3) To promote coordinated protection YRB, this paper proposes change model, implement zoning, formulate classified plans. compensates shortcomings current studies ignore different lack sufficient consideration heterogeneity characteristics ESVs, enriches theoretical understanding interrelationships between systems basin areas, provides scientific basis rational formulation urban planning policies region, which great practical significance.

The rapid urbanization process of urban agglomerations had complex and non-linear effects on various ecosystem services (ESs), particularly within mega-urban agglomerations. Previous studies have focused the impacts comprehensive ESs single However, research relationship between multi-dimensional different ES types across entire identification impact thresholds remains limited. This lack investigation has considerably hampered formulation targeted policies for development ecological management. Addressing these gaps, this study takes a holistic approach by taking BTH-UA, PRD-UA, YRD-UA as whole employs threshold regression model to measure types, along with identifying critical thresholds. results are follows: In terms temporal evolution, progressed most rapidly in contributing varying degrees decline. contrast, despite relatively low level rise. Spatially, exhibited “core-periphery” pattern both distribution. High levels were found clustered core regions, while elevated prevalent peripheries, indicating significant spatial disparities. population (PU) land (LU) carbon storage (CS) an inverted U-shaped curve 272 people/km2 1.063%, respectively. effect LU food production (FP) 0.704%. findings indicate that PU exhibit more characteristics systems. underscore significance regulating density expansion intensity improve offers valuable support policy sustainable planning large clusters.

Abstract Enhancing the understanding and management of ecosystem services (ESs) supply demand under influence global change is crucial for sustaining human well‐being promoting sustainable development. However, comprehension changes in service dynamics face complex disturbances remains limited. This study focuses on four representative ESs northern Liaodong Bay, a typical estuary wetland, to elucidate alterations these comprehend impact mechanisms arising from reclamation activities. The findings reveal following key insights: between 1993 2020, water yield disparity became increasingly pronounced, while equilibrium carbon storage shifted surplus balance. In contrast, excess supply–demand food landscape esthetics remained relatively consistent. delves deeper into non‐linear relationship activities relationships, with each exhibiting distinct patterns. As intensity rises, ratio exhibits varying trends: demonstrate an inverted U‐shaped relationship, follows pattern, progressively decline. By identifying thresholds, different strategies should be applied areas exceeding falling below constraints guidance being necessary former latter, respectively. These advance our context human‐driven provide practical implications coastal areas.

Exploring the relationship and driving forces between supply–demand of ecosystem services (ESs) urbanization can help solve environmental problems promote regional sustainable development. This study analyzed spatio-temporal distribution characteristics ESs comprehensive level (CUL) in Shaanxi Province from 2010 to 2019 assessed coupling service ratio (ESSDR) CUL using coordination degree (CCD) model. Random forests geographically weighted regression methods were utilized characterize contribution spatial drivers CCD. The results showed that: (1) except for habitat quality, ESSDR other three types as well a decreasing trend, exhibited increasing trend; (2) Although CCD was generally increasing, significant portion (78.51%) regions still remained uncoordinated, with relatively better shown around Guanzhong urban agglomeration, which has higher level; (3) primarily influenced by local financial income, secondary industry, temperature forces. In high CCD, tertiary industry decisive force. areas, there variations These findings provide coupled coordinated perspective ecological management, scientific reference practical guidance cities different development modes.

As the mainstream and trend of urban development in China, deeply exploring spatiotemporal patterns influencing mechanisms ecosystem service value Yangtze River Delta agglomeration is great significance for achieving sustainable goals agglomerations. This paper uses normalized difference vegetation index net primary productivity as dynamic adjustment factors to measure analyze its evolution characteristics. Furthermore, a panel quantile regression model constructed explore response differences at different levels various factors. The results show that: (1) From 2006 2020, decreased by 37.086 billion yuan, with high-value areas mainly concentrated southern part agglomeration. (2) structure land type ecosystems sub-services stable. (3) number grid units reduced continuously increasing, distributed eastern coastal areas. (4) degree interference types on varies, same factor also shows heterogeneity. In summary, analyzing conducive adjusting intensity human utilization protection methods ecosystems, which enhancing products
