With global urbanization on the rise, China has entered mid-to-late stage, and Cheng-Yu region, as a key economic zone new model in China, faced water environmental issues due to rapid urbanization, while systematic research synergy between its environment governance remains scarce. This study explores spatiotemporal evolution of optimization strategies for coupling coordinated development region. A comprehensive evaluation index system was established measure Urbanization Development System (UDS) Water Environment Governance (WEGS), coordination utilized analyze relationships two systems from 2013 2021. The showed steady upward trend 2021, evolving state severe imbalance high-level coordination. Initially, UDS relatively low, WEGS higher but grew at slower rate. After 2019, caused exceed level WEGS, indicating growing pressures. Moreover, there are persistent disparities among cities. Industrial cities like Chengdu, with high low urgently need enhance resource management. In contrast, such Dazhou, which have UDS, should make full use their resources drive sustainable urban development. For policymakers, this provides practical guidelines, suggesting targeted investment treatment facilities industrial Chengdu promoting water-based Dazhou. It emphasizes importance balancing sustainability. findings not only deepen understanding dynamic interactions also lay solid foundation optimizing future policies region other similar areas.

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.

The Impact of Rapid Urbanization on the Efficiency of Industrial Green Water Use in Urban Agglomerations around Poyang Lake

Sustainability, Journal Year: 2024, Volume and Issue: 16(19), P. 8698 - 8698

Published: Oct. 9, 2024

The construction of urban agglomerations around Poyang Lake is an important starting point the strategy for improvement central China, but spatial agglomeration industry and population brings great pressure to ecological environment. It practical value explore impact rapid urbanization on water use efficiency functional areas. Considering undesired output industrial production, this paper adopts SE-SBM model measure green efficiency, comprehensively considers different aspects Lake, empirically tests its inhibiting or boosting effect explores spillover with help a metrology model. results show that (1) shows overall upward trend, cities significantly higher than non-central continues state diffusion; (2) social urbanization, environmental balanced can improve while industrialization inhibits in efficiency; (3) considering factor, there are significant positive local effects between urbanization; (4) original pass significance test by replacing output-oriented input-oriented non-oriented study area extended Jiangxi Province, basically consistent. We should adhere new type improves well-being friendly environment, rationally plan pattern agglomerations, threshold undertaking transfer, promote flow sharing production factors.
