Study On The Optimization Design Of The Space Form Of The Section North Of Wusong Road In Changchun South Square

As one of the key conservation objects in Changchun,the overall spatial pattern of the South Square Historical and Cultural District and its internal historical buildings carry the culture and background of Changchun’s development process,in which the historical buildings in the district north of Wusong Road and their surrounding environment together form a complete spatial form and convey the complete historical information of the district.At present,some of the historical buildings in the neighborhood have been demolished and cannot be restored,and the traditional "point conservation model" can no longer adapt to the rapid development stage of the city,especially the lack of systematic research methods for the historical and cultural neighborhoods at the medium and micro levels,which leads to the integrity and continuity of the neighborhood being hindered to a certain extent.Based on the research method of urban spatial morphology from two-dimensional plane to three-dimensional space,this paper combines the current morphology-related technical means,refers to the typical cases of morphological research on historical and cultural districts at home and abroad,and analyzes the road,street outline and group,and architectural morphological characteristics of the lot north of Wusong Road in South Square historical and cultural district from macroscopic to microscopic,from material elements to place cognition,so as to provide different ideas for the subsequent optimization of the historical and cultural district.It provides different ideas and research methods for the subsequent optimization of the historical and cultural district as a whole.This paper is divided into four parts: the first part(Chapter 1)is the introduction which presents the technical line of the research based on the research background and the current situation of domestic and international research,etc.The second part(Chapter 2)is the morphological composition and influencing factors of the historical and cultural district,which elaborates the evolution of the spatial form and morphological characteristics of the district from the historical background,social culture and physical environment of the South Square district as a whole.The third part(Chapter 3)is the focus of this study: the study of the spatial morphology of the neighborhood north of Wusong Road in South Square,analyzing the current situation at three levels: road morphology,plot morphology and architectural morphology,and using qualitative and quantitative methods to classify and elaborate the spatial morphological characteristics of the selected neighborhood.The fourth part(Chapter4)is a study on the optimized design of the spatial morphology of Wusong Road North neighborhood.Based on the analysis of the current situation of the spatial morphology of the neighborhood,a targeted optimized design framework is established for the morphological characteristics of the selected parcels,and at the same time,using the research method of urban design,optimized design strategies are proposed for the neighborhood roads,functional zoning and integration of the parcels,and the relationship between the architectural morphology and the surrounding environment.The fifth part is the conclusion,which summarizes the morphological characteristics and optimization strategies of each level of elements in the South Square historical and cultural district.
