Assessing the Supply–Demand Matching and Spatial Flow of Urban Cultural Ecosystem Services: Based on Geospatial Data and User Interaction Data

Land, Journal Year: 2025, Volume and Issue: 14(4), P. 773 - 773

Published: April 3, 2025

Cultural ecosystem services (CESs) reflect the interaction between ecosystems and human well-being. Owing to constraints in data availability existing methodological limitations, deriving information from non-material attributes was inadequate. We took Yulin City, located northern Shaanxi Loess Plateau, as a case study. Based on open-source geospatial user social media, coupled multi-source model applied elucidate spatial distribution of CESs’ supply–demand flow. The Maxent LDA were utilized quantify CES supply–demand, whereas breakpoint gravity explain direction intensity results indicated following: (1) aesthetic most perceivable Yulin, with 27% high supply areas four demand topics. And perception educational least pronounced, only 2% two (2) exhibited notable mismatching matching area constituting approximately 10%. In center city, CESs displayed pattern deficit, while farther city presented surplus. (3) flow followed movement peripheral counties central less developed more counties. proposed following targeted recommendations: introducing low-perception promote enhancement (ESs); alleviating mismatches by enhancing transportation accessibility protecting ecological environment. Simultaneously, attention should be directed towards developmental disparities counties, providing differentiated guidance for Our study provided theoretical foundation understanding offered scientific insights development urban CES.

Balancing Act on the Third Pole: Three Decades of Ecological-Economic Synergy and Emerging Disparities Along the Qinghai–Tibet Railway, China

Sustainability, Journal Year: 2025, Volume and Issue: 17(8), P. 3345 - 3345

Published: April 9, 2025

The Qinghai–Tibet Plateau (QTP), a critical ecological buffer for Asia, faces intensifying pressures from climate change and infrastructure expansion. Railway (QTR), as the world’s highest-altitude railway, traverses this fragile yet economically vital region, where balancing ecosystem integrity development remains global sustainability challenge. While previous studies have documented localized environmental impacts of QTR, systematic assessments long-term ecological-economic interactions—particularly synergies trade-offs between service value (ESV) economic growth—are lacking. This gap hinders targeted policy design to reconcile conservation in extreme environments. present research integrates an enhanced valuation framework with spatial econometric modeling quantify changes coordination Region (QTRR) during 1990–2020. analysis reveals cumulative ESV increase USD 54.4 billion over past 30 years, driven primarily by grassland restoration regulated land use transitions. Notably, county-level improved significantly, harmonization indices rising 32–68% across all jurisdictions. However, latent risks emerged: five counties exhibited severe ecosystem-health-to-economy mismatches 2020. These findings demonstrate that corridors ecosystems can achieve partial through interventions, persistent local disparities demand spatially differentiated management. By linking dynamics governance pathways—including livestock–forage balance mechanisms green urban zoning—the study provides transferable assessing Broader implications highlight necessity embedding adaptive thresholds into planning, offering experiences Belt Road Initiative other high-altitude frontiers.

Spatio-Temporal Variations of Soil Conservation Service Supply–Demand Balance in the Qinling Mountains, China

Land, Journal Year: 2024, Volume and Issue: 13(10), P. 1667 - 1667

Published: Oct. 13, 2024

The ecological conservation of nature reserves has garnered considerable attention and is subject to stringent management in China. However, the majority these areas have a history underdeveloped economies require urgent improvements well-being local communities. Effectively coupling harmonizing dynamic relationship between ecosystem services socio-economic development emerged as crucial concern for reserves. Therefore, further exploration needed achieve spatio-temporal balance alignment supply demand ESs Utilizing multiple datasets, RULSE, bivariate autocorrelation methods, this study investigated evolution supply–demand ratio (ESDR) spatial matches soil (SCSs) Qinling Mountains (QMs) from 2000 2020. results indicated following: (1) Over years, SCSs exhibited consistently high level, with an upward trend observed 63.10% QMs, while generally low, decreasing 82.68% QMs. (2) remained favorable, positive ESDR reaching 82.19% From 2010, there was significant decline ESDR; however, substantial rebound across region 2010 (3) counties districts values ESDR. When examining cities, Weinan, Xi’an, Ankang demonstrated relatively consistent patterns higher over time. In 2000, on northern slope lower than that southern slope; situation subsequently underwent reversal. (4) distribution SCS predominantly characterized by matching regions exhibiting either High Supply–High Demand or Low Supply–Low years. This suggests dynamics been favorable recent matches. These findings can provide valuable insights similar aiming implement environmental protection sustainable development. future research endeavors, should strive expand upon exploring associated other diverse reserves, considering their unique geographical characteristics, order promote more rational strategies.
