The urban–rural fringe, serving as a frontier space and protective barrier for factor circulation, is complex area marked by significant human–land conflicts. Therefore, scientifically identifying dynamically monitoring the fringe crucial its integrated development spatial governance. In this context, paper constructs an information entropy model using land use data, combined with central gravitational agglomeration method, to accurately identify evolution of Harbin’s over past 40 years. research reveals that exhibits distinct circling pattern, morphology changes characterized “low-speed spreading—jumping expansion—internal dissimilarity”, allowing improved identification three types: stable, expanding, degrading. study also tracks scale in Harbin types degrading fringe. Drawing on previous research, we visualize area’s functional positioning, showing dominant function shifting from production–ecological composite production–life–ecological coordinated function. Concurrently, study’s findings, alongside socioeconomic development, indicate fringe’s driven economic, policy, environmental factors. Based multi-dimensional outcomes, conclude can be divided into stages: slow gestation period (1980–1990), rapid (1990–2010), stable reconstruction phase (2010–2020). initial phase, urban rural minimal; during second trend expansion significant, rapidly shifted city; latter stage, elements are stabilized coordinated, areas realized developed reconstructed one. This provides scientific basis understanding dynamic City important reference future territorial planning development.

Urban agglomeration ecosystems are impacted by human activities and natural disasters, so analyzing the spatial temporal evolution of landscape ecological resilience from perspective adaptive cycling is crucial. Using Changsha–Zhuzhou–Xiangtan urban in China as a case study, this research constructs “Risk-Potential-Connectivity” framework to evaluate resilience. This applies exploratory data analysis methods examine spatiotemporal associated patterns Geodetector model measure driving factors variation. study an cycle based on analysis, integrating potential connectivity indices classify development stages regions dynamically. The results showed that overall distribution pattern risk decreased center outward, whereas increased. average index 2000 2020 was 0.31, with declining trend shifting gravity northwest southeast. toughness exhibited high low aggregation, Moran greater than 0.75.

Megacities in developing countries are still undergoing rapid urbanization, with different cities exhibiting ecosystem services (ESs) heterogeneity. Evaluating ESs among various and analyzing the influencing factors from a resilience perspective can effectively enhance ability of to deal react quickly risks uncertainty. This approach is also crucial for optimizing ecological security patterns. study focuses on Xi’an Jinan, two important megacities along Yellow River China. First, we quantified four both cities: carbon storage (CS), habitat quality (HQ), food production (FP), soil conservation (SC). Second, analyzed synergies trade-offs between these using bivariate local spatial autocorrelation Spearman’s rank correlation coefficient. Finally, conducted driver analysis Geographic Detector. Results: (1) The temporal distribution Jinan quite different, but show lower ES levels urban core area. (2) showed strong synergistic effect. Among them, CS-HQ had strongest synergy 0.93. In terms space, north dominated by low–low clustering, while south high–high clustering. FP-SC trade-off effect −0.35 2000, which gradually weakened over time was mainly distributed northern area city where cropland construction were concentrated. (3) Edge density, patch NDVI have greatest influence CS Jinan. DEM, slope, density HQ. Temperature, edge impact temperature FP cities. SC. Landscape fragmentation has great CS, HQ, SC Due insufficient research data, this focused only middle reaches River. However, results provide new solving problem regional sustainable development directions ideas follow-up field.

ABSTRACT This study empirically investigates the causal relationship between resource industry dependence and urban resilience from three perspectives: ecological, economic, social, contributing to curse theory sustainable development of resource‐dependent cities. We use entropy method establish an index system measure 269 Chinese cities 2000 2019, construct a two‐way fixed‐effects model test impact on resilience. The results show that impairs resilience, this finding remains robust estimation using instrumental variable approach. Moreover, mechanism tests undermines by inhibiting industrial structural upgrading hindering green technological innovation. further categorize into ecological economic social find has more significant negative than Our investigations suggest should develop strategies based their unique endowments reduce dependence, improve strengthening systems promoting innovation, achieve development.

Over the past two decades, urbanization in China has been advancing rapidly. The intricate effects of on vegetation growth urban core have studied and reported. However, percentage impervious surfaces core, as defined previous studies, was relatively low, included some pixels containing farmland water bodies. Consequently, their results may be affected by processes, such transformation land types. Hence, this paper extracted 100% from 2000 to 2022 areas using a 30 m resolution cover dataset (CLCD), which completely excluded effect itself experimental results, obtaining trend change real area. Employing remote sensing imagery Enhanced Vegetation Index (EVI) 2022, we analyzed 1559 cores surrounding rural China. study’s findings revealed that majority (85.3%) exhibited significant (p < 0.05) increase vegetation, indicating various greening policies effective. only about 23.7% (369) showed faster than areas. This suggests for most (1190), is not pronounced it Additionally, EVI rate obtained CLCD versus MODIS data significantly differed. latter less compared former, attributable disparity spatial methodology used define study underscores importance its distribution comprehend dynamics cores’ offer insights subsequent formulation policies. Moreover, with different resolutions will impact thus highlighting necessity employing high more comprehensive research.

The process of sustainable urban development faces complex and severe environmental problems. Therefore, enhancing ecological resilience (UER) has become an urgent critical goal. In this study, the establishment national forest cities (NFCs) in China is regarded as exogenous shock event, impact NFCs on UER its mechanisms are investigated based data from 292 spanning 2003 to 2021 using a difference-in-difference method. It found that can significantly enhance UER, conclusion holds after series robustness tests. Mechanism analysis shows effectively strengthen regulations, upgrade industrial structures, promote green innovation, thus UER. Heterogeneity indicates effect NFC more significant low-carbon non-pilot cities, with higher levels development, central western China. Spatial spillover improve neighboring cities. should be continuously implemented optimized establish long-term mechanism for forests resilience.

Abstract Digital finance, as a representative of the digital economy, provides unprecedented opportunities for enhancing adaptability and resilience ecosystems. However, there is currently no literature that integrates finance urban ecological into same research framework. In light this, we utilize panel data from 2011 to 2019 investigate impact on resilience. Our results indicate (1) can effectively enhance resilience, conclusion corroborated by both theoretical frameworks empirical evidence. Specifically, coverage breadth usage depth while digitization level has not shown significant impact. (2) Green technological innovation, improvements in energy efficiency, agglomeration producer services are identified effective channels through which promotes (3) The exhibits regional heterogeneity, with more pronounced effects observed cities advanced traditional financial systems, non‐resource‐based cities, central cities. These findings will help policymakers better understand relationship between formulate targeted policies leverage development
