In this paper, entropy, coupling coordination degree, spatial auto-analysis, LISA time path, and other methods have been used to analyze the coupling coordination degree of urban resilience and urbanization quality of 14 cities in Liaoning Province from 2009 to 2019. The results show that: 1. The number of highly resilient cities accounts for 14.3% of the total number of cities in Liaoning Province, and the overall resilience degree is low; the spatial distribution shrinks along the Shenyang-Dalian Economic Belt toward both sides, with obvious "core-margin" characteristics. 2. The average score of urbanization quality increased from 0.0574 to 0.0966, showing a fluctuating upward trend; the regional difference was significant, and the "dual-core" characteristic was prominent. 3. During the study period, the 14 cities of Liaoning Province were in a state of imbalance, and there was a positive correlation between the coupling degree and the coordination degree. Moran's I decreased from 0.237 to 0.220 and the spatial agglomeration characteristics also weakened. Further analysis of the spatial and temporal linkage characteristics of the coupling relationship shows that the relative length of LISA time path presents characteristics of protrusion in the central region and shrinkage on the East and West sides, and the curvature presents characteristics that are smaller in the North and larger in the South.
本文运用熵值法、耦合协调度模型、空间自相关分析、LISA 时空路径等方法,对 2009—2019 年辽宁省 14 个城市的城市韧性与城市化质量的耦合协调度进行了分析。结果表明:①高韧性城市数量占辽宁省城市总数的 14.3%,整体韧性水平较低;空间分布沿沈大经济带向两侧收缩,具有明显的“核心-边缘”特征。②城市化质量平均得分由 0.0574 上升至 0.0966,呈波动上升趋势;区域差异显著,“双核”特征突出。③辽宁省 14 个城市处于非均衡发展状态,耦合度与协调度呈正相关,Moran's I 指数由 0.237 下降至 0.220,空间集聚特征减弱。进一步对耦合关系的时空关联特征进行分析发现,LISA 时间路径的相对长度呈现出中部地区凸起、东西两侧收缩的特征,曲率呈现出北部较小、南部较大的特征。
