摘要

The mismatch between ecosystem service (ES) supply and demand, induced by rapid urbanization, has become a critical bottleneck constraining the resilience of regional social-ecological systems. In this study, the Fuzhou Metropolitan Area (FMA) was selected as the research object. A systematic analytical framework integrating phenomenon diagnosis and mechanistic attribution was constructed. The spatiotemporal evolution of supply and demand for Food Provision (FP), Carbon Sequestration (CS), and Recreation Service (RS) was quantitatively assessed for the years 2010, 2015, and 2020. Results indicated that distinct spatiotemporal polarization was observed. Despite an upward trend in total service supply, the spatial mismatch significantly intensified. This pattern was characterized by structural deficits in central urban areas coexisting with ecological surpluses in peripheral regions. Furthermore, the formation mechanism of trade-offs was revealed. Significant trade-offs in the urban core were attributed to bidirectional divergent driving effects. These effects were primarily generated by socioeconomic factors. Specifically, these factors physically encroached upon ecological supply spaces while simultaneously amplifying social demand. Moreover, significant scale dependence was observed in the driving mechanisms. A systematic shift occurred from constraints by climatic and economic factors at the metropolitan scale to regulation by socioeconomic factors at the functional zone scale. Accordingly, a dual-scale spatial governance strategy was proposed. This strategy integrates macro-level biophysical boundary control with micro-level socioeconomic flow regulation, providing a scientific basis for balancing economic growth and climate resilience in high-density urban agglomerations.
