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.

Mapping the evolution patterns of urbanization, ecosystem service supply–demand, and human well-being: A tree-like landscape perspective

Ecological Indicators, Journal Year: 2023, Volume and Issue: 154, P. 110591 - 110591

Published: July 3, 2023

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.

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.

Non-linear effects of multi-dimensional urbanization on ecosystem services in mega-urban agglomerations and its threshold identification

Ecological Indicators, Journal Year: 2023, Volume and Issue: 154, P. 110846 - 110846

Published: Aug. 26, 2023

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.

The sustainability of coupled human and natural systems (CHANS), linked to several the United Nation's Sustainable Development Goals, affects both global sustainable development wellbeing. However, few studies have explored relationship between whole system from perspective supply demand. Based on ecosystem service concept Maslow's hierarchy needs, we constructed an services index (ESSI) a demand (HMDI) then analyzed spatial mismatch ESSI HMDI in 338 prefecture cities China. We propose supply-demand balance inspired by doughnut theory demonstrate conflicts synergies ecosystems systems. Our results show that decreased 2000 2010, but remained almost unchanged 2010 2020. low values were mainly distributed over North China Plain, Yangtze River Delta, Sichuan Basin. increased 2020, rate increase has slowed since 2010. high east coast China, Inner Mongolia, part Xinjiang province. From with mismatches showed significant agglomeration. most regions decreasing trend, higher value index, faster speed decrease. Overall, there more state conflict humans than synergistic state, although this number Urban agglomerations western should receive attention for their ecological health. This study provides new methodology assess CHANS could be applied other locations. findings support Chinese government regional governance territorial space planning.
