基于耦合模型的城市化质量与城市土地集约利用协调发展研究——以湖南省14个设区市为例

Research on the Coordinated Development of Urbanization Quality and Urban Land Intensive Utilization Based on the Coupling Model—Taking 14 Districted Cities in Hunan Province as an Example

通过构建城市化质量与城市土地集约利用的综合评估框架,利用ArcGIS10.6平台深入剖析两者的耦合与协同发展状况,并揭示其在湖南省范围内的时空演变特征。分析结果显示,湖南省各城市在城市化进程与土地集约利用上的协同性逐年增强,城市发展展现出积极向上的动态趋势。同时,这一协同发展的空间分布呈现出显著的地域差异,形成了具有区域特色的集聚模式。具体而言,东部城市展现出较高的协同水平,长沙与岳阳长期维持着良好的协调状态;相比之下,西部城市尤其是湘西自治州首府,其协同水平较低,长期处于调整阶段;而南部城市则多处于转型适应期。By constructing an integrated assessment framework of urbanization quality and urban land intensive use, the ArcGIS10.6 platform is used to deeply analyze the coupling and synergistic development of the two, and reveal their spatial and temporal evolution characteristics within Hunan Province. The analysis results show that the synergy between urbanization and intensive land use in Hunan Province has increased year by year, and urban development shows a positive dynamic trend. At the same time, the spatial distribution of this synergistic development presents significant geographical differences, forming a clustering pattern with regional characteristics. Specifically, cities in the east show a high level of synergy, with Changsha and Yueyang maintaining good coordination for a long time;in contrast, cities in the west, especially the capital of Xiangxi Autonomous Prefecture, have a low level of synergy and are in a long-term adjustment stage, while cities in the south are mostly in a period of transition and adaptation.
