| 摘要: |
| 基于对上海市虹镇老街和世博园北岸两个典型绅士化改造片区城市形态的空间强度特征值和空间结构特征值量化分析,建立模糊数学综合评估模型,综合评估城市形态模糊系数（IUF）,揭示城市绅士化改造对城市形态的影响以及绅士化街区城市形态特征.研究结果表明,与保留街区或部分绅士化街区相比,大部分绅士化程度高的街区具有高容积率、封闭性和空间隔离等空间形态特征,城市形态模糊系数较高的绅士化街区,其城市形态特征主要表现在具有良好的可达性和多功能的土地开发利用；模糊数学综合评价法能够客观地反映研究区域的城市形态特征,为城市形态的综合定量分析提供了一种有效途径.在存量规划语境下,本研究结果为制定可持续的城市改造、设计和规划方案提供参考. |

| Abstract: |
| In order to reveal the influence of gentrification of Chinese cities on urban form and the urban form characteristics of gentrification neighbourhoods, the urban fuzzy index (IUF) was applied to coordinate the characteristic parameters of space intensity value and space structure value of urban form based on two typical gentrification neighbourhoods in Shanghai. Results showed that the quality of urban form of most gentrification blocks were scored more poorly than conserved blocks or partly gentrified blocks, which was mainly due to high floor area ratio, closure, and space isolation. The gentrification blocks with high IUF were mainly characterized by good accessibility and mixed-use development. The fuzzy comprehensive assessment method can objectively reflect the urban form characteristics of the research area and supply an effective approach for the quantitative analysis of urban form. The research results will provide guidance for the formulation of urban reconstruction, design, and planning schemes. |
