| As China enters a new stage of modern and high-quality development,urban construction has begun to change from quantitative expansion to qualitative enhancement.The preservation and utilisation of historical and cultural districts,as a unique identity of urban culture,plays a crucial role in establishing cultural confidence,inheriting urban culture and promoting high-quality development.The thesis identifies and analyses the cultural genes within the Shengjin Pagoda Historical and Cultural District of Nanchang from the perspective of history and culture,and carries out renovation and design practices for the purpose of cultural inheritance in order to deepen the depth of research on the conservation and utilisation of historical and cultural districts.Taking cultural genes as the research perspective,this study combines literature search,field research,multidisciplinary synthesis and graphical analysis to conceptualise the identification method of cultural genes and explore new ideas for the conservation and utilisation of historical and cultural districts.Based on the interpretation that cultural genes are analogous to biological genes,the cultural gene carriers of the Shengjin Pagoda Historical and Cultural District are extracted.This is subdivided into explicit gene carriers,which include point-like architectural units,linear street patterns,block-like plaza nodes and facet-like spatial texture,and recessive gene carriers,which cover historical heritage,economic industries and social life.The core and most representative cultural factors in the neighbourhoods are accurately captured and a cultural gene map is constructed.This will lead to the identification and analysis of cultural genes and the formulation of strategies for the conservation and utilisation of historical and cultural districts,and ultimately to the cultural heritage of historical districts.According to the above research ideas,the study is divided into six parts as follows:In the first chapter,after combing through the research analysis related to the topic and grasping the research developments at home and abroad,the overall research idea of the study is determined.With the ultimate aim in mind,the research methodology and framework are defined.In the second chapter,an overall analysis of the origin and development,characteristics and types,roles and manifestations of the cultural gene theory,before determining the basic methods of gene extraction and conservation principles,and summarising the carrier manifestations,classification methods and hierarchical system of cultural genes in historic districts.Combined with the support of theories from related disciplines,it provides the relevant theoretical basis for further research.In Chapter three,after understanding the urban cultural background of Nanchang and the basic overview of the Shengjin Pagoda Historical and Cultural District,a multidisciplinary integrated approach is applied to extract the cultural gene fragments within the Shengjin Pagoda Historical and Cultural District,and analyse the explicit and recessive carriers in a structured and hierarchical manner respectively to construct a cultural gene map of the Shengjin Pagoda Historical and Cultural District.Chapter four summarises the current problems and needs of the people in the Shengjin Pagoda Historic Quarter in Nanchang,and draws analogies with other types of historic and cultural quarter development models in China,so as to draw ideas for the conservation and utilisation of the historic and cultural quarter.In Chapter five,the conservation methods and renovation and utilization strategies of the historic district are applied to the design practice of the Shengjin Pagoda Historical and Cultural District,in the hope of making more useful exploration for the conservation and utilization of the historic district.Chapter six summarises the whole text,presents the conclusions and innovations of this research,and points out the shortcomings. |
