| 英文摘要 | The ecological supply-demand mismatch resulting from rapid urbanization stands as a core challenge affecting regional sustainability. This study constructed ecological supply-demand networks from the perspective of the circulation of ecological processes flow within regions, and proposed a novel supply-demand relationships evaluation index system. The case study results of six typical cities in the 'Upstream-Midstream-Downstream' of the Yellow River Basin demonstrate that our proposed evaluation index system can more accurately reveal the dynamic interaction of ecological resources within the urban area and the degree of supply-demand mismatch. Additionally, we found that the supply-demand relationship in upstream cities is better than that in midstream and downstream cities, with downstream cities exhibiting the worst performance. Furthermore, over the past 20 years, the supply-demand relationships of all six cities have consistently deteriorated, with the maximum decline reaching 39.8 %. Social development factors have driven imbalance changes in ecological resource allocation and spatial connectivity between the supply and demand sides, serving as a key factor in driving the deterioration of urban ecological supply-demand relationships. Lastly, this study proposes a partitioned protection strategy adaptable to both the basin and individual cities. This study holds significant importance for optimizing the allocation of ecological supply-demand resources and protecting ecosystems in different watershed segments. |
