Research On Street Network Generation Method Based On Spatial Texture Characteristics In Urban Historical Area

With the process of urbanization,the functional replacement and renewal of urban historical area becomes an important part of urban design and the existence of spatial texture has become the focus of work.However,the single emphasis on the importance of society,economy and culture ignores the important role of spatial texture,resulting in the phenomenon of mixed urban spatial texture and broken thread of morphological inheritance.Scientific methodology is urgently needed to guide the morphological design of cities,especially in historical area.Compared with traditional urban analysis methods,the application of quantitative research and digital generation technology provides a strong technical support for the renewal design of urban historical area.Taking urban street network as the main research object,this thesis uses quantitative analysis and digital generation technology to explore the street network generation method in urban historical area.It provides a design reference for urban renewal design,and then helps considering the new direction of urban renewal.The main research includes: establishing the evaluation and expression system of street network morphology,developing case-based algorithm tool of street network generation,clarifying the applicable scope of the method and proposing further optimization directions through the experiment and corresponding data verification of street network generation in Nanjing Chengnan District.
