Spatial Morphological Studies Of Nanning San Jie Liang Xiang

San Jie Liang Xiang refers to the concentrated enclosed area of Xingning Road,Minsheng Road,Jiefang Road,Jinshi Lane and Yinshi Lane,which is the best-preserved historical block in Nanning,overlapping with diversified historical,cultural and social values.How to understand the evolution characteristics and laws of block space form,and protect and continue the historical context of block are the core of this dissertation.My research mainly uses M.R.G.Conzen s Urban Morphology theory for reference to study the evolution process and characteristic mechanism of the spatial morphology of San Jie Liang Xiang.On this basis,it discusses the application of the theory to the protection of historical blocks,and tries to put forward the method and process of establishing morphological classification guidance and control.First of all,this research traces back the background and historical evolution of San Jie Liang Xiang,and through the translation and analysis of historical maps,analyzes the block spatial pattern,street lane system and architectural types from the late Qing Dynasty to the Republic of China,and obtains the original Morphological Base.Secondly,after the founding of the Peoples Republic of China,this research divides it into three periods,analyzes the block shape elements,discusses the block shape characteristics and influencing factors in each period,and divides the block morphological regions.Furthermore,the research summarizes the general trend of the evolution process of block space morphology,and discusses the problems faced by the block in the process of renewal practice and the enlightenment of the evolution process of block space morphology.Finally,based on the objectives,principles and specific strategies of protecting and continuing the spatial pattern of blocks,this research establishes the method and process of morphology classification guidance and control,forms the guidance and control plan according to the morphological control elements,and takes some plan units for example.Based on the evolution process of physical space morphology,my research discusses the characteristics and influencing factors of the evolution of block space morphology,and puts forward targeted protection strategies according to the current situation and enlightenment of block.The research combines the form type with the form design control,and tries to establish the form control as the control guideline of the spatial form elements connecting the preceding with the following between urban design and architectural design,in order to put forward optimization strategies for integrating historical blocks with the surrounding environment,and provide reference for continuing the historical context.
