| Currently,traditional residential areas in our country are faced with the dual challenge of conservation and regeneration in the background of rapid development.Focusing on the problems existing in the conservation and regeneration process,the Xiaoxihu District is taken as an example for empirical analysis.This paper focuses on problem-oriented research and follows the concept of “Combing through the literature—Field research—Theoretical research—Design practice”.It reveals the dual connotations of the concrete and abstract aspects of property plot and clarifies the role of property plot in shaping the feature and evolution of traditional Chinese cities,and the use of property plot in conservation and regeneration practices of traditional residential area.The text is divided into three chapters.In the second chapter,historical research and analysis are conducted of the dual attributes of historic district and urban shantytowns,while pointing out the challenges and potential of conservation and regeneration.The third chapter describes the logical framework of form formation and interpretation.It analyzes the spatial evolution of the material structure of Xiaoxihu District from the diachronic and synchronic dimensions,including the street and lane system,the sequence of property right blocks,and the urban tissue.Morphological research results guide the design practice.Chapter 4 discusses the three key areas of conservation and regeneration of the Xiaoxihu District: a unified working basis,dynamic planning,and detailed design subdivisions,and implements “small-scale,gradual” protection based on property right plots.The consensus of regeneration and the principle of infrastructure advancement combine top-down and bottom-up dynamic planning to support policy design and material space planning.To sum up,the practice of Xiaoxihu is to become a beneficial exploration of the “small-scale,gradual” regeneration model,which provides new technical support for the research on the regeneration methods of other traditional residential areas in China. |
