Abstract

Balancing urban construction land expansion (UCE) with ecosystem health (EHI) is critical for sustainable management. This study evaluates how UCE impacts EHI across China’s cities, economic subregions, and urban agglomerations using multivariate satellite remote sensing data and spatial econometric models. Findings reveal a consistent decline in EHI, with an average annual decrease of 2.012 % between 2000 and 2023, correlating with UCE growth. Declining EHI clusters were concentrated in major urban agglomerations, notably BTH, GBA, and YRD. The analysis highlights a strong negative spatial dependency, with mature urban agglomerations experiencing significant spillover effects, while emerging regions faced more direct impacts. The research underscores the need for cross-regional ecological governance and tailored strategies to enhance ecological resilience in urban development.

中国城市建设用地快速扩张对生态系统健康空间不平等的影响——基于国家、经济区域和城市群视角的证据

平衡城市建设用地扩张与生态系统健康是城市建设用地可持续管理的关键。本研究利用多变量卫星遥感数据和空间计量经济模型，评估了城市经济效益对中国城市、经济次区域和城市群的影响。研究结果显示，EHI持续下降，在2000年至2023年期间平均每年下降2.012%，与UCE增长相关。EHI下降的集群集中在主要城市群，特别是北京、大湾区和长三角。分析结果表明，城市群经济发展存在较强的负空间依赖关系，成熟城市群的溢出效应显著，新兴城市群的溢出效应更为直接。该研究强调了跨区域生态治理和定制战略的必要性，以增强城市发展中的生态弹性。

期刊介绍： The ultimate aim of Ecological Indicators is to integrate the monitoring and assessment of ecological and environmental indicators with management practices. The journal provides a forum for the discussion of the applied scientific development and review of traditional indicator approaches as well as for theoretical, modelling and quantitative applications such as index development. Research into the following areas will be published. • All aspects of ecological and environmental indicators and indices. • New indicators, and new approaches and methods for indicator development, testing and use. • Development and modelling of indices, e.g. application of indicator suites across multiple scales and resources. • Analysis and research of resource, system- and scale-specific indicators. • Methods for integration of social and other valuation metrics for the production of scientifically rigorous and politically-relevant assessments using indicator-based monitoring and assessment programs. • How research indicators can be transformed into direct application for management purposes. • Broader assessment objectives and methods, e.g. biodiversity, biological integrity, and sustainability, through the use of indicators. • Resource-specific indicators such as landscape, agroecosystems, forests, wetlands, etc.
