| 中文摘要 |
| 以中原城市群29个地级市为研究对象，运用熵权-TOPSIS法、修正引力模型、社会网络分析及空间面板回归模型，系统解析2005~2023年中原城市群城市更新与生态韧性的时空演变特征、空间关联网络结构及溢出效应机制. 结果表明：①中原城市群城市更新综合指数呈阶梯式增长态势，空间上形成以郑州为核心、洛阳和南阳为次级中心的“核心-次级-外围”结构，邢台和商丘等城市后发优势显著，而晋南和豫西边缘城市更新相对滞后. ②生态韧性均值从0.41提升至0.45，但空间分异显著. 郑州以0.91保持绝对领先，但邯郸、平顶山等资源型城市因长期资源开发呈衰退态势，商丘虽通过生态治理实现韧性提升但辐射效应有限. ③城市更新与生态韧性空间关联网络呈现从单中心极化向多核心网络化转型特征，网络密度处于0.2~0.3的较低水平，整体呈“东密西疏”格局. 郑州始终为核心节点，度数中心度与中介中心度显著高于其他城市，东部平原依托交通优势形成紧密关联，西部受地形限制呈“孤岛链”结构. ④城市更新对本地生态韧性存在显著的正向影响，但对邻近区域则呈现负向溢出效应. 产业结构优化对生态韧性具有正向空间溢出，而城镇化率提升则可能通过生态空间挤压对周边产生负向影响. 研究结果可为优化区域生态-城市协同治理、推动城市群可持续发展提供理论依据与决策参考. |
| 英文摘要 |
| Focusing on 29 prefecture-level cities in the Central Plains Urban Agglomeration （CPUA）， this study employs the entropy-weighted TOPSIS method， a modified gravity model， social network analysis （SNA）， and spatial panel regression models to systematically examine the spatiotemporal evolution characteristics， spatial correlation network structure， and spillover effect mechanisms between urban renewal and ecological resilience from 2005 to 2023. The results reveal that： ① The comprehensive urban renewal index exhibited a “stepwise growth” trend， spatially forming a “core-secondary-periphery” structure with Zhengzhou as the core and Luoyang and Nanyang as secondary centers. Cities such as Xingtai and Shangqiu demonstrated notable late-mover advantages， while marginal cities in southern Shanxi and western Henan lagged behind. ② The mean ecological resilience increased from 0.41 to 0.45， yet spatial heterogeneity remained significant. Zhengzhou maintained an absolute lead （0.91）， whereas resource-dependent cities like Handan and Pingdingshan showed declining trends due to prolonged resource exploitation. Although Shangqiu improved its resilience through ecological restoration， its spillover effects remained limited. ③ The spatial correlation network between urban renewal and ecological resilience transitioned from a single-core polarized pattern to a multi-core networked structure， with network density at a relatively low level （0.2-0.3） and an overall “dense east， sparse west” distribution. Zhengzhou consistently served as the core node， exhibiting significantly higher degree centrality and betweenness centrality than those of other cities. The eastern plains formed tight linkages leveraging transportation advantages， while the western region displayed an “isolated island chain” structure due to topographic constraints. ④ Urban renewal exerted a significant positive local effect on ecological resilience but generated negative spillovers on neighboring areas. Additionally， industrial structure optimization positively influenced resilience with spatial spillovers， whereas urbanization may impose negative impacts on surrounding regions through ecological space compression. These findings provide theoretical and policy insights for optimizing regional eco-urban collaborative governance and promoting sustainable urban agglomeration development. |
