| 摘要: |
| ［目的］开展城市形态与城市居住用地集约利用评价的内在关联分析，可进一步揭示城市居住用地变化发展的作用机理，为科学土地利用提供理论支持与实践指导。［方法］研究以南京市江宁区为例，采用土地利用调查数据，借助集对分析法和GIS空间分析等方法，分析居住用地的集约利用程度，并结合斯皮尔曼等级相关分析与地理加权回归分析相结合的手段进行城市形态与居住用地之间的关联性分析。［结果］（1）研究区内居住用地总体集约利用水平较好，贴近度为0598 1，置信度判别等级为2，百家湖片区和秦淮河沿岸片区集约利用水平相对较高； （2）居住用地整体的紧凑度小、分形维数较大，用地较为分散，居住用地的扩展多依靠外缘增长的方式； （3）城市形态对集约利用水平具有一定影响，在影响程度和方向上空间异质性显著，改善将军山片区、牛首山片区的用地形态可提升地区的集约利用水平，而老城片区、科学园区则需着重内部改造。［结论］基于江宁区居住用地的集约利用水平，文章从城市形态与土地利用结构调整提出了相应的对策建议。 |

| Abstract: |
| An analysis of the inherent relationship between the evaluation of intensive use of urban forms and urban residential land can further reveal the function mechanism of urban residential land and provide theoretical support and practical guidance for scientific land use. Taking Jiangning District of Nanjing City as an example, taking the land use survey data as a foundation, this paper analyzed the intensive utilization of urban residential land by means of set pair analysis and GIS spatial analysis. Combined with Spearman′s rank correlation analysis and geo weighted regression analysis, the correlation between urban morphology and urban residential areas was analyzed. The results showed that: (1) The overall intensive use of the whole urban residential land in the study area was better, the closeness was 0.5981, the confidence level was 2, and the intensive utilization of the Baijiahu and Qinhuai riverside areas were relatively high; (2) The overall residential area had the advantages of small compactness, large fractal dimension and scattered land. The extension of urban residential land depended on the way of outer edge growth. (3) The urban morphology had an impact on the level of intensive utilization, The spatial heterogeneity was significant. Improving the land use patterns of General Military District and Niu Shoushan Area could improve the intensive utilization of the area, while the Old City Area and Science Park needed to rebuilt internally. Based on the intensive utilization of urban residential land in Jiangning District, the article put forward corresponding countermeasures and suggestions based on urban morphology and land use structure adjustment. |
