近代中国留下一笔丰厚的城市空间遗产，但现行旧城改造模式忽略和破坏了其城市活力与多样性。近代城市空间体现了具有中国特色的现代空间类型和系统演进模式，对其开展研究可为近代历史街区保护和再生的规划设计提供基础。本课题将基于复杂系统理论，运用城市形态学分析方法，深入解析多进程、多尺度的空间系统等级化发展。.本课题将1）建构近代城市空间形态演进的理论模型，提出分阶段、分层面的空间形态演进的分析框架；2）依托申请人已建立的上海近代历史空间GIS数据库，对近代上海法租界案例开展实证研究，对建筑单体进行全面调查，完成从个体层面的基础类型界定，进而探讨在地块－街坊－城区三个尺度上的不同空间类型，运用空间聚类分析方法，剖析它们在不同进程阶段中的相互作用关系，提出空间形态演进的模式；3）与近代历史街区保护和再生的规划设计进行对接机制研究，明确值得保留的空间形态类型，确定再生地块选取标准，探究空间重组的设计策略。

Pre-modern China left behind a rich legacy of urban space, but the existing transformation models of old city ignore and even destroy its urban dynamic and diversity. Pre-modern urban space systematically reflects a variety of modern urban spatial types and their integrated evolution model with specific Chinese characteristics, and therefore the relevant studies provide references to current planning and design of historic neighborhoods redevelopment. Based on complex system theory and the methodology of urban morphology, this research will analyze multi-phase and multi-scale space evolution of pre-modern urban spatial form. .The research will 1) build a theoretical model for pre-modern urban spatial form evolution and propose an analytical framework of spatial form evolution at different phases and scales, 2) conduct an empirical study of pre-modern Shanghai French Concession based on the GIS database of pre-modern Shanghai historic neighborhoods established by the applicant. A typology of spatial form at three scales, including parcel, neighborhood and urban area will be identified, as well as their multiple features. The interaction among space of different scale at different phase will be explored through cluster analysis, and then the model of spatial form evolution will be built; 3) investigate a joint mechanism with planning and design of historic neighborhoods’ redevelopment. The spatial forms worth of reserving will be identified and the standard of choosing regeneration parcels will be established. It is followed by an exploration of multiple possibilities to restructure historic urban space.
