With the rapid development of new urbanization in Yangtze River Economic Belt (YREB), it has hindered sustainable land resources and posed a great threat to regional ecological security (LES). So, is significance explore spatiotemporal evolution, convergence characteristics LES YREB. In this study, we chose panel data 11 provinces YREB from 2000 2020 measure analyze levels LES, degree differences, sources those distribution dynamics using entropy weight method, Dagum Gini coefficient three-dimensional kernel density estimation method. The study also combines variation spatial model examine context results indicate that its three main regions (upstream, midstream, downstream) are on an upward trend, showing clear pattern (high middle low east west), absolute differences decreasing. No polarization evident, between primary source overall differences. significant positive effect regions. These have number practical implications for YREB, which should take full account their environmental conditions, introduce ecology protection policies tailored local actively promote synergistic management upstream, downstream regions, provide quantitative support coordinated promotion protection.

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.

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.

The interaction between urbanization and ecosystem services (ESs) is a hot topic in the modern human-earth system science. Currently, most studies only focus on effects of ESs supply, few have accurately quantified demand explored spatial–temporal coupling interactions supply–demand balance. To address these gaps, this study used process-based modeling to estimate absolute number demand. Ecosystem ratio (ESDR) employed measure Finally, pearson correlation analysis, coordination degree model, bivariate local Moran's I method were explore interactive relationship balance Loess Plateau (LP). Results indicated that LP experienced rapid with characteristics faster economic than land population from 2000 2018. Negative correlations construction proportion ESDR enhanced over time.

Urban renewal in high-density cities presents a complex challenge when it comes to balancing social-environmental performance and economic benefits; improvements the built environment social wellbeing may be associated with substantial costs loss, particularly so where land resources are scarce highly valued. The interplay that takes place between sustainable targets tends very complicated. This study proposes decision-making support framework can quantify synergies trade-offs economic, environmental, pertaining use change public open space (OS) provision urban processes. proposed operates at both neighbourhood building levels, is comprised of three analytical components: redevelopment trend analysis module, three-dimensional simulation evaluation module. One ageing district Hong Kong, Yau Mong district, was selected as case area for this work. Six planning scenarios were which reflect various priorities principles including benefits, environmental equal distribution OS enhancing quality OS. findings suggest there trade-off relationship economic-environmental targets, synergic mediational economic-social targets. Planning strategies such rezoning, reconfigurations, plot ratio adjustment transfer development rights could triangulated strategic approaches by maximising achieve better sustainability. not only contributes theory introducing prototype comprehensive evaluate sustainability performance, but also provides important insights into reconciling divergent inherent renewal.
